16-Axis MACRO CPU Software Reference Manual
16-AXIS MACRO STATION MI-VARIABLE REFERENCE
The 16-Axis MACRO Station is set up through its own set of initialization I-variables, which are distinct
from the I-variables on PMAC. Usually, they are referenced as MI-variables (e.g. MI900) to distinguish
them from the PMAC’s own I-variables, although they can be referenced just as I-variables.
These MI-variables can be accessed from the Turbo PMAC2 Ultralite through the on-line
MS{node#},MI{variable#} read and MS{node#},MI{variable#}={constant} write
commands, or the MSR{node#},MI{variable#},{PMAC variable} read-copy and
MSW{node#},MI{variable#},{PMAC variable} write-copy commands (either on-line or
background PLC), where {node#} specifies the MACRO node number (0 to 15), {variable#}
specifies the number of the Station MI-variable (0 - 1999), {constant} represents the numerical value to
be written to the Station MI-variable, or {PMAC variable} specifies the value to be copied to or from
the Station MI-variable.
For most Station MI-variables, the {node#} specifier can take the number of any active node on the
station (usually the lowest-numbered active node). These variables have MS{anynode} in the header of
their descriptions below.
However, there are several node-specific MI-variables. These variables are in the range MI910 to MI939.
For these variables, the node specifier must contain the specific node number for the MACRO node they
affect. These variables have MS{node} in the header of their descriptions below.
Global MI-Variables
MS{anynode},MI0 Station Firmware Version (Read Only)
Range: 1.200 - 9.999
Units: Revision numbers
Example:
MS0,MI0
1.200
MS{anynode},MI1 Station Firmware Date (Read Only)
Range: 01/01/00 – 12/31/99
Units: MM/DD/YY
This variable, when queried, reports the date of implementation of the firmware on the 16-Axis MACRO
Station. The date is reported in the North American style of month/day/year with two decimal digits for
each.
The PMAC command MSDATE, which polls this value, turns the year into a 4-digit value before
reporting the value to the host computer.
MS{anynode},MI2 Station ID and User Configuration Word
Range: $000000 - $FFFFFF
Units: none
Default: 0
This variable permits the user to write a station identification number to the 16-Axis MACRO Station.
Typically, when the software setup of a Station is complete, a unique value is written to this MI-variable
in the station, and saved with the other MI-variables. On power-up/reset, the controller can query MI2 as
a quick test to see if the Station has been set up properly for the application. If it does not report the
expected value, the controller can download and save the setup values.
16-Axis MACRO Station MI-Variable Reference 1
Page 10
16-Axis MACRO CPU Software Reference Manual
MS{anynode},MI3 Station Rotary Switch Setting
Range: $00 - $FF
Units: none
This variable, when queried, reports the setting of the two rotary hex switches on the 16-Axis MACRO
Station. The first hex digit reports the setting of SW1; the second reports the setting of SW2.
Note:
It is possible to write a value to this variable, but this should not be done.
MS{anynode},MI4 Station Status Word (Read Only)
Range: $000000 - $FFFFFF
Units: Bits
This variable, when queried, reports the value of the current status word bits for the 16-Axis MACRO
Station. The value reported should be broken into bits. Each bit reports the presence or absence of a
particular fault on the Station. If the bit is 0, the fault has not occurred since Station faults were last
cleared. If the bit is 1, the fault has occurred since Station faults were last cleared.

Any of the fault bits that are set can be cleared with the MSCLRF{anynode} (clear fault) command, or
the MS$$${anynode} (Station reset) command.
2 16-Axis MACRO Station MI-Variable Reference
Page 11
16-Axis MACRO CPU Software Reference Manual
MS{anynode},MI5 Ring Error Counter
Range: $000000 - $FFFFFF
Units: Error Count
This variable, when queried, reports the number of ring communications errors detected by the 16-Axis
MACRO Station since the most recent power-up or reset.
Note:
It is possible to write a value to this variable, but this should not be done if you are
using MI6
The ring error counter value can be cleared to zero using the or MS$$${anynode} commands.
MS{anynode},MI6 Maximum Permitted Ring Errors in One Second
Range: $0000000 - $FFFFFFF
Units: Errors per second
Default:
This variable sets the maximum number of ring errors that can be detected by the 16-Axis MACRO
Station in a one second period without causing it to shut down for ring failure.
MS{anynode},MI7 (Reserved for future use)
Range: 0
Units: none
Default: 0
MS{anynode},MI8 MACRO Ring Check Period
Range: 0 - 255
Units: Station phase cycles
Default: 8
MI8 determines the period, in phase cycles, for the 16-Axis MACRO Station to evaluate whether there
has been a MACRO ring failure or not. Every phase cycle, the Station checks the ring communications
status. In MI8 phase cycles (or MACRO ring cycles), the Station must receive at least MI10 “sync
packets” and detect fewer than MI9 ring communications errors, to conclude that the ring is operating
correctly. Otherwise, it will conclude that the ring is not operating properly, set its servo command output
values to zero, set its amplifier enable outputs to the “disable” state, and force all of its digital outputs to
their “shutdown” state as defined by I72-I89, and report a ring fault.
If MI8 is set to 0 at power-on/reset, the 16-Axis MACRO Station will automatically set it to 8.
MS{anynode},MI9 MACRO Ring Error Shutdown Count
Range: 0 - 255
Units: none
Default: 4
MI9 determines the number of MACRO communications errors detected that will cause a shutdown fault
of the 16-Axis MACRO Station. If the Station detects MI9 or greater MACRO communications errors in
MI8 phase (MACRO ring) cycles, it will shut down on a MACRO communications fault, turning off all
outputs.
The Station can detect one ring communications error per phase cycle. Setting MI9 greater than MI8
means that the Station will never shut down for ring communications error.
16-Axis MACRO Station MI-Variable Reference 3
Page 12
16-Axis MACRO CPU Software Reference Manual
The Station can detect four types of communications errors: byte violation errors, packet checksum errors,
packet overrun errors, and packet under run errors. If MI9 errors have occurred in the MI8 check period,
and at least half of these errors are byte “violation” errors, the Station will conclude that there is a ring
break immediately upstream of it (if there are no ring input communications to the Station, there will be
continual byte violation errors). In this case, not only will it set its servo command output values to zero,
set its amplifier enable outputs to the “disable” state, and force all of its digital outputs to their
“shutdown” state as defined by I72-I89, but it will also turn itself into a master so it can report to other
devices downstream on the ring.
If MI9 is set to 0 at power-on/reset, the 16-Axis MACRO Station will automatically set it to 4.
MS{anynode},MI10 MACRO Sync Packet Shutdown Count
Range: 0 – 65,535
Units: none
Default: 4
MI10 determines the number of MACRO ring “sync packets” that must be received during a check period
for the Station to consider the ring to be working properly. If the Station detects fewer than MI10 sync
packets in MI8 phase (MACRO ring) cycles, it will shut down on a MACRO communications fault,
setting its servo command output values to zero, setting its amplifier enable outputs to the “disable” state,
and forcing all of its digital outputs to their shutdown state as defined by I72-I89.
The node number (0-15) of the sync packet is determined by bits 16-19 of Station variable MI996. On the
16-Axis MACRO Station, this is always node 15 ($F), because this node is always active for MACRO
Type 1 auxiliary communications.
The Station checks each phase cycle to see if a sync packet has been received or not. Setting MI10 to 0
means the Station will never shut down for lack of sync packets. Setting MI10 greater than MI8 means
that the Station will always shut down for lack of sync packets.
If MI10 is set to 0 at power-on/reset, the 16-Axis MACRO Station will automatically set it to 4.
MS{anynode},MI11 Station Order Number
Range: 0 – 254
Units: none
Default: 0
MI11 contains the station-order number of the 16-Axis MACRO Station on the ring. This permits it to
respond to auxiliary MACROSTASCII<n=Station Order Number> commands from a Turbo PMAC ring
controller, regardless of the 16-Axis MACRO Station’s rotary-switch settings.
The station ordering scheme permits the ring controller to isolate each master or slave station on the ring
in sequence and communicate with it, without knowing in advance how the ring is configured or whether
there are any conflicts in the regular addressing scheme. This is very useful for the initial setup and
debugging of the ring configuration.
Normally, station order numbers of devices on the ring are assigned in numerical order, with the station
downstream of the ring controller getting station-order number 1. This does not have to be the case,
however.
Unordered stations have the station-order number 0. When the ring controller executes a
MACROSTASCII255 command, the first unordered station in the ring will respond.
MI11 can also be set with the ASCII command STN={constant}. The value of MI11 can also be

MS{anynode},MI12 Card Identification
Range: 0 – $FFFFFF
Units: none
Default: $936747 (603719)
This returns the card part number. The same as the CID ASCII command.
MS{anynode},MI13 Display Enable and Type
Range: 0 – 3
Units: none
Default: 0
0 = No Display output
1 = LCD Display Output
3 = Vacuum Display Output
MS{anynode},MI14 MACRO IC Source of Phase Clock
Range: 0 – 1
Units: none
Default: 1
Default MACRO #1 is the default source of the Phase clock. Setting MI14 = 0, sets MACRO IC #0 as
the source of the Phase clock. Normally the second MACRO IC #1 receives its node information after
MACRO IC #0, so it should be the source of the phase clock. This insures that both MACRO ICs receive
the ring node data before a phase interrupt is generated.
MS{anynode},MI15 Enable MACRO Plcc
Range: 0 - 1
Units: none
Default: 0
MI15 enables and disables the PLCCs running in the 16-Axis MACRO CPU.
MACRO IC Global Channel Status Setup MI-Variables
Each MACRO IC (0 and 1) has its own set of these variables. Therefore, they are accessed through their
MACRO IC. For example, MS0,MI16 accesses MACRO IC 0’s MI16 and MS16,MI16 accesses
MACRO IC 1’s MI16. MACRO IC 1’s variables can be accessed can be accessed through MACRO IC 0
by adding 1000 to the MI variable. For example, MS0,MI1016 accesses MACRO IC 1’s MI16
MS{anynode},MI16 Encoder-Fault Reporting Control
Range: 0 - 1
Units: none
Default: 0
MI16 permits the user to control which type of encoder error is reported back to PMAC in the channel
status flag word for each servo interface channel.
If MI16 is set to 0 (default), then the encoder count-error status bit (bit 8 in the channel hardware status
word) for each encoder channel is copied into bit 8 of the matching node’s status flag word for
transmission back to the PMAC. An encoder count error is reported when both A and B encoder signals
have a transition in the same SCLK hardware sampling cycle.
16-Axis MACRO Station MI-Variable Reference 5
Page 14
16-Axis MACRO CPU Software Reference Manual
If MI16 is set to 1, then the ASIC’s own encoder-loss status bit (bit 7 in the channel hardware status
word) for each encoder channel is copied into bit 8 of the matching node’s status flag word for
transmission back to the PMAC. Note that this reporting function is unrelated to the automatic encoderloss shutdown function using external circuitry that can be enabled with MI7 and reported in MI4.
In order for this encoder-loss detection to work properly, several conditions must apply:
• A B version or newer of the DSPGATE1/2 Servo/MACRO IC must be used (true on boards built
since Spring 1998).
• Differential encoders must be used.
• The A+, A-, B+, and B- encoder signals must be wired into the T, U, V, and W supplemental flag
inputs, respectively, as well as into the regular encoder lines.
• The socketed resistor SIP packs for the encoder channels must be reversed from their factory default
configuration. These SIP packs are installed at the factory so that pin 1 of the pack – marked with a
dot – is installed in pin 1 of the socket – marked with a bold white outline and a square solder pin on
the board. For this encoder-loss to work, the SIP-pack for each encoder must be reversed so that it is
at the opposite end of the socket. The SIP packs are:
Board Encoder 1 Encoder 2 Encoder 3 Encoder 4
ACC-24E2 RP22 RP24 RP22* RP24*
ACC-24E2A RP22 RP24 RP22* RP24*
ACC-24E2S RP19 RP21 RP27 RP29
*Resistor packs on Option 1 top board of 2-board assembly
• MI16 must be set to 1.
If the T, U, V, and W input flags are used for different purposes, such as Hall commutation sensors, or
sub-count information from an analog encoder interpolator, the state of the encoder-loss status bit would
appear random and arbitrary.
The state of the encoder-loss hardware status bit for a channel can be polled with MI927 for the node
mapped to the channel. If it has been set, it can be cleared by writing a 0 value to MI927.
Note:
As long as the socketed resistor pack for an encoder is reversed from the factory
default configuration, the 16-Axis MACRO Station will be able to detect
differential encoder loss and shut down on it, even without wiring the encoder
signals into T, U, V, and W. However, unless the signals are wired into these flag
lines and MI16 is set to 1, the 16-Axis MACRO Station will not be able to notify
PMAC exactly which encoder sustained the loss.
MS{anynode},MI17 Amplifier Fault Disable Control
Range: $00 - $FF
Units: none
Default: $00 (amplifier function enabled for all axes)
This variable controls whether the amplifier input to the machine interface channel mapped to each servo
node by SW1 is used as one of the conditions that creates a node fault to be sent back to the PMAC over
the MACRO ring.
The variable consists of eight bits; each bit controls the disabling of the amplifier fault input for one of the
nodes on the Station. A 0 in the bit specifies that the amplifier fault input is to be used (enabled); a 1 in
the bit specifies that the amplifier fault input is not to be used (disabled). The corresponding bit of MI18
determines the polarity of the input if it is enabled.

13 12 9 8 5 4 1 0
MS{anynode},MI18 Amplifier Fault Polarity
Range: $00 - $FF
Units: none
Default: $00 (low-true fault for all nodes)
This variable controls how the 16-Axis MACRO Station interprets the polarity of the amplifier fault
inputs for each servo node. The variable consists of eight bits; each bit controls the polarity for one of the
servo nodes on the Station. A 0 in a bit specifies a low-true fault (low voltage input means fault); a 1 in a
bit specifies a high-true fault (high voltage input means fault). A bit of MI18 is only used if the
corresponding bit of MI17 is set to 0, enabling the amplifier fault function for that node.
The following table shows the relationship between the bits of MI18 and the servo nodes on the Station:

Global I/O Transfer MI-Variables
MS{anynode},MI19 I/O Data Transfer Period
Range: 0 - 255
Units: Phase Clock Cycles
Default: 0
MI19 controls the data transfer period on a 16-Axis MACRO Station between the MACRO node interface
registers and the I/O registers, as specified by station MI-variables MI20 through MI71, and MI169
through MI172. If MI19 is set to 0, this data transfer is disabled. If MI19 is greater than 0, its value sets
the period in Phase clock cycles (the same as MACRO communications cycles) at which the transfer is
done.
MS{anynode},MI20 Data Transfer Enable Mask
Range: $000000000000 - $FFFFFFFFFFFF
Units: Bits
Default: 0
MI20 controls which of 48 possible data transfer operations are performed at the data transfer period set
by MI19. MI20 is a 48-bit value; each bit controls whether the data transfer specified by one of the
variables MI21 through MI68 is performed. The relationship of MI20 bits to MI21-MI68 transfers is
explained in the following table.

Default: 0
These MI-variables each specify a data transfer (copying) operation that will occur on the 16-Axis
MACRO Station at a rate specified by Station Variable MI19, and enabled by Station variable MI20.
Each variable specifies the address from which the data will be copied (read), and the address to which
the data will be copied (written). These variables are 48-bit values, usually specified as 12 hexadecimal
digits.
The first 24 bits (6 hex digits) specify the address of the register on the 16-Axis MACRO Station from
which the data is to be copied; the second 24 bits (six hex digits) specify the address on the 16-Axis
MACRO Station to which the data is to be copied. In each set of six hex digits, the last four hex digits
specify the actual address. The first two digits (eight bits) specify what portion of the address is to be
used.

For copying data between digital I/O cards with byte-wide data paths (ACC-9E,
10E, 11E, 12E, 14E, 65E, 66E, 67E and 68E) and MACRO nodes, it is generally
better to use MI69 – MI71, and MI169 – MI172.

MACRO IC I/O Transfer MI-Variables
Each MACRO IC (0 and 1) has its own set of these variables. Therefore, they are accessed through their
MACRO IC. For example, MS0,MI69 accesses MACRO IC 0’s MI69 and MS16,MI69 accesses
MACRO IC 1’s MI69. MACRO IC 1’s variables can be accessed can be accessed through MACRO IC 0
by adding 1000 to the MI variable. For example, MS0,MI1069 accesses MACRO IC 1’s MI69.

MS{anynode},MI72-MI89 Output Power-On/Shutdown State
Range: $000000 - $FFFFFF
Units: Individual bit values
Default: $000000
MI72 through MI89 are used to determine the states of the digital outputs for 16-Axis MACRO Station
I/O boards at power-on and on controlled station shutdown due to a ring error condition.
Each of these MI-variables is a 24-bit value controlling 24 consecutively numbered I/O points on a
MACRO I/O board. Each bit controls one I/O point. The least significant bit of the MI-variable controls
the lowest-numbered I/O point; the most significant bit controls the highest-numbered I/O point.
A value of 0 in a bit specifies that the corresponding output is to be turned off at power-on or shutdown; a
value of 1 in a bit specifies that the corresponding output is to be turned on at power-on or shutdown. If
an I/O point has been set up as an input, the value of the bit is not important.

encoder conversion table, at Station registers X:$0010 to X:$002F, corresponding to Station MI-variables
MI120 to MI151, respectively.

MI111 through MI118 (MI11x) specify whether, where, and how absolute position is to be read on the
16-Axis MACRO Station for a motor node (MI11x controls the xth motor node, which usually
corresponds to Motor x on PMAC) and sent back to the PMAC or PMAC2.
If MI11x is set to 0, no power-on/reset absolute position value will be returned to PMAC. If MI11x is set
to a value greater than 0, then when the PMAC requests the absolute position because its Ix10 and/or Ix81
values are set to obtain absolute position through MACRO (sending an auxiliary MS{node},MI920 or
MS{node},MI930 command), the 16-Axis MACRO Station will use MI11x to determine how to read
the absolute position, and report that position back to PMAC as an auxiliary response.

MI11x consists of two parts. The low 16 bits (last four hexadecimal digits) specify the address on the 16axis MACRO Station from which the absolute position information is read. The high eight bits (first two
hexadecimal digits) tell the 16-axis MACRO Station how to interpret the data at that address (the method.

performed, producing an unsigned positive position value. Bit 23 of PMAC’s Ix10 for the motor using
this MACRO node must be the same as Bit 23 of the Station’s MI11x.

Units: Extended 16-Axis MACRO Station Addresses
Default: (dependent on SW1 setting)
MI120 through MI151 form the 32-setup lines of the 16-axis MACRO Station’s Encoder Conversion
Table (ECT). The Encoder Conversion Table on the Station is similar in concept to that of the PMAC or
PMAC2 itself; it is identical in structure to the Encoder Conversion Table of the Turbo PMAC. The 16axis MACRO Station’s table is executed every ring cycle to prepare the feedback data to be sent back to
the PMAC over the MACRO ring, where it will likely be passed through the PMAC’s own table.
The ECT consists of a series of entries with each entry processing one feedback value. An entry in the
ECT can have one, two, or three lines, therefore one, two, or three of these 24-bit MI-variables. Each MIvariable occupies a fixed register in the 16-axis MACRO Station’s memory map. The register addresses
are important, because the results of the ECT are accessed by address.
Table Addresses: The following table shows the Station Y-address for each of the MI-variables in the
table. The processed feedback value for an entry resides in the X-register of the same address as the last
line of the entry. Variable MI10x for the xth motor node on the Station should contain the address of this
X-register for the feedback it wants to send back to PMAC over the MACRO ring.

Digital Incremental Encoder Entries ($0x, $Cx): These two conversion table methods utilize the
incremental encoder registers in the DSPGATE ASICs on the Station. Each method provides a processed
result with the units of (1/32) count – the low five bits are fractional data.
With the $0x method, the fractional data is computed by dividing the Time Since Last Count register by
the Time Between Last Two Counts register. This technique is known as 1/T extension, and is the most
commonly used method. It can be used with a digital incremental encoder connected directly to the
Station
With the $Cx method, the fractional data is always set to zero, which means there is no extension of the
incremental encoder count. This setting is used mainly to verify the effect of one of the 1/T extension, or
the parallel extension of an analog encoder, explained below.
The ‘x’ in the second digit is always 0 in both of these methods.
With either of these conversion methods, the source address in the low 16 bits is that of the starting
register of the machine interface channel. The addresses of the machine interface channels that can be
used, and the ECT entry MI-variables that correspond to them, are shown in the following tables. The
‘m’ is the conversion method, representing ‘0’ (Incremental Encoder-1/T interpolation extension) or ‘C’
(Incremental Encoder-no extension).

Table Entry
These are single-line entries in the table, so the next line (MI-Variable) is the start of the next entry.
Analog Incremental Encoder Entries ($8x, $Fx): These two entries process data from analog sinewave
encoders through a Delta Tau interpolator, providing a high number of position states per line using
fractional count data.
Low Resolution: With the $8x method, the fractional data is computed by reading the five inputs at bits
19-23 of the specified address (USER, W, V, U, and T flag inputs, respectively). This technique is
known as parallel extension and can be used with an analog incremental encoder processed through
accessories for the older Macro Stack Technology. This entry will not be utilized very often since the 16Axis Macro Station is used in backplane mode only.
16-Axis MACRO Station MI-Variable Reference 17
Page 26
16-Axis MACRO CPU Software Reference Manual
High Resolution: With the $Fx method, the table computes the fractional information using the A/Dconverter data from an ACC-51E high-resolution encoder interpolator, producing a value with 4096 states
per line. The entry must read both an encoder channel for the whole number of lines of the encoder, and a
pair of A/D converters to determine the location within the line, mathematically combining the values to
produce a single position value.
Encoder Channel Address: The first line of the three-line entry contains $F in the first hex digit and the
base address of the encoder channel to be read in the last four digits (bits 0 to 15). The following table
shows the possible entries for an ACC-51E in the station.

next higher address. The following table shows the possible settings when the ACC-51E is used.

A/D Bias Term: The third line of the entry contains the bias in the A/D converter values. This line
should contain the value that the A/D converters report when they should ideally report zero. The 16Axis MACRO Station subtracts this value from both A/D readings before calculating the arctangent.
Many users will leave this value at 0, but it is particularly useful to remove the offsets of single-ended
analog encoder signals.
This line is scaled so that the maximum A/D converter reading provides the full value of the 24-bit
register (+/-2
23
). Generally, it is set by reading the A/D converter values directly as 24-bit values,
computing the average value over a cycle or cycles, and entering this value here.
Conversion Result: The result of the conversion is placed in the X-register of the third line of the entry.
Careful attention must be paid to the scaling of this 24-bit result. The least significant bit (Bit 0) of the
result represents 1/4096 of a line of the sine/cosine encoder.

When this data is passed to a PMAC, and it reads this data for servo use with Ix03, Ix04, Ix05, or Ix93, it
expects to find data in units of 1/32 of a count. Therefore, PMAC software regards this format as
producing 128 counts per line. (The fact that the hardware counter used produces 4 counts per line is not
relevant to the actual use of this format; this fact would only be used when reading the actual hardware
counter for debugging purposes.)
Example:
This format is used to interpolate a linear scale with a 40-micron pitch (40µm/line), producing a
resolution of about 10 nanometers (40,000/4096), used as position feedback for a motor. PMAC
considers a count to be 1/128 of a line, yielding a count length of 40/128 = 0.3125 µm. To set user units
of millimeters for the axis, the axis scale factor would be:

ACC-28 Style A/D Entries ($1x, $5x): The A/D feedback entries read from the high 16-bits of the
specified address and shift the data right three bits so that the least significant bit of the processed result in
bit 5. Unlike the parallel feedback methods, this method will not roll over and extend the result.
This data typically comes from an ACC-28E backplane A/D board.
The $1x method processes the information directly, essentially a copying with shift. The $5x integrates
the input value as it copies and shifts it. That is, it reads the input value, shifts it right three bits, adds the
bias term in the second line, and adds this value to the previous processed result.
If the second digit ‘x’ of the entry is ‘0’, the 16-bit source value is treated as a signed quantity; if it is ‘8’,
the 16-bit value is treated as an unsigned quantity. Presently, the only A/D accessory of this format that
can interface to the 16-axis MACRO Station is the ACC-28E, which provides an unsigned value, so $18
and $58 should be used.
The following table shows the entries for ACC-28E backplane converter board ADCs. The ‘m’
represents the conversion method, either ‘1’ or ‘5’.

Parallel Feedback Entries ($2x, $3x, $6x, $7x): The parallel feedback entries read a word from the
address specified in the low 16 bits of the first entry. The four methods in this class are:
• $2x: Y-word parallel, no filtering (2-line entry)
• $3x: Y-word parallel, with filtering (3-line entry)
• $6x: X-word parallel, no filtering (2-line entry)
• $7x: X-word parallel, with filtering (3-line entry)
The second digit in the first line of the entry, represented above by ‘x’, specifies how the parallel data at
the specified address is to be processed. Currently there are 5 valid values of ‘x’:
• x=0: Shift data so that the least significant bit of the source register as specified in the “bits used”
mask word is placed in bit 5 of the processed result.
• x=4: Read the least significant byte from the low byte of the specified address; read the middle byte
from the low byte of the (specified address + 1); read the most significant byte from the low byte of
the (specified address + 2). This is used for feedback brought in through the ACC-14E 48-I/O board.
• x=5: Read the least significant byte from the middle byte of the specified address; read the middle
byte from the middle byte of the (specified address + 1); read the most significant byte from the
middle byte of the (specified address + 2). This is used for feedback brought in through the ACC14E 48-I/O board.
• x=6: Read the least significant byte from the high byte of the specified address; read the middle byte
from the high byte of the (specified address + 1); read the most significant byte from the high byte of
the (specified address + 2). This is used for feedback brought in through the ACC-14E 48-I/O board.
• x=8: Process the data from the source register without any shifting, so the least significant bit of the
source register as specified in the “bits used” mask word is place in bit 0 of the processed result.
Time Base Entries ($4x): A time-base entry performs a scaled digital differentiation of the value in the
source register. It is a two-line entry. The first line contains a ‘4’ in the first hex digit and the address of
the source register in the last four hex digits. Usually, the source register is the result register of an
incremental encoder entry higher in the table (addresses $0020 to $003F).
The second line in the entry is the time-base scale factor. The result value equals 2 * Time-Base-ScaleFactor * (New Source Value - Old Source Value). When this entry is used to synchronize a motion
program to a master encoder, creating an electronic cam function, this scale factor should be set equal to
17
2
/ Real-Time-Input-Frequency, where the RTIF is expressed in counts per millisecond. The program is
then written if the master encoder is always putting out this RTIF.
Triggered Time Base Entries ($9x, $Ax, $Bx): A triggered time-base entry is like a regular time-base
entry, except that it is easy to freeze the time base, then start it exactly on receipt of a trigger that captures
the starting master position or time.
The source register for triggered time base must be the starting (X) address for one of the machine
interface channels on the Station.

In use, the method byte is changed as needed by setting of the MI-variable. It is set to $90 (e.g.
MI129=$908808) before the calculations of the triggered move are started, to freeze the time base. It is
set to $B0 (e.g. MI129=$B08808) after the calculations of the triggered move are finished, to “arm” the
time base for the trigger. When the Table sees the trigger (the capture trigger for the machine interface
channel as defined by MI912 and MI913 for the channel), it automatically sets the method byte to $A0 for
running time base.
The second line in the entry is the time-base scale factor. The result value equals 2 * Time-Base-ScaleFactor * (New Source Value - Old Source Value). When this entry is used to synchronize a motion
program to a master encoder, creating an electronic cam function, this scale factor should be set equal to

in the Table. If the method byte is $E0, the two specified entries are added. If the method byte is $E8,
the second entry is subtracted from the first.
Bits 0-7 of the entry specify the address offset from this entry to the first entry to be used, as a signed 8bit quantity. Bits 8-15 of the entry specify the offset from this entry to the second entry to be used. For
example, MI131 is to be used to subtract the result values with MI121 from that of MI120, the offset to
the first entry is -11 ($F5), and the offset to the second entry is -10 ($F6). Therefore MI131=$E8F6F5.

Range: $000000000000 - $FFFFFFFFFFFF
Units: Extended 16-Axis MACRO Station Y Addresses
Default: $000000000000
MI152 and MI153 permit the use of inputs latched by the phase clock on Station I/O boards. This
function is used to get reliable parallel-data feedback on the 16-Axis MACRO Station. It is useful mainly
on ACC-14E backplane boards.
Note:
Jumper E2 on the ACC-14E backplane board must connect pins 2 and 3 to permit
this function.

MI161 through MI168 (MI16x) on the 16-Axis MACRO Station permit the ‘C’ output channel associated
with the MACRO motor node (MI16x controls the xth motor node, which usually corresponds to Motor x
on PMAC) to put out a specified output frequency, starting immediately on power-on/reset, for the
purposes of creating an excitation signal for an MLDT sensor.

If MI16x is set to 0, this function is not enabled, and the ‘C’ output channel can be used for servo control
functions such as PFM stepper control or direct PWM servo control.
22 16-Axis MACRO Station MI-Variable Reference
Page 31
16-Axis MACRO CPU Software Reference Manual
If MI16x is set to a value greater than 0, then the 24-bit value in MI16x is written automatically to the ‘C’
output register of the machine interface channel associated with the MACRO node upon power-up or
reset of the 16-Axis MACRO Station. In addition, during the normal operation of the node, the value in
the third MACRO register is not copied into the ‘C’ output register.
For the MLDT excitation to work properly, the 16-Axis MACRO Station variable MI916 for the node
must be set for 2 or 3 to get PFM style output from the ‘C’ output channel. MI910 for the node must be
set to 12 to use the timer for the MLDT feedback.
To compute the output frequency as a function of MI16x, the following formula can be used:
Output_Freq (Hz) = PFMCLK_Freq (Hz) * MI16x / 16,777,216
To compute the value of MI16x required to produce a desired output frequency, the following formula
can be used:
MI16x = 16,777,216 * Output_Freq (Hz) / PFMCLK_Freq (Hz)
The PFMCLK frequency is set by MI903 for machine interface channels 1 – 4; by MI907 for machine
interface channels 5 – 8; and by MI993 for machine interface channels 9-10.
MACRO IC I/O Transfer MI-Variables
Each MACRO IC (0 and 1) has its own set of these variables. Therefore, they are accessed through their
MACRO IC. For example MS0,MI169 accesses MACRO IC 0’s MI169and MS16,MI169 accesses
MACRO IC 1’s MI169. MACRO IC 1’s variables can be accessed can be accessed through MACRO IC
0 by adding 1000 to the MI variable. For example MS0,MI1169 accesses MACRO IC 1’s MI169.
MS{anynode},MI169, MI170 I/O-Board 72-Bit Transfer Control

MI69 and MI70 specify the registers used in 72-bit I/O transfers between MACRO node interface
registers and I/O registers on the ACC-9E, 10E, 11E, 12E and 14E I/O boards on a 16-Axis MACRO
Station. They are used only if MI19 is greater than 0.
MI169 and MI170 are 48-bit variables represented as 12 hexadecimal digits. The first six digits specify
the number and address of the 72-bit (1x24 and 3x16) real-time MACRO-node register set to be used.

When this function is active, the 16-axis MACRO Station will copy values from the MACRO command
(input) node registers to the I/O board addresses; it will copy values from the I/O board addresses to the
MACRO feedback (output) node registers. Writing a ‘0’ to a bit of the I/O board enables it as an input,
letting the output pull high. Writing a ‘1’ to a bit of the I/O board enables it as an output and pulls the
output low.
Since most of the Backplane IO accessories are only 48 bits, this variable will waste some IO node space
unless three IO cards are placed at the same address utilizing the low, middle and high bites. If one of the
above transfer variables is utilized (only if one card at the address) the transfers take the low byte of 5
consecutive addresses (starting at the address specified in the low 16 bits of this variable) as well as the
middle byte of first three consecutive addresses. It places the data on a full node that is specified with the
node address in bits 24-39 of this variable
Examples:
Accessory 11E at base address $8800 in the low byte and a 9E at base address $8800 in the middle byte.
MI169=$00C0A0008800 transfers 72-bit I/O between an I/O board set at $8800 and MACRO Node 2

MI171, MI172, and MI173 specify the registers used in 144-bit I/O transfers between MACRO I/O node
interface registers and I/O registers on the ACC-3E, 9E, 10E, 11E, and 12E I/O boards on a 16-axis
MACRO Station. It is only used if MI19 is greater than 0.
The transfer utilizes two consecutive 72-bit X-memory MACRO I/O nodes and 3 48-bit IOGATE I/O ICs
that occupy different bytes (low, middle, and high) of the same base address.
MI171, MI172, and MI173 are 48-bit variables each represented as 12 hexadecimal digits. The first six
digits specify the address of the first 72-bit real-time MACRO-node register sets to be used. The second

MACRO IC I/O Transfer MI-Variables
Each MACRO IC (0 and 1) has its own set of these variables. Therefore, they are access through their
MACRO IC.
MS{anynode},MI198 Direct Read/Write Format and Address
Range: $000000 - $FFFFFF
Units: Modified 16-Axis MACRO Station Addresses
Default: $000000
MI198 controls the address and format of the register to be accessed (read from or written to) with
MI199. This permits the access to any register on the 16-Axis MACRO Station by first assigning a value
to MI198, then either reading MI199 or writing to it.
MI198 is a 24-bit variable that can be expressed as six hexadecimal digits. The low 16 bits, represented
by the last four hex digits, represent the 16-Axis MACRO Station address of the register. The high eight
bits, represented by the first two hex digits, represent the format of that address. The table below shows
the legal entries for the first two digits and the format each represents.
For example, for the host computer to read the contents of the DAC1A register as a signed quantity – the
high 16 bits of Y:$8002 – of the 16-axis MACRO Station through a PMAC board, MI198 would be set to
$6D8002, then MI199 would be read. For a 16-axis MACRO Station with an active node 0, this could be
done with the on-line commands:
MS0, MI198=$6D8002
MS0, MI199
16384
In another example, to read the state of Channel 2’s encoder A input – bit 12 of X:$C008 – through a
PMAC board, MI198 would be set to $8CC008, then MI99 would be read.

MS{anynode},MI199 Direct Read/Write Variable
Range: -8,388,608 – 16,777,215
Units: (dependent on register addressed)
Default: none
MI199 is a variable that can be addressed to any register in the 16-Axis MACRO Station’s memory and
I/O map, in order to read a value directly from that register, or write a value directly to that register. This
permits easy access to any register on the 16-Axis MACRO Station.
The address of the register to be accessed, which part of this register, and how the data is to be
interpreted, is set by MI198. The value of MI198 must be set properly before MI199 can be used to
access the register. For repeated access of the same register with MI199, MI198 only needs to be set
once.
Example:
MS0,MI198=$79C03C ; Set to Y:$C03C,0,24,S (PFM8 command value)
MS0,MI199 ; Request value of this register
0 ; PMAC reports this value
MS0,MI199=65536 ; Set to new value through PMAC
Global MACRO, SERVO IC, I/O Identification and Status MI-Variables
These variables are use to help identify the MACRO, Servo, and I/O boards located in the UBUS rack.
They are similar to the Turbo PMAC I4900 type variables. They are global to the CPU and not a function
of the MACRO IC.

MACRO/SERVO IC 4-Axis Servo IC MI-variables
Each MACRO IC has a set of these variables. Up to two Servo IC are attached to each MACRO IC. The
base addresses of the two Servo ICs are defined by MI179 and MI180. MI179 defines the base address of
the Servo IC that contains channels 1 – 4 and MI180 defines the base address of the Servo IC that
contains channels 5 – 8. MI-variables in the range MI900 to MI909 control multi-channel aspects of the
hardware setup for these two Servo ICs (ACC-24E2x’s).
MS{anynode},MI900 PWM 1-4 Frequency Control
Range: 0 - 32767
Units: PWM Frequency = 117,964.8 kHz / [4*MI900+6]
Default: 6527
PWM Frequency = 117,964.8 / 26114 = 4.5173 kHz
MI900 controls the PWM frequency for 16-Axis MACRO Station machine interface channels 1-4. It
does this by setting the limits of the PWM up-down counter, which increments and decrements at the
PWMCLK frequency of 117,964.8 kHz (117.9648 MHz).
The PWM frequency determines the actual switching frequency of amplifiers connected to any of the 16Axis MACRO Station’s first four machine interface channels with the direct PWM command. It is only
important if the direct PWM command signal format is used.
Generally, MI900 is set to the same value as MI992. If a different PWM frequency is desired for
channels 1 to 4, MI900 should be set so that it is an odd-integer multiple (e.g. 3x, 5x, 7x) of MI992, or
that MI992 is an odd-integer multiple of MI900. This will keep the PWM hardware on channels 1-4 in
synchronization with the software algorithms driven by the PHASE clock.
The maximum value that can be written into the PWM command register without full saturation is
MI900+1 on the positive end and -MI900-2 on the negative end. Generally, the "PWM scale factor" Ix66
for Motor x, which determines the maximum PWM command magnitude, is set to MI900 + 10%.
To set MI900 for a desired PWM frequency, the following formula can be used:
MI900 = (117,964.8 kHz / [4*PWM Freq (kHz)]) - 1 (rounded down)
16-Axis MACRO Station MI-Variable Reference 33
Page 42
16-Axis MACRO CPU Software Reference Manual
Example:
To set a PWM frequency of 10 kHz:
MI900 = (117,964.8 kHz / [4*10 kHz]) - 1 = 2948
To set a PWM frequency of 7.5 kHz:
MI900 = (117,964.8 kHz / [4*7.5 kHz]) - 1 = 3931
MS{anynode},MI903 Hardware Clock Control Channels 1-4
Range: 0 - 4095
Units: MI903 = Encoder SCLK Divider
+ 8 * PFM_CLK Divider
+ 64 * DAC_CLK Divider
+ 512 * ADC_CLK Divider
where:
Encoder SCLK Frequency = 39.3216 MHz / (2 ^ Encoder SCLK Divider)
PFM_CLK Frequency = 39.3216 MHz / (2 ^ PFM_CLK Divider)
DAC_CLK Frequency = 39.3216 MHz / (2 ^ DAC_CLK Divider)
ADC_CLK Frequency = 39.3216 MHz / (2 ^ ADC_CLK Divider)
Default: 2258 = 2 + (8 * 2) + (64 * 3) + (512 * 4)
Encoder SCLK Frequency = 39.3216 MHz / (2 ^ 2) = 9.8304 MHz
PFM_CLK Frequency = 39.3216 MHz / (2 ^ 2) = 9.8304 MHz
DAC_CLK Frequency = 39.3216 MHz / (2 ^ 3) = 4.9152 MHz
ADC_CLK Frequency = 39.3216 MHz / (2 ^ 4) = 2.4576 MHz
MI903 controls the frequency of four hardware clock frequencies – SCLK, PFM_CLK, DAC_CLK, and
ADC_CLK – for channels 1-4 on a 16-Axis MACRO Station (on a 4-axis piggyback board with jumper
E1 connecting 1-2). It is a 12-bit variable consisting of four independent 3-bit controls, one for each of
the clocks. Each of these clock frequencies can be divided down from a starting 39.3216 MHz frequency
by powers of 2, 2
each of these clocks are:
N
, from 1 to 128 times (N=0 to 7). This means that the possible frequency settings for

Very few 16-Axis MACRO Station users will be required to change the setting of MI903 from the default
value.
The encoder sample clock signal SCLK controls how often the 16-Axis MACRO Station's digital
hardware looks at the encoder and flag inputs. The 16-Axis MACRO Station can take at most one count
per SCLK cycle, so the SCLK frequency is the absolute maximum encoder count frequency. SCLK also
controls the signal propagation through the digital delay filters for the encoders and flags; the lower the
SCLK frequency, the greater the noise pulse that can be filtered out. The SCLK frequency should
optimally be set to the lowest value that can accept encoder counts at the maximum possible rate.

The pulse-frequency-modulation clock PFM_CLK controls the PFM circuitry that is commonly used for
stepper drives. The maximum pulse frequency possible is 1/4 of the PFM_CLK frequency. The
PFM_CLK frequency should optimally be set to the lowest value that can generate pulses at the
maximum frequency required.
The DAC_CLK controls the serial data frequency into D/A converters. If these converters are on Delta
Tau-provided accessories, the DAC_CLK setting should be left at the default value.
The ADC_CLK controls the serial data frequency from A/D converters. If these converters are on Delta
Tau-provided accessories, the ADC_CLK setting should be left at the default value.
To determine the clock frequencies set by a given value of MI903, use the following procedure:
1. Divide MI903 by 512 and round down to the nearest integer. This value N1 is the ADC_CLK
divider.
2. Multiply N1 by 512 and subtract the product from MI903 to get MI903'. Divide MI903' by 64 and
round down to the nearest integer. This value N2 is the DAC_CLK divider.
3. Multiply N2 by 64 and subtract the product from MI903' to get MI903''. Divide MI903'' by 8 and
round down to the nearest integer. This value N3 is the PFM_CLK divider.
4. Multiply N3 by 8 and subtract the product from MI903''. The resulting value N4 is the SCLK divider.
Examples:
The maximum encoder count frequency in the application is 800 kHz, so the 1.2288 MHz SCLK
frequency is chosen. A pulse train up to 500 kHz needs to be generated, so the 2.4576 MHz PFM_CLK
frequency is chosen. The default serial DACs and ADCs provided by Delta Tau are used, so the default
DAC_CLK frequency of 4.9152 MHz and the default ADC_CLK frequency of 2.4576 MHz are chosen.
From the table:
SCLK Divider N: 5
PFM_CLK Divider N: 4
DAC_CLK Divider N: 3
ADC_CLK Divider N: 4
MI903 = 5 + (8 * 4) + (64 * 3) + (512 * 4) = 5 + 32 + 192 + 2048 = 2277
MI903 has been set to 3429. What clock frequencies does this set?
N1 = INT (3429/512) = 6 ADC_CLK = 611.44 kHz
MI903' = 3429 - (512*6) = 357
N2 = INT (357/64) = 5 DAC_CLK = 1.2288 MHz
MI903'' = 357 - (64*5) = 37
N3 = INT (37/8) = 4 PFM_CLK = 2.4576 MHz
N4 = 37 - (8*4) = 5 SCLK = 1.2288 MHz

MS{anynode},MI904 PWM 1-4 Deadtime / PFM 1-4 Pulse Width Control
Range: 0 - 255
Units: PWM Deadtime = [16 / PWM_CLK (MHz)] * MI904 = 0.135 µsec * MI904
PFM Pulse Width = [1 / PFM_CLK (MHz)] * MI904
= PFM_CLK_period (µsec) * MI904
Default: 15
PWM Deadtime = 0.135 µsec * 15 = 2.03 µsec
PFM Pulse Width = [1 / 9.8304 MHz] * 15 = 1.526 µsec (with default MI903)
16-Axis MACRO Station MI-Variable Reference 35
Page 44
16-Axis MACRO CPU Software Reference Manual
MI904 controls the deadtime period between top and bottom on-times in the 16-Axis MACRO Station’s
automatic PWM generation for machine interface channels 1-4. In conjunction with MI903, it also
controls the pulse width for the 16-Axis MACRO Station's automatic pulse-frequency modulation
generation for machine interface channels 1-4.
The PWM deadtime, which is the delay between the top signal turning off and the bottom signal turning
on, and vice versa, is specified in units of 16 PWM_CLK cycles. This means that the deadtime can be
specified in increments of 0.135 µsec. The equation for MI904 as a function of PWM deadtime is:
MI904 = Deadtime (µsec) / 0.135 µsec
The PFM pulse width is specified in PFM_CLK cycles, as defined by MI903. The equation for MI904 as
a function of PFM pulse width and PFM_CLK frequency is:
MI904 = PFM_CLK Freq (MHz) / PFM pulse width (µsec)
In PFM pulse generation, the minimum off time between pulses is equal to the pulse width. This means
that the maximum PFM output frequency is
PFM Max_Freq (MHz) = PFM_CLK Freq / (2 * MI904)
Examples:
A PWM deadtime of approximately 1 microsecond is desired:
MI904 ≅ 1 µsec / 0.135 µsec ≅ 7
With a 2.4576 MHz PFM_CLK frequency, a pulse width of 0.4 µsec is desired:
MI904 ≅ 2.4576 MHz * 0.4 µsec ≅ 1

MI905 controls the DAC strobe signal for machine interface channels 1-4. The 24-bit word set by MI905
is shifted out serially on lines DAC_STROB1-4, MSB first, one bit per DAC_CLK cycle starting on the
rising edge of the phase clock. The value in the LSB is held until the next phase clock cycle. ACC24E2A backplane analog axis-interface boards have 18-bit DACs; MI905 should be set to $7FFFC0.

Units: PWM Frequency = 117,964.8 kHz / [4*MI906+6]
Default: 6257
PWM Frequency = 117,964.8 / 26114 = 4.5163 kHz
MI906 controls the PWM frequency for machine interface channels 5-8. It does this by setting the limits
of the PWM up-down counter, which increments and decrements at the PWMCLK frequency of
117,964.8 kHz (117.9648 MHz).
The PWM frequency determines the actual switching frequency of amplifiers connected to any of the 16Axis MACRO Station's first four machine interface channels with the direct PWM command. The value
of MI906 is only important if the direct PWM command signal format is used on channels 5 to 8.

Generally, MI906 is set to the same value as MI992. If a different PWM frequency is desired for
channels 5 to 8, MI906 should be set so that it is an odd-integer multiple (e.g. 3x, 5x, 7x) of MI992, or
that MI992 is an odd-integer multiple of MI906. This will keep the PWM hardware on channels 5-8 in
synchronization with the software algorithms driven by the PHASE clock.
To set MI906 for a desired PWM frequency, the following formula can be used:
MI906 = (117,964.8 kHz / [4*PWM Freq (kHz)]) - 1 (rounded down)
Example:
A 30 kHz PWM frequency is desired for Channels 5-8:
MI906 = (117,964.8 / [4 * 30]) - 1 = 982

MS{anynode},MI909 DAC 5-8 Strobe Word
Range: $000000 - $FFFFFF
Units: Serial Data Stream (MSB first, starting on rising edge of phase clock)
Default: $7FFF00 (for 16-bit DAC data)
MI909 controls the DAC strobe signal for machine interface channels 5-8. The 24-bit word set by MI909
is shifted out serially on the DAC_STROB lines, MSB first, one bit per DAC_CLK cycle starting on the
rising edge of the phase clock. The value in the LSB is held until the next phase clock cycle. ACC24E2A backplane analog axis-interface boards have 18-bit DACs; MI909 should be set to $7FFFC0.

MACRO/SERVO IC Node-Specific Gate Array MI-variables
Each MACRO IC has a set of these node related variables. Up to two Servo IC are attached to each
MACRO IC. The base addresses of the two Servo ICs are defined by MI179 and MI180. MI179 defines
the SERVO IC base address for channels 1 – 4, from it the lower 24 bits (Y:part) of MI181 – MI184 are
generated. MI180 defines the SERVO IC base address for channels 5 – 8, from it the lower 24 bits
(Y:part) of MI185 – MI188 are generated. The lower 24 bits (Y:part) of MI181 – MI188 define the base
address for each of the eight node-specific hardware interface channels. MI-variables MI910 through
MI919 on the 16-Axis MACRO Station control the hardware setup of these channels.
These variables are accessed using the MS station auxiliary read and write commands. The number
immediately after the MS specifies the node number, and therefore the channel number mapped to that
node by the SW1 setting.
MS{node},MI910 Encoder/Timer n Decode Control
Range: 0 - 15
Units: None
Default: 7
MI910 controls how the input signal for the encoder mapped to the specified node is decoded into counts.
As such, this defines the sign and magnitude of a “count”. The following settings may be used to decode
an input signal.
0: Pulse and direction CW
1: x1 quadrature decode CW
2: x2 quadrature decode CW
3: x4 quadrature decode CW
4: Pulse and direction CCW
5: x1 quadrature decode CCW
6: x2 quadrature decode CCW
7: x4 quadrature decode CCW
8: Internal pulse and direction
9: Not used
10: Not used
11: x6 hall format decode CW
12: MLDT pulse timer control
(internal pulse resets timer; external pulse latches timer)
13: Not used
14: Not used
15: x6 hall format decode CCW
16-Axis MACRO Station MI-Variable Reference 39

16-Axis MACRO CPU Software Reference Manual
In any of the quadrature decode modes, PMAC is expecting two input waveforms on CHAn and CHBn,
each with approximately 50% duty cycle, and approximately one-quarter of a cycle out of phase with
each other. “Times-one” (x1) decode provides one count per cycle; x2 provides two counts per cycle; and
x4 provides four counts per cycle. The vast majority of users select x4 decode to get maximum
resolution.
The clockwise (CW) and counterclockwise (CCW) options simply control which direction counts up. If
you get the wrong direction sense, simply change to the other option (e.g. from 7 to 3 or vice versa).
Note:
If you change the direction sense of an encoder with a properly working servo
without also changing the direction sense of the output, you can get destabilizing
positive feedback to your servo and a dangerous runaway condition.
In the pulse-and-direction decode modes, PMAC is expecting the pulse train on CHAn, and the direction
(sign) signal on CHBn. If the signal is unidirectional, the CHBn line can be allowed to pull up to a high
state, or it can be hardwired to a high or low state.
If MI910 is set to 8, the decoder inputs the pulse and direction signal generated by Channel n’s pulse
frequency modulator (PFM) output circuitry. This permits the 16-Axis MACRO Station to create a
phantom closed loop when driving an open-loop stepper system. No jumpers or cables are needed to do
this; the connection is entirely within the ASIC. The counter polarity automatically matches the PFM
output polarity.
If MI910 is set to 12, the timer circuitry is set up to read magnetostrictive linear displacement transducers
TM
(MLDTs) such as Temposonics
. In this mode, the timer is cleared when the PFM circuitry sends out
the excitation pulse to the sensor on PULSEn, and it is latched into the memory-mapped register when the
excitation pulse is received on CHAn.
If MI910 is set to 11 or 15, the channel is set up to accept 3-phase “hall-effect” style inputs on the A, B,
and C inputs, decoding 6 states per cycle.
MS{node},MI911 Position Compare n Channel Select
Range: 0 - 1
Units: None
Default: 0
0: Use channel n encoder counter for position compare function
1: Use first encoder counter on IC (encoder 1 for channels 1 to 4;
encoder 5 for channels 5 to 8) for position compare function
MI911 determines which encoder input that the position compare circuitry for the machine interface
channel mapped to the specified node uses.
When MI911 is set to 0, the channel's position compare register is tied to the channel's own encoder
counter, and the position compare signal appears only on the EQUn output.
When MI911 is set to 1, the channel's position compare register is tied to the first encoder counter on the
ASIC -- Encoder 1 for channels 1-4, Encoder 5 for channels 5-8, or Encoder 9 for channels 9-10 -- and
the position compare signal appears both on EQUn, and combined into the EQU output for the first
channel on the IC (EQU1 or EQU5); executed as a logical OR.
MI911 for the first channel on an ASIC performs no effective function, so is always 1. It cannot be set to
0.

MS{node},MI912 Encoder n Capture Control
Range: 0 - 15
Units: none
Default: 1
This parameter determines which signal or combination of signals, and which polarity, triggers a position
capture of the counter for the encoder mapped to the specified node. If a flag input (home, limit, or user)
is used, MI913 for the node determines which flag. Proper setup of this variable is essential for a
successful home search, which depends on the position-capture function. The following settings may be
used:
0: Immediate capture
1: Capture on Index (CHCn) high
2: Capture on Flag high
3: Capture on (Index high AND Flag high)
4: Immediate capture
5: Capture on Index (CHCn) low
6: Capture on Flag high
7: Capture on (Index low AND Flag high)
8: Immediate capture
9: Capture on Index (CHCn) high
10: Capture on Flag low
11: Capture on (Index high AND Flag low)
12: Immediate capture
13: Capture on Index (CHCn) low
14: Capture on Flag low
15: Capture on (Index low AND Flag low)
The trigger is armed when the position capture register is read. After this, as soon as the 16-Axis
MACRO Station sees that the specified input lines are in the specified states, the trigger will occur -- it is
level-trigger, not edge-triggered.
MS{node},MI913 Capture n Flag Select Control
Range: 0 - 3
Units: none
Default: 0
This parameter determines which of the “Flag” inputs will be used for position capture (if one is used -see MI912):
0: HMFLn (Home Flag n)
1: PLIMn (Positive End Limit Flag n)
2: MLIMn (Negative End Limit Flag n)
3: USERn (User Flag n)
This parameter is typically set to 0 or 3, because in actual use, the LIMn flags create other effects that
usually interfere with what is trying to be accomplished by the position capture. If you wish to capture on
the LIMn flags, you probably will want to disable their normal functions with Ix25, or use a channel n
where none of the flags is used for the normal axis functions.

MS{node},MI914 Encoder n Gated Index Select
Range: 0 - 1
Units: none
0 = Use ungated index for encoder position capture
1 = Use index gated by quadrature channels for position capture
Default: 0
When MI914 is set to 0, the index channel input (CHCn) for the encoder mapped to the specified
MACRO node is passed directly into the position capture circuitry.
When MI914 is set to 1, the encoder index channel input (CHCn) is logically combined with (“gated by”)
the quadrature signals of Encoder n before going to the position capture circuitry. The intent is to get a
“gated index” signal exactly one quadrature state wide. This provides a more accurate and repeatable
capture, and makes the use of the capture function to confirm the proper number of counts per revolution
very straightforward.
In order for the gated index capture to work reliably, the index pulse must reliably span one, but only one,
“high-high” or “low-low” AB quadrature state of the encoder. MI915 allows you to select which of these
two possibilities is used.
MS{node},MI915 Encoder n Index Gate State
Range: 0 - 1
Units: none
0 = Gate index with “high-high” quadrature state (GI = A & B & C)
1 = Gate index with “low-low” quadrature state (GI = A/ & B/ & C)
Default: 0
When using the gated index feature of the 16-Axis MACRO Station for more accurate position capture
(see MI914), MI915 specifies whether the raw index-channel signal for the encoder mapped to the
specified MACRO node is passed through to the position capture signal only on the high-high quadrature
state, or only on the low-low quadrature state. If MI915 is set to 0, it is passed through only on the highhigh state; if MI915 is set to 1, it is passed through only on the “low-low” state.
MS{node},MI916 Output n Mode Select
Range: 0 - 3
Units: none
0 = Outputs A & B are PWM; Output C is PWM
1 = Outputs A & B are DAC; Output C is PWM
2 = Outputs A & B are PWM; Output C is PFM
3 = Outputs A & B are DAC; Output C is PFM
Default: 3
MI916 controls what output formats are used on the command output signal lines for machine interface
channel n. If a three-phase direct PWM command format is desired, MI916 should be set to 0. If signal
outputs for (external) digital-to-analog converters are desired, MI916 should be set to 1 or 3. In this case,
the C output can be used as a supplemental (non-servo) output in either PWM or PFM form. For
example, it can be used to excite an MLDT sensor (e.g. Temposonics
42 16-Axis MACRO Station MI-Variable Reference
TM
) in PFM form.

16-Axis MACRO CPU Software Reference Manual
MS{node},MI917 Output n Invert Control
Range: 0 - 3
Units: none
0 = Do not invert Outputs A & B; Do not invert Output C
1 = Invert Outputs A & B; Do not invert Output C
2 = Do not invert Outputs A & B; Invert Output C
3 = Invert Outputs A & B; Invert Output C
Default: 0
MI917 controls the polarity of the command output signals for Channel n. The default non-inverted
outputs are high true. For PWM signals on Outputs A, B, and C, this means that the transistor-on signal
is high. Delta Tau PWM-input amplifiers, and most other PWM-input amplifiers, expect this noninverted output format. For such a 3-phase motor drive, MI917 should be set to 0.
For PFM signals on Output C, non-inverted means that the pulse-on signal is high (direction polarity is
controlled by MI918). During a change of direction, the direction bit will change synchronously with the
leading edge of the pulse, which in the non-inverted form is the rising edge. If the drive requires a set-up
time on the direction line before the rising edge of the pulse, the pulse output can be inverted so that the
rising edge is the trailing edge, and the pulse width (established by MI904 or MI908) is the set-up time.
For DAC signals on Outputs A and B, non-inverted means that a 1 value to the DAC is high. DACs used
on Delta Tau accessory boards, as well as all other known DACs always expect non-inverted inputs, so
MI917 should always be set to 0 or 2 when using DACs on Channel n.
MS{node},MI918 Output n PFM Direction Signal Invert Control
Range: 0 - 1
Units: none
0 = Do not invert direction signal (+ = low; - = high)
1 = Invert direction signal (- = low; + = high)
Default: 0
MI918 controls the polarity of the direction output signal in the pulse-and-direction format for Channel n.
It is only active if MI916 has been set to 2 or 3 to use Output C as a pulse-frequency-modulated (PFM)
output.
If MI918 is set to the default value of 0, a positive direction command provides a low output; if MI918 is
set to 1, a positive direction command provides a high output.

variable is queried.
When the value of MI920 is queried, the encoder counter for the channel matched to the specified node is
cleared (when the otherwise similar MI930 is queried, the counter is not cleared.)

their relationship to this value.
MS{node},MI922 ADC A Input Value (Read Only)
Range: $000000 - $FFFFFF
Units: Bits of a 24-bit ADC
MI922 reports the value of the serial ADC input register A for the machine interface channel mapped to
the specified MACRO node number. The value is reported as a 24-bit number, even though there are a
maximum of 18 real bits in the register (the most significant bits) and existing hardware provides 12 or 16
bits of true input.
MS{node},MI923 Compare Auto-Increment Value
Range: -8,388,608 - 8,388,607

channel mapped to the specified MACRO node number.
MS{node},MI924 ADC B Input Value (Read Only)
Range: -8,388,608 - 8,388,607
Units: Bits of a 24-bit ADC
MI924 reports the value of the serial ADC input register B for the machine interface channel mapped to
the specified MACRO node number. The value is reported as a 24-bit number, even though there are a
maximum of 18 real bits in the register (the most significant bits) and existing hardware provides 12 or 16
bits of true input.
MS{node},MI925 Compare A Position Value
Range: -8,388,608 - 8,388,607

interface channel mapped to the specified MACRO node number. The units are encoder counts,
referenced to the position at the latest power-on or reset.
MS{node},MI926 Compare B Position Value
Range: -8,388,608 - 8,388,607
Units: Encoder counts
Default: 0
MI926 specifies the value of the ‘B’ compare register of the position compare function for the machine
interface channel mapped to the specified MACRO node number. The units are encoder counts,
referenced to the position at the latest power-on or reset.

MS{node},MI927 Encoder Loss Status Bit
Range: 0 – 1
Units: none
Default: 0
MI927 reports whether the Servo IC on the 16-Axis MACRO Station has detected loss of a differential
encoder signal for the machine interface channel mapped to the specified MACRO node number. It is a
single-bit variable that reports 0 if no loss has been detected, or a 1 if a loss has been detected. It will still
report a value of 1 after a loss has been detected, even if the signal has been recovered, until a zero value
has been written to MI927 to clear the bit.
For this bit to work properly, the A+, A-, B+, and B- encoder inputs must also be wired into the T, U, V,
and W flags for the channel. Also, the resistor pack for the encoder channel must be reversed from the
standard configuration so that pin 1 of the pack (marked with a dot) is at the opposite end from pin 1 of
the socket (marked with a bold outline and square solder pin).
The shutdown function on encoder loss will work as long as the resistor pack has been reversed from
factory default. However, proper reporting of the exactly where the loss occurred requires double wiring
of the encoder into the flags so MI927 can detect the loss.
This encoder-loss status bit for each channel is copied into bit 8 of the flag status word of the matching
MACRO node for reporting back to PMAC if MI16 for the 16-Axis MACRO Station is set to 1.
If the T, U, V, and W flags are used for other purposes, such as Hall commutation sensors, or analogencoder sub-count data, the status of MI927 should be ignored.
MS{node},MI928 Compare-State Write Enable
Range: 0 – 1
Units: none
Default: 0
When MI928 is set to 1, the value of MI929 if forced onto the position-compare output for the channel
associated with the specified node. MI928 is automatically reset to 0 immediately after this occurs.
MS{node},MI929 Compare-Output Initial State
Range: 0 – 1
Units: none
Default: 0
The value of MI929 is forced onto the position-compare output for the channel associated with the
specified node when MI928 is set to 1. After this, each time the channel’s encoder-counter position
matches the value of MI925 or MI926, the output state is toggled.
MS{node},MI930 Absolute Power-On Position (Read Only)
Range: 0 – $FFFFFFFFFFFF
Units: counts
Default:
This variable, when queried, reports the value of the absolute position for the specified MACRO node.
MI11x for the motor node determines what type of feedback device at what address will be read when this
variable is queried.
When the value of MI930 is queried, the encoder counter for the channel matched to the specified node is
not cleared (when the otherwise similar MI920 is queried, the counter is cleared.)

MS{anynode},MI940 ADC1-4 Strobe Word
Range: $000000 - $FFFFFF

MS{anynode},MI975 MACRO IC 0 I/O Node Enable
Range: $0000 - $FFFF
Units: none (individual bits)
Default: $0000
MI975 permits the enabling of MACRO I/O nodes on MACRO IC 0. MI975 is a 16-bit value – bits 0 to
15 – with bit n controlling the enabling of MACRO node n. If the bit is set to 0, the node is disabled; if
the bit is set to 1, the node is enabled. The I/O nodes on the 16-Axis MACRO Station are nodes 2, 3, 6, 7,
10, and 11, which can be enabled by MI975 bits of these numbers. Only bits 2, 3, 6, 7, 10, and 11 of
MI975 should ever be set to 1.

MI975 is used at the power-on/reset of the 16-Axis MACRO Station in combination with rotary switch
SW1 and MI976 to determine which MACRO nodes are to be enabled. The net result can be read in
Station variable MI996. To get a value of MI975 to take effect, the value must be saved

MS{anynode},MI976 MACRO IC 0 Motor Node Disable
Range: $0000 - $FFFF
Units: none (individual bits)
Default: $0000
MI976 permits the disabling of MACRO IC 0 motor nodes that would be enabled by the setting of rotary
switch SW1. MI976 is a 16-bit value – bits 0 to 15 – with bit n controlling the disabling of MACRO node
n. If the bit is set to 0, the node may be enabled by SW1; if the bit is set to 1, the node is disabled,
regardless of the setting of SW1. The motor nodes on the 16-Axis MACRO Station are nodes 0, 1, 4, 5,
8, 9, 12, and 13, which can be disabled by MI976 bits of these numbers. Only bits 0, 1, 4, 5, 8, 9, 12, &

MI976 is used at the power-on/reset of the 16-Axis MACRO Station in combination with rotary switch

MS{anynode},MI977 Motor Nodes Reporting Ring Break
Range: $0000 - $FFFF
Units: none (individual bits)
Default: $0
MI977 permits the 16-Axis MACRO Station to enable additional motor nodes if it detects a ring break
immediately upstream from it, and send out the “ring break” bit (Bit 13) in the flag word for these nodes.
When the Station detects a ring break, it turns itself into a ring controlling master, and sets the “ring
break” bit on all active nodes. In this manner, other stations downstream of the break can be directly
notified of the ring break, so they can shut down properly.

MI977 is a 16-bit value – bits 0 to 15 – with bit n controlling the enabling of MACRO node n on a ring
break If the bit is set to 0, the node will not be enabled on a ring break; if the bit is set to 1, the node will
be enabled on a ring break. The motor nodes on the 16-Axis MACRO Station are nodes 0, 1, 4, 5, 8, 9,

MI987 controls whether the 16-Axis MACRO Station will read an A/D backplane board). If MI987 is set

each of the Y-registers $0200 to $0207 for MACRO IC 0 and &208 to $20F for MACRO IC 1. If MI987

MI988 controls whether the 12-bit A/D converters are set up for unipolar (0 to +20V) or bipolar (-10 to
+10V) inputs. MI988 consists of 8 bits; each bit controls the setup of a pair of A/D converters. A value
of 0 in the bit sets up the A/D converters for unipolar inputs; a value of 1 in the bits sets up the A/D
converters for bipolar inputs.

This variable specifies the source address of the multiplexed A/D converters acted on by the demultiplexing algorithms of MI987 and MI988. These multiplexed A/D converters can be on ACC-36E or
ACC-59E backplane boards.
The A/D converters on an ACC-36E or ACC-59E backplane board are located at 1 of 16 addresses,
depending on the DIP-switch setting of the board ($8800,$8840,$8880,$88C0,
$9800,$9840,$9880,$98C0, $A800,$A840,$A880,$A8C0, $B800,$B840,$B880,$B8C0)
Example: MS0,MI989=$9800 implies that MACRO16 CPU will perform 12-bit ADC operations on the
Accessory card loacated at $9800.
MACRO IC MI-Variables
MI-Variables numbered in the MI990s control hardware aspects of the MACRO IC and the handwheel
channels 1 and 2. Each MACRO IC has its own set of these variables.
MS{anynode},MI992 MaxPhase Frequency Control
Range: 0 - 32767
Units: MaxPhase Frequency = 117,964.8 kHz / [2*MI992+3]
PWM Frequency = 117,964.8 kHz / [4*MI992+6]
Default: 6527
MaxPhase Frequency = 117,964.8 / 13057 = 9.0346 kHz
PWM Frequency = 117,964.8 / 26114 = 4.5173 kHz
MI992 controls the "maximum phase" clock frequency for the 16-Axis MACRO Station, and the PWM
frequency for supplementary handwheel interface channels 1 and 2. It does this by setting the limits of
the PWM up-down counter, which increments and decrements at the PWMCLK frequency of 117,964.8
kHz (117.9648 MHz).
The actual phase clock frequency is divided down from the maximum phase clock according to the setting
of MI997. The phase clock frequency must be the same as the ring update frequency as set by the ring
controller - usually a PMAC or PMAC2. If the ring controller is a PMAC2 Ultralite, MI992 and MI997
on the 16-Axis MACRO Station should be set to the same values as MI992 and MI997 on the PMAC2
Ultralite.
To set MI992 for a desired "maximum phase" clock frequency, the following formula can be used:
MI992 = (117,964.8 kHz / [2*MaxPhase (kHz)]) - 1 (rounded down)
Examples:
To set a PWM frequency of 10 kHz and therefore a MaxPhase clock frequency of 20 kHz:
MI992 = (117,964.8 kHz / [4*10 kHz]) - 1 = 2948
To set a PWM frequency of 7.5 kHz and therefore a MaxPhase clock frequency of 15 kHz:
MI992 = (117,964.8 kHz / [4*7.5 kHz]) - 1 = 3931
MS{anynode},MI993 Hardware Clock Control Handwheel Channels
Range: 0 - 4095
Units: MI993 = Encoder SCLK Divider
+ 8 * PFM_CLK Divider
+ 64 * DAC_CLK Divider
+ 512 * ADC_CLK Divider
where:
Encoder SCLK Frequency = 39.3216 MHz / (2 ^ Encoder SCLK Divider)
PFM_CLK Frequency = 39.3216 MHz / (2 ^ PFM_CLK Divider)
DAC_CLK Frequency = 39.3216 MHz / (2 ^ DAC_CLK Divider)
50 16-Axis MACRO Station MI-Variable Reference
Page 59
16-Axis MACRO CPU Software Reference Manual
ADC_CLK Frequency = 39.3216 MHz / (2 ^ ADC_CLK Divider)
Default: 2258 = 2 + (8 * 2) + (64 * 3) + (512 * 4)
Encoder SCLK Frequency = 39.3216 MHz / (2 ^ 2) = 9.8304 MHz
PFM_CLK Frequency = 39.3216 MHz / (2 ^ 2) = 9.8304 MHz
DAC_CLK Frequency = 39.3216 MHz / (2 ^ 3) = 4.9152 MHz
ADC_CLK Frequency = 39.3216 MHz / (2 ^ 4) = 2.4576 MHz
MI993 controls the frequency of three hardware clock frequencies -- SCLK, PFM_CLK, DAC_CLK and
ADC_CLK -- for the handwheel interface channels 1 and 2. It is a 12-bit variable consisting of four
independent 3-bit controls, one for each of the clocks. Each of these clock frequencies can be divided
down from a starting 39.3216 MHz frequency by powers of 2, 2
N
, from 1 to 128 times (N=0 to 7). This
means that the possible frequency settings for each of these clocks are:
Frequency Divide by Divider N in
1/2N
39.3216 MHz 1 0
19.6608 MHz 2 1
9.8304 MHz 4 2
4.9152 MHz 8 3
2.4576 MHz 16 4
1.2288 MHz 32 5
611.44 kHz 64 6
305.72 kHz 128 7
Very few 16-Axis MACRO Station users will be required to change the setting of MI993 from the default
value.
The encoder sample clock signal SCLK controls how often 2-axis board’s digital hardware looks at the
encoder inputs. PMAC2 can take at most one count per SCLK cycle, so the SCLK frequency is the
absolute maximum encoder count frequency. SCLK also controls the signal propagation through the
digital delay filters for the encoders and flags; the lower the SCLK frequency, the greater the noise pulse
that can be filtered out. The SCLK frequency should optimally be set to the lowest value that can accept
encoder counts at the maximum possible rate.
The pulse-frequency-modulation clock PFM_CLK controls the PFM circuitry on the 2-axis board that can
create pulse and direction outputs. The maximum pulse frequency possible is 1/4 of the PFM_CLK
frequency. The PFM_CLK frequency should optimally be set to the lowest value that can generate pulses
at the maximum frequency required.
The ADC_CLK controls the serial data frequency from A/D converters, either for digital current loop
closure, or from an ACC-28B A/D converter board.
The DAC-CLK controls the serial data frequency to D/A converters for the 2-axis board, either the onboard converters that come with Option A, or the external converters on an ACC-8E board.
To determine the clock frequencies set by a given value of MI993, use the following procedure:
1. Divide MI993 by 512 and round down to the nearest integer. This value N1 is the ADC_CLK
divider.
2. Multiply N1 by 512 and subtract the product from MI993 to get MI993'. Divide MI993' by 64 and
round down to the nearest integer. This value N2 is the DAC_CLK divider (not relevant here).
3. Multiply N2 by 64 and subtract the product from MI993' to get MI993''. Divide MI993'' by 8 and
round down to the nearest integer. This value N3 is the PFM_CLK divider.
4. Multiply N3 by 8 and subtract the product from MI993''. The resulting value N4 is the SCLK divider.

Examples:
The maximum encoder count frequency in the application is 800 kHz, so the 1.2288 MHz SCLK
frequency is chosen. A pulse train up to 500 kHz needs to be generated, so the 2.4576 MHz PFM_CLK
frequency is chosen. ADCs and DACs are not used, so the default DAC_CLK frequency of 4.9152 MHz
and the default ADC_CLK frequency of 2.4576 MHz are chosen. From the table:
SCLK Divider N: 5
PFM_CLK Divider N: 4
DAC_CLK Divider N: 3
ADC_CLK Divider N: 4
MI993 = 5 + (8 * 4) + (64 * 3) + (512 * 4) = 5 + 32 + 192 + 2048 = 2277
MI993 has been set to 3429. What clock frequencies does this set?
N1 = INT (3429/512) = 6 ADC_CLK = 611.44 kHz
MI993' = 3429 - (512*6) = 357
N2 = INT (357/64) = 5 DAC_CLK = 1.2288 MHz
MI993'' = 357 - (64*5) = 37
N3 = INT (37/8) = 4 PFM_CLK = 2.4576 MHz
N4 = 37 - (8*4) = 5 SCLK = 1.2288 MHz
MS{anynode},MI994 PWM Deadtime / PFM Pulse Width Control for
Handwheel
Range: 0 - 255
Units: PWM Deadtime = [16 / PWM_CLK (MHz)] * MI994 = 0.135 µsec * MI994
PFM Pulse Width = [1 / PFM_CLK (MHz)] * MI994
= PFM_CLK_period (µsec) * MI994
Default: 15
PWM Deadtime = 0.135 µsec * 15 = 2.03 µsec
PFM Pulse Width = [1 / 9.8304 MHz] * 15 = 1.526 µsec (with default MI993)
MI994 controls the deadtime period between top and bottom on-times in the 16-Axis MACRO Station’s
automatic PWM generation for machine interface handwheel channels 19 and 2. In conjunction with
MI993, it also controls the pulse width for PMAC2’s automatic pulse-frequency modulation generation
for these machine interface channels.
The PWM deadtime, which is the delay between the top signal turning off and the bottom signal turning
on and vice versa, is specified in units of 16 PWM_CLK cycles. This means that the deadtime can be
specified in increments of 0.135 µsec. The equation for MI994 as a function of PWM deadtime is:
MI994 = Deadtime (µsec) / 0.135 µsec
The PFM pulse width is specified in PFM_CLK cycles, as defined by MI993. The equation for MI994 as
a function of PFM pulse width and PFM_CLK frequency is:
MI994 = PFM_CLK Freq (MHz) / PFM pulse width (µsec)
In PFM pulse generation, the minimum off time between pulses is equal to the pulse width. This means
that the maximum PFM output frequency is
PFM Max_Freq (MHz) = PFM_CLK Freq / (2 * MI994)
Examples:
A PWM deadtime of approximately 1 microsecond is desired:
MI994 ≅ 1 µsec / 0.135 µsec ≅ 7
With a 2.4576 MHz PFM_CLK frequency, a pulse width of 0.4 µsec is desired:
MI994 ≅ 2.4576 MHz * 0.4 µsec ≅ 1

MS{anynode},MI995 MACRO Ring Configuration/Status
Range: $0000 - $FFFF (0 - 65,535)
Units: none

MI995 contains configuration and status bits for MACRO ring operation of the 16-Axis MACRO Station.
There are 11 configuration bits and 5 status bits, as follows:

14 16384($4000) Config Node 14 Master Address Check Disable
15 32768($8000) Config Node 15 Master Address Check Disable
A 16-Axis MACRO Station is a slave on the ring in all normal operation, so configuration bits 4 and 5 are
set to 0. It should synchronize itself to the sync node, so configuration bit 7 should be set to 1. In most
applications, it will only accept packets from its own master so bits 8 to 15 are all set to 0. All other bits
are status bits that are normally 0. This makes the usual setting of MI995 equal to $0080.
MS{anynode},MI996 MACRO Node Activate Control
Range: $000000 to $FFFFFF (0 to 8,388,607)
Units: none
Default: $0 – See SW1 table.
MI996 controls which of the 16 MACRO nodes on the 16-Axis MACRO Station are activated. It also
controls the master station number, and the node number of the packet that creates a synchronization
signal.
On a power-up or reset of the 16-Axis MACRO Station, MI996 for MACRO IC 0 is set automatically by
Station firmware as a function of SW1 and SW2 switch settings, plus the saved values of MI975 and
MI976.

16-19 $X0000 Config Packet Sync Node Slave Address (0 - 15)
20-23 $X00000 Config Master Station Number (0-15)
Bits 0 to 15 are individual control bits for the matching node number 0 to 15. If the bit is set to 1, the
node is activated; if the bit is set to 0, the node is de-activated. On power-up reset, these bits are set as
defined by the SW1 setting, with some motor nodes possibly disabled by MI976, and some I/O nodes
possibly enabled by MI975. Node 15 should always be activated to support the Type 1 auxiliary
communications.
Bits 16-19 specify the slave number of the packet which will generate the “sync pulse” on the 16-Axis
MACRO Station. This is always set to 15 ($F) on the 16-Axis MACRO Station.
Bits 20-23 specify the master number (0-15) for the 16-Axis MACRO Station. At power-up/reset, these
bits get the value set by SW2. The number must be specified whether the card is a master station or a
slave station.

MS{anynode},MI997 Phase Clock Frequency Control
Range: 0 - 15
Units: PHASE Clock Frequency = MaxPhase Frequency / (MI997+1)
Default: 0
PHASE Clock Frequency = 9.0346 kHz / 1 = 9.0346 kHz
(with default value of MI992)
MI997, in conjunction with MI992, determines the frequency of the PHASE clock on a 16-Axis MACRO
Station. Each cycle of the PHASE clock, a set of MACRO ring information is expected, and any data
transfers between MACRO nodes and interface circuitry are performed. The PHASE clock cycle on the
16-Axis MACRO Station should match that of the PMAC commanding it as closely as possible.
Specifically, MI997 controls how many times the PHASE clock frequency is divided down from the
"maximum phase" clock, whose frequency is set by MI992. The PHASE clock frequency is equal to the
"maximum phase" clock frequency divided by (MI997+1). MI997 has a range of 0 to 15, so the
frequency division can be by a factor of 1 to 16. The equation for MI997 is:
MI997 = (MaxPhase Freq / PHASE Clock Freq) - 1
The ratio of MaxPhase Freq. to PHASE Clock Freq. must be an integer.
Example:
With a 20 kHz MaxPhase Clock frequency established by MI992, and a desired 6.67 kHz PHASE clock
frequency, the ratio between MaxPhase and PHASE is 3:
MI997 = (20 / 6.67) - 1 = 3 -1 = 2
MS{anynode},MI998 Servo Clock Frequency Control
Range: 0 - 15
Units: Servo Clock Frequency = PHASE Clock Frequency / (MI998+1)
Default: 0
PHASE Clock Frequency = 9.0346 kHz / (0+1) = 9.0346 kHz
(with default values of MI992 and MI997)
Note:
There is currently no software use of the SERVO clock on the 16-Axis MACRO
Station. However, it is needed to capture certain encoder values in the
DSPGATEx Servo ICs.
MI998, in conjunction with MI997 and MI992, determines the frequency of the SERVO clock on the 16Axis MACRO Station.
Specifically, MI998 controls how many times the SERVO clock frequency is divided down from the
PHASE clock, whose frequency is set by MI992 and MI997. The SERVO clock frequency is equal to the
PHASE clock frequency divided by (MI998+1). MI998 has a range of 0 to 15, so the frequency division
can be by a factor of 1 to 16. The equation for MI998 is:
MI998 = (PHASE Clock Freq. / SERVO Clock Freq) - 1
The ratio of PHASE Clock Freq. to SERVO Clock Freq. must be an integer. On the 16-Axis MACRO
Station, MI998 should always be set to 0 so the servo clock frequency is equal to the phase clock
frequency.

16-AXIS MACRO CPU STATION SERIAL COMMANDS
The 16-Axis MACRO Station can accept ASCII text commands directly through the serial port at
connector J7 on the CPU/Interface Board, or in auxiliary mode from a Turbo PMAC over the MACRO
ring using MACSTASCII commands. Serial communications is at 9600 baud (CPU board jumper E3
connecting pins 1 and 2) or 38400 baud (E3 connecting pins 2 and 3), eight bits, one stop bit, no parity.
These commands are intended for basic setup and troubleshooting. Most users will not utilize this port,
instead sending commands only through the MACRO ring.
The following commands can be sent to the 16-Axis MACRO Station through the serial port or over the
MACRO ring.
$$$ Station Reset
The $$$ command will reset the 16-Axis MACRO Station and restore all station MI-variables to their
last saved values.
$$$*** Station Re-initialize
The $$$*** command will reset the 16-Axis MACRO Station and restore all station MI-variables to
their factory default values.

The CID command causes the 16-Axis MACRO Station CPU to report its part number: 602804.
CLRF Clear Station Faults
The CLRF command will clear all faults on the 16-Axis MACRO Station and prepare it for further
operation.

TURBO PMAC TYPE 1 16-AXIS MACRO CPU STATION
COMMANDS
The following commands from the Turbo PMAC controllers can be used for Type 1 auxiliary
communication with the 16-Axis MACRO Station.
On-Line Commands
MS Command
Syntax: MS{command}{node #}
where:
{command} is one of the following text strings:
$$$ normal station reset
$$$*** station reset and re-initialize
CLRF station fault clear for
CONFIG report station configuration value
DATE report station firmware date
SAVE save station setup
VER report station firmware version
{node #} is a constant representing the number of the node to be commanded (if the
command affects the entire station, the number of any active node on the
station may be used)
This PMAC command causes PMAC to issue the specified command to a Type 1 MACRO slave station.
The MS CONFIG command allows the user to set and report a user-specified configuration value. This
provides any easy way for the user to see if the 16-Axis MACRO Station has already been configured to
the user’s specifications. The factory default configuration value is 0. It is recommended that after the
user finishes the software configuration of the station, a special number be given to the configuration
value with the MS CONFIG{node #}={constant} command. This number will be saved to the non-
volatile memory with the MS SAVE command. Subsequently, when the system is powered up, the station
can be polled with the MS CONFIG {node #} command. If the expected value is returned, the station
can be assumed to have the proper software setup. If the expected value is not returned (for instance,
when a replacement station has just been installed) then the setup will have to be transmitted to the
station.
Examples:
MS $$$0 ; Resets 16-Axis MACRO Station which has active node 0
MS $$$***4 ; Reinitializes 16-Axis MACRO Station which has active node 4
MS CLRF8 ; Clears fault on Node 8 of 16-Axis MACRO Station
MS CONFIG12 ; Causes 16-Axis MACRO Station to report its configuration number
37 ; PMAC reports 16-Axis MACRO Station configuration number to host
MS CONFIG12=37 ; Sets 16-Axis MACRO Station configuration number
MS DATE 0 ; Causes 16-Axis MACRO Station to report its firmware date
03/27/97 ; PMAC reports 16-Axis MACRO Station firmware date to host
MS SAVE 4 ; Causes 16-Axis MACRO Station to save setup variables
MS VER 8 ; Causes 16-Axis MACRO Station to report its firmware version
1.200 ; PMAC reports 16-Axis MACRO Station firmware version to host
Turbo PMAC Type 1 16-Axis MACRO Station Commands 67
Page 76
16-Axis MACRO CPU Software Reference Manual
MS Variable Read
Syntax: MACROSLAVE{node #},{slave MI, MM or MP variable}
MS{node #},{slave MI-variable}
where:
{node #} is a constant (0-14) representing the number of the node whose
variable is to be read (if the variable is not node-specific,
the number of any active node on the station may be used)
{slave MI, MM or MP -variable} is the name of the MI, MM or
MP-variable on the slave station whose value is to be reported
This command causes PMAC to query the MACRO slave station at the specified node # and report back
the value of the specified slave station MI-variable to the host computer.
Examples:
MS0,MI910 ; Causes 16-Axis MACRO Station to report value of Node 0
; variable MI910
7 ; PMAC reports this value back to host
MS1,MI997 ; Causes 16-Axis MACRO Station to report value global variable MI997
6258 ; PMAC reports this value back to host
MS1,MM1 ; Causes 16-Axis MACRO Station to report value global variable MM1
8 ; PMAC reports this value back to host
MS Variable Write
Syntax: MACROSLAVE{node #},{slave variable}={constant}
MS{node #},{slave variable}={constant}
where:
{node #} is a constant (0-14) representing the number of the node whose
variable is to be written to (if the variable is not node-specific, the
number of any active node on the station may be use)
{slave MI, MM or MP -variable} is the name of the MI, MM,
MP or C -variable on the slave station whose value is to be reported
{constant} is a number representing the value to be written to the
specified MI, MM or MP -variable
This command causes PMAC to write the specified constant value to the MACRO slave station MI, MM,
MP -variable, or if a C-command is specified, it causes the station to execute the specified command
number (in which case the constant value does not matter).
The valid C-commands are:
• C1 Clear station faults
• C2 Reset station, loading saved station MI-variables
• C3 Re-initialize station, loading default station MI-variables
• C4 Save station MI-variables to non-volatile memory
Examples:
MS0,MI910=7 ;sets Node 0 variable MI910 to 7
MS8,C4=0 ;Clears faults on 16-Axis MACRO Station with active node 8
MS0,MM1=7 ;sets global variable MM1 to 7

MACRO UBUS Port I/O Registers
Note:
Presently, ACC-9E, 10E, 11E, and 12E boards make no distinction between A, B,
C, and D base addresses, because they do not use address lines A13 and A12.. If
one of these boards is set up for a certain base address 0, 2, 4, or 6, it will respond
to any of the four possible settings for this address (A, B, C, or D), and no other
board may be placed at any of the settings for this numerical base address.
