Turbo PMAC PCI Lite

ICs U140, U143, and U147 are
installed in the Turbo version of the
PMAC Lite PCI board.

INTRODUCTION

The Turbo PMAC PCI Lite is a member of the Turbo PMAC family of boards optimized for interface to
traditional servo drives with single analog inputs representing velocity or torque commands. Its software
is capable of 32 axes of control. It can have up to four channels of on-board axis interface circuitry. It
can also support up to 32 channels of off-board axis interface circuitry through its expansion port,
connected to Acc-24P or Acc-24P2 boards.

The Turbo PMAC PCI Lite is a full-sized PCI-bus expansion card. While the Turbo PMAC PCI Lite is
capable of PCI bus communications, with or without the optional dual-ported RAM, it does not need to be
inserted into a PCI expansion slot. Communications can be done through an RS-232 or RS-422 serial
port. Standalone operation is possible.

The same circuit board with some ICs not installed produces a (non-Turbo) PMAC PCI Lite controller.
The above diagram shows the key components installed in the Turbo configuration only.

Option 2: Dual-Ported RAM

Dual-ported RAM provides a very high-speed communications path for bus communications with the
host computer through a bank of shared memory. DPRAM is advised if more than 100 data items per
second are to be passed between the controller and the host computer in either direction.

Option 2 provides an 8k x 16 bank of dual-ported RAM in component. The key component on the

board is U1.

Introduction 1

Turbo PMAC PCI Lite

Option 5: CPU and Memory Configurations

The various versions of Option 5 provide different CPU speeds and main memory sizes integrated on the
main board. Only one Option 5xx may be selected for the board.

The CPU is a DSP563x IC as component U127. The CPU is available in different speeds and with
different internal memory sizes.

The compiled/assembled-program memory SRAM ICs are located in U141, U144 and U148. These ICs
form the active memory for the firmware, compiled PLCs, and user-written phase/servo algorithms.
These can be 128k x 8 ICs (for a 128k x 24 bank), fitting in the smaller footprint, or they can be the larger
512k x 8 ICs (for a 512k x 24 bank), fitting in the full footprint.

The user-data memory SRAM ICs are located in U140, U143, and U147. These ICs form the active
memory for user motion programs, uncompiled PLC programs, and user tables and buffers. These can be
128k x 8 ICs (for a 128k x 24 bank), fitting in the smaller footprint, or they can be the larger 512k x 8 ICs
(for a 512k x 24 bank), fitting in the full footprint.

The flash memory IC is located in U146. This IC forms the non-volatile memory for the board’s
firmware, the user setup variables, and for user programs, tables, and buffers. It can be 1M x 8, 2M x 8,
or 4M x 8 in capacity.

Option 5C0 is the standard CPU and memory configuration. It is provided automatically if no Option

5xx is specified. It provides an 80 MHz DSP56303 CPU (120 MHz PMAC equivalent), 128k x24 of
compiled/assembled program memory, 128k x 24 of user data memory and a 1M x 8 flash memory.

Option 5C3 provides an 80 MHz DSP56303 CPU (120 MHz PMAC equivalent) with 8k x 24 of

internal memory, an expanded 512k x 24 of compiled/assembled program memory, an expanded 512k
x 24 of user data memory, and a 4M x 8 flash memory.

Option 5E0 provides a 160 MHz DSP56311 CPU (240 MHz PMAC equivalent) with 128k x 24 of

internal memory, 128k x 24 of compiled/assembled program memory, 128k x 24 of user data memory
and a 1M x 8 flash memory.

Option 5E3 provides a 160 MHz DSP56311 CPU (240 MHz PMAC equivalent) with 128k x 24 of

internal memory, 512k x 24 of compiled/assembled program memory, 512k x 24 of user data memory
and a 4M x 8 flash memory.

Option 8: High-Accuracy Clock Crystal

The Turbo PMAC PCI Lite has a clock crystal (component Y1) of nominal frequency 19.6608 MHz (~20
MHz). The standard crystal’s accuracy specification is +/-100 ppm.

Option 8A provides a nominal 19.6608 MHz crystal with a +/-15 ppm accuracy specification.

Option 9T: Auxiliary Serial Port

Option 9T adds an auxiliary RS-232 port on the CPU piggyback board. The key components added are
IC U22 and connector J8 on the CPU board.

Option 10: Firmware Version Specification

Normally the Turbo PMAC PCI Lite is provided with the newest released firmware version. A label on
the U146 flash memory IC shows the firmware version loaded at the factory.

Option 10 provides for a user-specified firmware version.

Option 12: Analog-to-Digital Converters

Option 12 permits the installation of 8 or 16 channels of on-board multiplexed analog-to-digital
converters. One or two of these converters are read every phase interrupt. The analog inputs are not
optically isolated and each can have a 0 – 5V input range, or a +/-2.5V input range, individually
selectable.

2 Introduction

Turbo PMAC PCI Lite

Option 12 provides an 8-channel 12-bit A/D converter. The key components on the board are U20

and connector J30.

Option 12A provides an additional 8-channel 12-bit A/D converter. The key component on the board

is U22.

Option 15: V-to-F Converter for Analog Input

The JPAN control panel port on the Turbo PMAC PCI Lite has an optional analog input called Wiper

(because it is often tied to a potentiometer’s wiper pin). Turbo PMAC PCI Lite can digitize this signal by

passing it through an optional voltage-to-frequency converter, using E-point jumpers to feed this into the
Encoder 4 circuitry (no other use is then permitted), and executing frequency calculations using the time
base feature of the encoder conversion table.

Option 15 provides a voltage-to-frequency converter in component U18 that permits the use of the

Wiper input on the control panel port.

Option 16: Battery-Backed Para meter Memory

The contents of the standard memory are not retained through a power-down or reset unless they have
been saved to flash memory first. Option 16 provides supplemental battery-backed RAM for real-time
parameter storage that is ideal for holding machine state parameters in case of an unexpected power­down. The battery is located at component BT1.

Option 16A provides a 32k x 24 bank of battery-backed parameter RAM in components U142, U145,

and U149, fitting in the smaller footprint for those locations.

Option 18: Identification Number & Real-Time Clock/Calendar Module

Option 18 provides a module that contains an electronic identification number, and possibly a real-time
clock/calendar.

Option 18A provides an electronic identification number module.

HARDWARE SETUP

On the PMAC, there are many jumpers (pairs of metal prongs), called E-points. Some have been shorted
together; others have been left open. These jumpers customize the hardware features of the board for a
given application and must be setup appropriately. The following is an overview of the several PMAC
jumpers grouped in appropriate categories. For a complete description of the jumper setup configuration,
refer to the Turbo PMAC PCI Lite E-Point Jumper Descriptions section of this manual.

Power-Supply Configuration Jumpers

E85, E87, E88: Analog Circuit Isolation Control – These jumpers control whether the analog circuitry
on the PMAC is isolated from the digital circuitry, or electrically tied to it. In the default configuration,
these jumpers are off, keeping the circuits isolated from each other (provided separate isolated supplies
are used).

E89-E90: Input Flag Supply Control – If E90 connects pins 1 and 2 and E89 is ON, the input flags
(+LIMn, -LIMn, HMFLn, and FAULTn) are supplied from the analog A+15V supply, which can be
isolated from the digital circuitry. If E90 connects pins 1 and 2 and E89 is OFF, the input flags are
supplied from a separate A+V supply through pin 9 of the J9 JEQU connector. This supply can be in the
+12V to +24V range and can be kept isolated from the digital circuitry. If E90 connects pins 2 and 3, the
input flags are supplied from the digital +12V supply and isolation from the digital circuitry is defeated.

E100: AENA/EQU Supply Control – If E100 connects pins 1 and 2, the circuits related to the AENAn,
EQUn, and FAULTn signals will be supplied from the analog A+15V supply, which can be isolated from
the digital circuitry. If E100 connects pins 2 and 3, the circuits will be supplied from a separate A+V
supply brought in on pin 9 of the J9 JEQU connector. This supply can be in the +12V to +24V range, and
can be kept isolated from the digital circuitry.

4 Hardware Setup

Turbo PMAC PCI Lite

Clock Configuration Jumpers

E3-E6: Servo Clock Frequency Control – The jumpers E3 – E6 determine the servo-clock frequency by
controlling how many times it is divided down from the phase-frequency. The default setting of E3 and
E4 OFF, E5 and E6 ON divides the phase-clock frequency by four, creating a 2.25 kHz servo-clock
frequency. This setting is seldom changed.

E29-E33: Phase Clock Frequency Control – Only one of the jumpers E29 – E33, which select the
phase-clock frequency, may be on in any configuration. The default setting of E31 ON, which selects a 9
kHz phase-clock frequency, is seldom changed.

E34-E38: Encoder Sample Clock – Only one of the jumpers E34 – E38, which select the encoder
sample clock frequency, may be on in any configuration. The frequency must be high enough to accept
the maximum true count rate (no more than one count in any clock period), but a lower frequency can
filter out longer noise spikes. The anti-noise digital delay filter can eliminate noise spikes up to one
sample-clock cycle wide.

E40-E43: Servo and Phase Clock Direction Control – Jumpers E40 – E43 determine the direction of
the phase and servo clocks. All of these jumpers must be ON for the card to use its internally generated
clock signals and to output these on the serial port connector. If any of these jumpers is OFF, the card
will expect to input these clock signals from the serial port connector, and its watchdog timer will trip
immediately if it does not receive these signals. The card number (0 – 15) for serial addressing of
multiple cards on a daisy-chain serial cable, set by these jumpers on older controllers, is determined by
the Turbo PMAC variable I0. See the Software Setup section of this manual for details.

E98: DAC/ADC Clock Frequency Control – Leave E98 in its default setting of 1-2, which creates a

2.45 MHz DCLK signal, unless connecting an Acc-28 A/D-converter board. In this case, move the
jumper to connect pins 2 and 3, which creates a 1.22 MHz DCLK signal.

Encoder Configuration Jumpers

Encoder Complementary Line Control – The selection of the type of encoder used, either single ended
or differential is made through the resistor packs configuration and not through a jumper configuration, as
on older controllers.

E22-E23: Control-Panel Handwheel Enable – Putting these jumpers ON ties the handwheel-encoder
inputs on the JPAN control-panel port to the Channel 2 encoder circuitry. If the handwheel inputs are
connected to Channel 2, no encoder should be connected to Channel 2 through the JMACH1 connector.

E72-E73: Control Panel Analog Input Enable – Putting these jumpers ON ties the output of the Option
10 voltage-to-frequency converter that can process the Wiper analog input on the JPAN control panel port
to the Channel 4 encoder circuitry. If the frequency signal is connected to Channel 4, no encoder should
be connected to Channel 4 through the JMACH1 connector.

E74-E75: Encoder Sample Clock Output – Putting these jumpers ON ties the encoder sample-clock
signal to the CHC4 and CHC4/ lines on the JMACH1 port. This permits the clock signal to be used to
synchronize external encoder-processing devices like the Acc-8D Option 8-interpolator board. With
these jumpers ON, no encoder input signal should be connected to these pins.

Hardware Setup 5

Turbo PMAC PCI Lite

Board Reset/Save Jumpers

E50: Flash-Save Enable/Disable Control – If E50 is ON (default), the active software configuration of
the PMAC can be stored to non-volatile flash memory with the SAVE command. If the jumper on E50 is
removed, this Save function is disabled, and the contents of the flash memory cannot be changed.

E51: Re-Initialization on Reset Control – If E51 is OFF (default), PMAC executes a normal reset,
loading active memory from the last saved configuration in non-volatile flash memory. If E51 is ON,
PMAC re-initializes on reset, loading active memory with the factory default values.

Communication Jumpers

PCI Bus Base Address Control – The selection of the base address of the card in the I/O space of the
host PC's expansion bus is assigned automatically by the operating system and it is not selected through a
jumper configuration.

E49: Serial Communications Parity Control – Jump pin 1 to 2 for NO serial parity. Remove jumper for
ODD serial parity.

E55-E65: Interrupt Source Control – These jumpers control which signals are tied to interrupt lines
IR5, IR6 and IR7 on PMAC’s programmable interrupt controller (PIC), as shown in the interrupt
diagram. Only one signal may be tied into each of these lines.

E110: Serial Port Configure – Jump pin 1 to 2 for use of the J4 connector as RS-232. Jump pin 2 to 3
for use of the J4 connector as RS-422.

E111: Clock Lines Output Enable – Jump pin 1 to 2 to enable the Phase, Servo and Init lines on the J4
connector. Jump pin 2 to 3 to disable the Phase, Servo and Init lines on the J4 connector. E111 on
positions 1 to 2 is necessary for daisy-chained PMACs sharing the clock lines for synchronization.

I/O Configuration Jumpers

Caution:

A wrong setting of these jumpers will damage the associated output IC.

E1-E2: Machine Output Supply Configure – With the default sinking output driver IC (ULN2803A or

equivalent) in U13 for the J5 JOPTO port outputs, these jumpers must connect pins 1 and 2 to supply the
IC correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these
jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.

E7: Machine Input Source/Sink Control – With this jumper connecting pins 1 and 2 (default) the
machine input lines on the J5 JOPTO port are pulled up to +5V or the externally provided supply voltage
for the port. This configuration is suitable for sinking drivers. If the jumper is changes to connect pins 2
and 3, these lines are pulled down to GND. This configuration is suitable for sourcing drivers.

E17A - E17D: Motors 1-4 Amplifier-Enable Polarity Control – Jumpers E17A through E17D control
the polarity of the amplifier enable signal for the corresponding motor 1 to 4. When the jumper is ON
(default), the amplifier-enable line for the corresponding motor is low true so the enable state is low­voltage output and sinking current, and the disable state is not conducting current. With the default
ULN2803A sinking driver used by the PMAC on U37, this is the fail-safe option, allowing the circuit to
fail in the disable state. With this jumper OFF, the amplifier-enable line is high true so the enable state is
not conducting current, and the disable state is low-voltage output and sinking current. Generally, this
setting is not recommended.

Caution:

A wrong setting of these jumpers will damage the associated output IC.

The U37 driver IC controls the AENA and EQU signals of motors 1 - 4. With the default sinking output
driver IC (ULN2803A or equivalent) in U37, these jumpers must connect pins 1 and 2 to supply the IC
correctly. If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these
jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly.

CPU Jumper Configuration

E10A-E10C: Flash Memory Bank Select Jumpers – The flash-memory IC in location U146 on the
Turbo PMAC PCI Lite board has the capacity for eight separate banks of firmware, only one of which can
be used at any given time. The eight combinations of settings for jumpers E10A, E10B, and E10C select
which bank of the flash memory is used. In the factory production process, firmware is loaded only into
Bank 0, which is selected by having all of these jumpers OFF.

E18-E20: Power-Up State Jumpers – Jumper E18 must be OFF, jumper E19 must be ON, and jumper
E20 must be ON, in order for the CPU to copy the firmware from flash memory into active RAM on
power-up/reset. This is necessary for normal operation of the card. (Other settings are for factory use
only.)

E21: Firmware Load Jumper – If jumper E21 is ON during power-up/reset, the board comes up in
bootstrap mode, which permits the loading of new firmware into the flash-memory IC on the board.
When the PMAC Executive program tries to establish communications with a board in this mode, it will
automatically detect that the board is in bootstrap mode and ask what file to download as the new
firmware.

Note:

Jumper E21 must be OFF during power-up/reset for the board to come up in
normal operational mode.

E119: Watchdog Timer Jumper - Jumper E119 must be OFF for the watchdog timer to operate. This is
an important safety feature, so it is vital that this jumper be OFF in normal operation. E1 should only be
put ON to debug problems with the watchdog timer circuit.

Resistor Pack Configuration: Flag and Digital Inputs Voltage Selection

The PMAC is provided with 6-pin sockets for SIP resistor packs for the input flag sets. Each PMAC is
shipped with no resistor packs installed. If the flag or digital inputs circuits are in the 12V to 15V range,
no resistor pack should be installed in these sockets. For flags or digital inputs at 5V levels, quad 1k SIP
resistor packs (1KSIP6C) should be installed in these sockets. The following table lists the voltage
selection resistor pack sockets for each input device:

Resistor Pack Configuration: Termination Resistors

The PMAC provides sockets for termination resistors on differential input pairs coming into the board.
As shipped, there are no resistor packs in these sockets. If these signals are brought long distances into
the PMAC board and ringing at signal transitions is a problem, SIP resistor packs may be mounted in
these sockets to reduce or eliminate the ringing.

All termination resistor packs are the types that have independent resistors (no common connection) with
each resistor using two adjacent pins. The following table shows which packs are used to terminate each
input device:

Resistor Pack Configuration: Differential or Single-Ended Encoder
Selection

The differential input signal pairs to the PMAC have user-configurable pull-up/pull-down resistor
networks to permit the acceptance of either single-ended or differential signals in one setting, or the
detection of lost differential signals in another setting.

The ‘+’ inputs of each differential pair each have a hard-wired 1 k pull-up resistor to +5V. This cannot
be changed.

The ‘-‘ inputs of each differential pair each have a hard-wired 2.2 k resistor to +5V. Each also has
another 2.2 k resistor as part of a socketed resistor pack that can be configured as a pull-up resistor to
+5V, or a pull-down resistor to GND.

If this socketed resistor is configured as a pull-down resistor (the default configuration), the combination
of pull-up and pull-down resistors on this line acts as a voltage divider, holding the line at +2.5V in the
absence of an external signal. This configuration is required for single-ended inputs using the ‘+’ lines
alone. It is desirable for unconnected inputs to prevent the pick-up of spurious noise. It is permissible for
differential line-driver inputs.

If this socketed resistor is configured as a pull-up resistor (by reversing the SIP pack in the socket), the
two parallel 2.2 k resistors act as a single 1.1 k pull-up resistor, holding the line at +5V in the absence

of an external signal. This configuration is required if encoder-loss detection is desired. It is required if
complementary open-collector drivers are used. It is permissible for differential line-driver inputs even
without encoder loss detection.

If Pin 1 of the resistor pack (marked by a dot on the pack) matches Pin 1 of the socket (marked by a wide
white square solder pin on the front side of the board), then the pack is configured as a bank of pull-down
resistors. If the pack is reversed in the socket, it is configured as a bank of pull-up resistors.

MACHINE CONNECTIONS

Typically, the user connections are made to a terminal block that is attached to the JMACH connector by
a flat cable (Acc-8D or 8P). The pinout numbers on the terminal block are the same as those on the
JMACH connector. The possible choices for breakout boards are:

Mounting

The PMAC can be mounted in one of two ways: in the PCI bus, or using standoffs.

PCI bus: To mount in the PCI bus, simply insert the P1 card-edge connector into PCI socket. If there

is a standard PC-style housing, a bracket at the end of the PMAC board can be used to screw into the
housing to hold the board down firmly.

Standoffs: At each of the four corners of the PMAC board, there are mounting holes that can be used

to mount the board on standoffs.

Power Supplies

Digital Power Supply

2A @ +5V (+/-5%) (10 W)
(Eight-channel configuration, with a typical load of encoders)

The host computer provides the 5V power supply in the case PMAC is installed in its internal bus.
With the board plugged into the bus, it will automatically pull +5V power from the bus and it cannot

be disconnected. In this case, there must be no external +5V supply, or the two supplies will fight
each other, possibly causing damage. This voltage could be measured between pins 1 and 3 of the
terminal block.

In a stand-alone configuration, when PMAC is not plugged in a computer bus, it will need an external

5V supply to power its digital circuits. The +5V line from the supply should be connected to pin 1 or
2 of the JMACH connector (usually through the terminal block), and the digital ground to pin 3 or 4.
Acc-1x provides different options for the 5V power supply.

Analog Power Supply

0.3A @ +12 to +15V (4.5W)

0.25A @ -12 to -15V (3.8W)
(Eight-channel configuration)

The analog output circuitry on PMAC is optically isolated from the digital computation circuitry, and so
requires a separate power supply. This is brought in on the JMACH connector. The positive supply (+12
to +15V) should be brought in on the A+15V line on pin 59. The negative supply (-12 to -15V) should be
brought in on the A-15V line on pin 60. The analog common should be brought in on the AGND line on
pin 58.

Typically, this supply can come from the servo amplifier. Many commercial amplifiers provide such a
supply. If this is not the case, an external supply may be used. Acc-2x provides different options for the ±
15V power supply. Even with an external supply, the AGND line should be tied to the amplifier common.
It is possible to get the power for the analog circuits from the bus, but doing so defeats optical isolation. In
this case, no new connections need to be made. However, be sure jumpers E85, E87, E88, E89, and E90
are set up for this circumstance. (The card is not shipped from the factory in this configuration.)

Overtravel Limits and Home Switches

When assigned for the dedicated uses, these signals provide important safety and accuracy functions.
+LIMn and -LIMn are direction-sensitive overtravel limits that must be actively held low (sourcing
current from the pins to ground) to permit motion in their direction. The direction sense of +LIMn and ­LIMn is as follows: +LIMn should be placed at the negative end of travel, and -LIMn should be placed at
the positive end of travel.

Types of Overtravel Limits

PMAC expects a closed-to-ground connection for the limits to not be considered on fault. This
arrangement provides a failsafe condition and therefore it cannot be reconfigured differently in PMAC.
Usually a passive normally closed switch is used. If a proximity switch is needed instead, use a 15V
normally closed-to-ground NPN sinking type sensor.

Jumper E89, E90 and E100 must be set appropriately for the type of sensor used.

Home Switches

While normally closed-to-ground switches are required for the overtravel limits inputs, the home switches
could be either normally closed or normally open types. The polarity is determined by the home sequence
setup, through the I-variables I902, I907, ... I977. However, for the following reasons, the same type of
switches used for overtravel limits are recommended:

Normally closed switches are proven to have greater electrical noise rejection than normally open types.
Using the same type of switches for every input flag simplifies maintenance stock and replacements.

Incremental Encoder Connection

Each JMACH connector provides two +5V outputs and two logic grounds for powering encoders and
other devices. The +5V outputs are on pins 1 and 2; the grounds are on pins 3 and 4. The encoder signal
pins are grouped by number: all those numbered 1 (CHA1, CHA1/, CHB1, CHC1, etc.) belong to
encoder #1. The encoder number does not have to match the motor number, but usually does.

If the PMAC is not plugged into a bus and drawing its +5V and GND from the bus, use these pins to
bring in +5V and GND from the power supply. Connect the A and B (quadrature) encoder channels to the
appropriate terminal block pins. For encoder 1, the CHA1 is pin 25, CHB1 is pin 21. If it is a single­ended signal, leave the complementary signal pins floating. Do not ground them. However, if single­ended encoders are used, make sure the resistor packs are in the default position (RP-60/62/66/68). For a
differential encoder, connect the complementary signal lines — CHA1/ is pin 27, and CHB1/ is pin 23.
The third channel (index pulse) is optional. For encoder 1, CHC1 is pin 17, and CHC1/ is pin 19.

DAC Output Signals

If PMAC is not performing the commutation for the motor, only one analog output channel is required to
command the motor. This output channel can be either single-ended or differential, depending on what
the amplifier is expecting. For a single-ended command using PMAC channel 1, connect DAC1 (pin 43)
to the command input on the amplifier. Connect the amplifier's command signal return line to PMAC's
AGND line (pin 58). In this setup, leave the DAC1/ pin floating. Do not ground it.

For a differential command using PMAC channel 1, connect DAC1 (pin 43) to the plus-command input
on the amplifier. Connect DAC1/ (pin 45) to the minus-command input on the amplifier. PMAC’s
AGND should still be connected to the amplifier common. If the amplifier is expecting separate sign and
magnitude signals, connect DAC1 (pin 43) to the magnitude input. Connect AENA1/DIR1 (pin 47) to the
sign (direction input). Amplifier signal returns should be connected to AGND (pin 58). This format
requires some parameter changes on PMAC. (See Ix25.) Jumper E17 controls the polarity of the direction
output. This may have to be changed during the polarity test. This magnitude-and-direction mode is
suited for driving servo amplifiers that expect this type of input and for driving voltage-to-frequency
(V/F) converters, such as PMAC’s Acc-8D Option 2 board, for running stepper motor drivers.

If using PMAC to commutate the motor, use two analog output channels for the motor. Each output may
be single-ended or differential, just as for the DC motor. The two channels must be numbered
consecutively, with the lower-numbered channel having an odd number (e.g., use DAC1 and DAC2 for a
motor, or DAC3 and DAC4, but not DAC2 and DAC3, or DAC2 and DAC4).

For our motor #1 example, connect DAC1 (pin 43) and DAC2 (pin 45) to the analog inputs of the amplifier.
If using the complements as well, connect DAC1/ (pin 45) and DAC2/ (pin 46) the minus-command inputs;
otherwise leave the complementary signal outputs floating. To limit the range of each signal to +/- 5V, use
parameter Ix69. Any analog output not used for dedicated servo purposes may be utilized as a general­purpose analog output. Usually this is done by defining an M-variable to the digital-to-analog-converter
register (suggested M-variable definitions M102, M202, etc.), then writing values to the M-variable. The
analog outputs are intended to drive high-impedance inputs with no significant current draw. The 220
output resistors will keep the current draw lower than 50 mA in all cases and prevent damage to the output
circuitry, but any current draw above 10 mA can result in noticeable signal distortion.

Amplifier Enable Signal (AENAx/DIRn)

Most amplifiers have an enable/disable input that permits complete shutdown of the amplifier regardless
of the voltage of the command signal. PMAC's AENA line is meant for this purpose. If not using a
direction and magnitude amplifier or voltage-to-frequency converter, use this pin to enable and disable
the amplifier (wired to the enable line). AENA1/DIR1 is pin 47. This signal is an open-collector output
with a 3.3 k pull-up resistor to +V, which is a voltage selected by jumper E100. The pull-up resistor
packs are RP43 for channels 1-4. For early tests, this amplifier signal should be under manual control.

This signal could be either sinking or sourcing as determined by chips U37 (see jumpers E100-E102).
For 24 Volts operation E100 must connect pins 2-3 and a separate power supply must be brought on pins
9-7 of the J9 JEQU connector. The polarity of the signal is controlled by jumpers E17A to E17D. The
default is low-true (conducting) enable. In addition, the amplifier enable signal could be manually
controlled setting Ix00=0 and using the suggested definition of the Mx14 variable.

Amplifier Fault Signal (FAULTn)

This input can take a signal from the amplifier so PMAC knows when the amplifier is having problems,
and can shut down action. The polarity is programmable with I-variable Ix25 (I125 for motor #1) and the
return signal is analog ground (AGND). FAULT1 is pin 49. With the default setup, this signal must
actively be pulled low for a fault condition. In this setup, if nothing is wired into this input, PMAC will
consider the motor not to be in a fault condition. The amplifier fault signal could be monitored using the
properly defined Mx23 variable.

Some amplifiers share the amplifier fault output with the amplifier enable\disable status output. In this
case a special PLC code must be written with the following sequence:

Disable the amplifier fault input (see Ix25)
Enable the motor (J/ command).
Wait for the amplifier fault input to be false (monitor Mx23).
Re-enable the amplifier fault input (see Ix25).

Turbo PMAC PCI Lite

General-Purpose Digital Inputs and Outputs (JOPTO Port)

PMAC’s J5 or JOPTO connector provides eight general-purpose digital inputs and eight general-purpose
digital outputs. Each input and each output has its own corresponding ground pin in the opposite row.
The 34-pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O
modules. Delta Tau’s Acc-21F is a six-foot cable for this purpose. Characteristics of the JOPTO port on
the PMAC:

16 I/O points; 100 mA per channel, up to 24V
Hardware selectable between sinking and sourcing in groups of eight. Default is all sinking (inputs

can be changed simply by moving a jumper. Sourcing outputs must be special-ordered or field­configured)

Eight inputs, eight outputs only; no changes. Parallel (fast) communications to PMAC CPU
Not opto-isolated; easily connected to Opto-22 (PB16) or similar modules through Acc-21F cable

Jumper E7 controls the configuration of the eight inputs. If it connects pins 1 and 2 (the default setting),
the inputs are biased to +5V for the OFF state, and they must be pulled low for the ON state. If E7
connects pins 2 and 3, the inputs are biased to ground for the OFF state, and must be pulled high for the
ON state. In either case, a high voltage is interpreted as a 0 by the PMAC software, and a low voltage is
interpreted as a 1.

Caution:

Do not connect these outputs directly to the supply voltage or damage to the
PMAC will result from excessive current draw.

PMAC is shipped standard with a ULN2803A sinking (open-collector) output IC for the eight outputs.
These outputs can sink up to 100 mA and have an internal 3.3 k pull-up resistor to go high (RP18). A
high-side voltage (+5 to +24V) can be provided to Pin 33 of the JOPTO connector, and allow this to pull
up the outputs by connecting pins 1 and 2 of Jumper E1. In addition, Jumper E2 must connect pins 1 and
2 for a ULN2803A sinking output.

It is possible for these outputs to be sourcing drivers by substituting a UDN2981A IC for the ULN2803A.
This U13 IC is socketed, and so may easily be replaced. For this driver, the internal resistor packs pull­down instead. With a UDN2981A driver IC, Jumper E1 must connect pins 2 and 3, and Jumper E2 must
connect pins 2 and 3.

Caution:

Having Jumpers E1 and E2 set wrong can damage the IC. The +V output on this
connector has a 2A fuse, F1, for excessive current protection.

The outputs can be configured individually to a different output voltage by removing the internal pull-up
resistor pack RP18 and connecting to each output a separate external pull-up resistor to the desired
voltage level.

Example: Standard configuration using the ULN2803A sinking (open-collector) output IC

Control-Panel Port I/O (JPAN Port)

The J2 (JPAN) connector is a 26-pin connector with dedicated control inputs, dedicated indicator outputs,
a quadrature encoder input, and an analog input. The control inputs are low-true with internal pull-up
resistors. They have predefined functions unless the control-panel-disable I-variable (I2) has been set to

1. If this is the case, they may be used as general-purpose inputs by assigning M-variable to their
corresponding memory-map locations (bits of Y address $78800).

Command Inputs

JOG-/, JOG+/, PREJ/ (return to pre-jog position), and HOME/ affect the motor selected by the FDPn/
lines (see below). The ones that affect a coordinate system are STRT/ (run), STEP/, STOP/ (abort), and
HOLD/ (feed hold) affect the coordinate system selected by the FDPn/ lines.

Selector Inputs

Caution:

It is not a good idea to change the selector inputs while holding one of the jog
inputs low. Releasing the jog input will then not stop the previously selected
motor. This can lead to a dangerous situation.

The four low-true BCD-coded input lines FDP0/ (LSBit), FDP1/, FDP2/, and FDP3/ (MSBit) form a low­true BCD-coded nibble that selects the active motor and coordinate system (simultaneously). These are
usually controlled from a single 4-bit motor/coordinate-system selector switch. The motor selected with
these input lines will respond to the motor-specific inputs. It will also have its position following
function turned on (Ix06 is set to 1 automatically). The motor just de-selected has its position following
function turned off (Ix06 is set to 0 automatically).

Alternate Use

If I2 has been set to 1, the discrete inputs can be used for parallel-data servo feedback or master position.
The Acc-39 Handwheel Encoder Interface board provides 8-bit parallel counter data from a quadrature
encoder to these inputs. Refer to the Acc-39 manual and Parallel Position Feedback Conversion section
in the Setting up a Motor section for more details.

Reset Input

Input INIT/ (reset) affects the entire card. It has the same effect as cycling power or a host $$$ command.
It is hard-wired, so it retains its function even if I2 is set to 1.

Handwheel Inputs

The handwheel inputs HWCA and HWCB can be connected to the second encoder counter on PMAC
with jumpers E22 and E23. If these jumpers are on, nothing else should be connected to the Encoder 2
inputs. The signal can be interpreted either as quadrature or as pulse (HWCA) and direction (HWCB),
depending on the value of I905. I905 also controls the direction sense of this input. Make sure that the
Encoder 2 jumper E26 is set for single ended signals, connecting pins 1 and 2.

Optional Voltage to Frequency Converter

The WIPER analog input (0 to +10V on PMAC referenced to digital ground) provides an input to a
voltage-to-frequency converter (V/F) with a gain of 25 kHz/Volt, providing a range of 0-250 kHz. The
output of the V/F can be connected to the Encoder 4 counter using jumpers E72 and E73. If these
jumpers are on, nothing else should be connected to the Encoder 4 inputs. Make sure that the Encoder 4
jumper E24 is set for single-ended signals, connecting pins 1 and 2. This feature requires the ordering of
Option 15.

Machine Connections 15

Turbo PMAC PCI Lite

Frequency Decode

When used in this fashion, Encoder 4 must be set up for pulse-and-direction decode by setting I915 to 0
or 4. Usually, a value of 4 is used because with CHB4 (direction) unconnected, a positive voltage causes
the counter to count up. The encoder conversion table can then take the difference in the counter each
servo cycle and scale it, providing a value proportional to frequency, and therefore to the input voltage.
Usually this is used for feedrate override (time base control), but the resulting value can be used for any
purpose.

Power Supply

For the V/F converter to work, PMAC must have +/-12V supply referenced to digital ground. If PMAC
is in a bus configuration, usually this comes through the bus connector from the bus power supply. In a
standalone configuration, this supply must still be brought through the bus connector (or the supply
terminal block), or it must be jumpered over from the analog side with E85, E87, and E88, defeating the
optical isolation on the board.

Thumbwheel Multiplexer Port (JTHW Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW (J3) connector has eight input lines
and eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on
the port, and Delta Tau provides accessory boards and software structures (special M-variable definitions)
to capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in
any combination.

The Acc-18 Thumbwheel Multiplexer board provides up to 16 BCD thumbwheel digits or 64 discrete

TTL inputs per board. The TWD and TWB forms of M-variables are used for this board.

The Acc-34x family Serial I/O Multiplexer boards provides 64 I/O point per board, optically isolated

from PMAC. The TWS form of M-variables is used for these boards.

The Acc-8D Option 7 Resolver-to-Digital Converter board provides up to four resolver channels

whose absolute positions can be read through the thumbwheel port. The TWR form of M-variables is
used for this board.

The Acc-8D Option 9 Yaskawa

these encoders. The absolute position is read serially through the multiplexer port on power up.

If none of these accessory boards is used, the inputs and outputs on this port may be used as discrete, non­multiplexed I/O. They map into PMAC’s processor space at Y address $78801. The suggested M­variable definitions for this use are M40 to M47 for the eight outputs, and M50 to M57 for the eight
inputs. The Acc-27 Optically Isolated I/O board buffers the I/O in this non-multiplexed form with each
point rated to 24V and 100 mA.

Absolute Encoder Interface board can connect to up to four of

Optional Analog Inputs (JANA Port)

The JANA port is present only if Option 12 is ordered for the PMAC. Option 12 provides eight 12-bit
analog inputs (ANAI00-ANAI07). Option 12A provides eight additional 12-bit analog inputs (ANA08­ANAI15) for a total of 16 inputs. The analog inputs can be used as unipolar inputs in the 0V to +5V
range, or bi-polar inputs in the -2.5V to +2.5V range.

The analog-to-digital converters on PMAC require +5V and -12V supplies. These supplies are not
isolated from digital +5V circuitry on PMAC. If the PMAC is plugged into the PCI bus, these supplies
are taken from the bus power supply. In a standalone application, these supplies must be brought in on
terminal block TB1. The -12V and matching +12V supply voltages are available on the J30 connector to
supply the analog circuitry providing the signals.

16 Machine Connections

Turbo PMAC PCI Lite

Only one pair of analog-to-digital converter registers is available to the PMAC processor at any given
time. The data appears to the processor at address Y:$78808. The data from the selected analog input 0
to 7 (ANAI00-ANAI07) appears in the low 12 bits; the data from the selected analog input 8 to 15
(ANAI08-ANAI15) appears in the high 12 bits (this data is only present if Option 12A has been ordered).
The input is selected and the conversion is started by writing to this same word address Y:$78808. A
value of 0 to 7 written into the low 12 bits selects the analog input channel of that number (ANAI00­ANAI07) to be converted in unipolar mode (0V to +5V). A value of 0 to 7 written into the high 12 bits
selects the analog input channel numbered eight greater (ANAI08-ANAI15) in unipolar mode. If the
value written into either the low 12 bits or the high 12 bits is eight higher (8 to 15), the same input
channel is selected, but the conversion is in bipolar mode (-2.5V to +2.5V).

Turbo PMAC variables I5060 to 5096 allow an automatic conversion of the analog inputs. Setting
variables I5061 to I5076 to 8 the data can be read from registers Y:$3400 to Y:$341F. See the Turbo

The compare-equals (EQU) outputs have a dedicated use of providing a signal edge when an encoder
position reaches a pre-loaded value. This is useful for scanning and measurement applications.
Instructions for use of these outputs are covered in detail in the PMAC’s User Manual.

Outputs can be configured sinking or sourcing by replacing the chip U37 and configuring the jumpers
E101-102. The voltage levels can be individually configured by removing resistor packs RP43 or RP56
and connecting an external pull-up resistor in each output to the desired voltage level.

Serial Port (JRS422 Port)

For serial communications, use a serial cable to connect the PC’s COM port to the PMAC’s J4 serial port
connector. Delta Tau provides the Acc-3D cable that connects the PMAC PCI to a DB-25 connector.
Standard DB-9-to-DB-25 or DB-25-to-DB-9 adapters may be needed for a particular setup. Jumper E110
selects between RS-232 or RS422 signals type for the J4 connector. If a cable needs to be made, use a
flat cable prepared with flat-cable type connectors as indicated in the following diagram:

SOFTWARE SETUP

Communications

Delta Tau provides communication tools that take advantage of the PCI bus Plug and Play feature of 32­bits Windows® based computers. With Pewin 32 Pro, a Turbo PMAC PCI Lite board plugged in a PCI
bus slot will be recognized by the operating system when the computer is boot up. The available PCI
address, dual-ported RAM address and interrupt lines are set automatically by the operating system and
can be checked (but not modified) in the resources page of the device manager.

Turbo PMAC I-Variables

Turbo PMAC has a large set of Initialization parameters (I-variables) that determine the personality of the
card for a specific application. Many of these are used to configure a motor properly. Once set up, these
variables may be stored in non-volatile flash memory (using the SAVE command) so the card is always
configured properly (PMAC loads the flash I-variable values into RAM on power-up).

The easiest way to program, setup and troubleshoot Turbo PMAC is by using the PMAC Executive
Program Pewin 32 Pro and its related add-on packages Turbo Setup and PMAC Plot. These software
packages are available from Delta Tau, ordered through the appropriate software accessory.

The programming features and configuration variables for the Turbo PMAC are fully described
in the Turbo PMAC User and Software manuals.

Operational Frequency and Baud Rate Setup

Variable I52 determines the actual operating frequency of the Turbo CPU. The operational frequency is
set to 10MHz * (I52 + 1). I52 should be set to 7 to operate an Option 5Cx board at its maximum rated
frequency of 80 MHz; it should be set to 9 to operate an Option 5Dx board at its maximum rated
frequency of 100 MHz; it should be set to 15 to operate an Option 5Ex board at is maximum rated
frequency of 160 MHz.

I52 is used only at power-up/reset. To change the operational frequency, set a new value of I52, issue a
SAVE command to store this value in non-volatile flash memory, then issue a $$$ command to reset the
controller. I54 controls the baud rate for communications on the main serial port. Turbo PMAC uses I54
only at power-up/reset to set up the frequency of the clocking circuit for the serial port. To change the
baud rate, it is necessary to change the value of I54, store this value to non-volatile flash memory with the
SAVE command, and reset the card. At this time, Turbo PMAC will establish the new baud rate.

The possible settings of I54 and the baud rates they define are:

20 Software Setup

Turbo PMAC PCI Lite

If the host computer baud rate does not match the Turbo PMAC’s baud rate, either the Turbo PMAC’s
baud rate must be changed through the bus communications port, or the Turbo PMAC must be re­initialized by resetting or powering up with the E51 jumper ON. This forces the Turbo PMAC to the
default baud rate of 38,400.

Note:

To use the baud rate of 115,200, the CPU must be operating at an exact multiple of
30MHz (i.e., 30, 60, 90, 120, or 150MHz).

Turbo PMAC PCI Lite

Connectors and Indicators

J1 – Display Port (JDISP Port)

The JDISP connector allows connection of the Acc-12 or Acc-12A liquid crystal displays, or of the Acc­12C vacuum fluorescent display. Both text and variable values may be shown on these displays by using
the DISPLAY command, executing in either motion or PLC programs.

J2 – Control-Panel Port (JPAN Port)

The JPAN connector is a 26-pin connector with dedicated control inputs, dedicated indicator outputs, a
quadrature encoder input, and an analog input (requires PMAC Option 15). The control inputs are low
true with internal pull-up resistors. They have predefined functions unless the control-panel-disable I­variable (I2) has been set to 1. If this is the case, they may be used as general-purpose inputs by assigning
M-variable to their corresponding memory-map locations (bits of Y address $78800).

J3 – Thumbwheel Multiplexer Port (JTHW Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW connector has eight input lines and
eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on the
port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to
capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in
any combination.

J4 – Main Serial Port (JRS232/422 Port)

For serial communications, use a serial cable to connect the PC’s COM port to the PMAC’s serial port

connector. Delta Tau provides the Acc-3D cable for this purpose, which connects PMAC to a DB-25
connector. Standard DB-9-to-DB-25 or DB-25-to-DB-9 adapters may be needed for a particular setup.

J5 – General-Purpose Digital Inputs and Outputs (JOPTO Port)

PMAC’s JOPTO connector provides eight general-purpose digital inputs and eight general-purpose
digital outputs. Each input and each output has its own corresponding ground pin in the opposite row.
The 34-pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O
modules. Delta Tau’s Acc-21F is a six-foot cable for this purpose.

J6 – Auxiliary I/O Port (JXIO Port)

This port is only used when connecting to optional PMAC accessory boards.

J8 – Machine Connectors (JMACH1 Port)

The primary machine interface connector is JMACH1, labeled J8 on the PMAC. It contains the pins for
four channels of machine I/O: analog outputs, incremental encoder inputs, and associated input and output
flags, plus power-supply connections.

J9 – Compare Equal Outputs Port (JEQU Port)

The compare-equals (EQU) outputs have a dedicated use of providing a signal edge when an encoder
position reaches a pre-loaded value. This is very useful for scanning and measurement applications.
Instructions for use of these outputs are covered in detail in the PMAC’s User Manual.

J17 – Auxiliary Serial Port (JRS232 Port)

This connector allows the Turbo PMAC to communicate through its optional auxiliary RS-232 serial port.

J30 – Optional Analog to Digital Inputs (JANA Port)

This optional port is used to bring in the analog signals for the optional on-board analog to digital
converter set. This feature provides up to 16 analog inputs in the range of 0 to 5V unipolar or ±2.5V
bipolar.

J31 – Optional Universal Serial Bus Port (JUSB Port)

26 Hardware Reference Summary

Turbo PMAC PCI Lite

This optional port allows communicating with PMAC through a standard USB connection.

J32 – Expansion Port (JEXP Port)

This port is used to connect to PMAC accessory board that require data and address bus access.

JS1 – External A/D Port (JS1 Port)

This port is only used when connecting to Acc-28A/B analog-to-digital converter boards.

TB1 – Power Supply Terminal Block (JPWR Connector)

This terminal block may be used as an alternative power supply connector if PMAC is not installed in a
PCI-bus.

LED Indicators

D20 and D20A: When these green LEDs are lit, they indicate that power is applied to the +5V input.
D21 and D21A: When these red LEDs are lit, they indicate that the watchdog timer has tripped and shut

down the PMAC.
D15: The PMAC has an interlock circuit that drops out the ±15V supplies to the analog outputs through a

fail-safe relay if any supply on PMAC is lost. In this case, the green LED D15 will be off.

Fuse

The 5V output through the J5 JOPTO connector is protected by F1, which is a two-Amp fuse of the
following type:

E3 - E6: Servo Clock Frequency Control

The servo clock (which determines how often the servo loop is closed) is derived from the phase clock (see
E98, E29 - E33) through a divide-by-N counter. Jumpers E3 through E6 control this dividing function.

Note:

The setting of I-variable I10 should be adjusted to match the servo interrupt cycle
time set by E98, E3 – E6, E29 – E33, and the crystal clock frequency. I10 holds
the length of a servo interrupt cycle, scaled so that 8,388,608 equals one
millisecond. Since I10 has a maximum value of 8,388,607, the servo interrupt
cycle time should always be less than a millisecond (unless the basic unit of time
on PMAC is something other than a millisecond). To have a servo sample time
greater than one millisecond, the sampling may be slowed in software with
variable Ix60.

Frequency can be checked on J4 pins 21 and 22. It can also be checked from software by typing RX :0 in
the PMAC terminal at 10-second intervals and dividing the difference of successive responses by 10000.
The resulting number is the approximate Servo Clock frequency kHz.

Note:

If E40 – E43 are not all ON, the phase clock is received from an external source
through the J4 serial-port connector, and the settings of E3 – E6 are not relevant.

The JTHW multiplexer port provides eight inputs and eight outputs at TTL levels. While these I/O can be used in
un-multiplexed form for 16 discrete I/O points, most users will utilize PMAC software and accessories to use this
port in multiplexed form to greatly multiply the number of I/O that can be accessed on this port. In multiplexed
form, some of the SELn outputs are used to select which of the multiplexed I/O are to be accessed.

The JRS422 connector provides the PMAC with the ability to communicate both in RS422 and RS232. In addition,
this connector is used to daisy chain interconnect multiple PMACs for synchronized operation.

Jumper E110 selects between RS-232 or RS-422 signal types.
Jumper E111 enables or disables the use of the Phase, Servo and Init lines
* Note: Required for communications to an RS-422 host port
** Note: Required for communications to an RS-422 or RS-232 host port
*** Note: Output on card @0; input on other cards. These pins are for synchronizing multiple PMACs together by
sharing their Phase and Servo clocks. The PMAC designated as card 0 (@0) by its jumpers E40-E43, outputs its
clock signals. Other PMACs designated as cards 1-15 (@1-@F) by their jumpers E40-E43, take these signals as
inputs. If synchronization is desired, these lines should be connected even if serial communications is not used.

The J8 connector is used to connect PMAC to the first four channels (Channels 1, 2, 3, and 4) of servo amps, flags,
and encoders.
Note 1: In standalone applications, these lines can be used as +5V power supply inputs to power PMAC's digital
circuitry. However, if a terminal block is available on a version of PMAC, it is preferable to bring the +5V power in
through the terminal block.
Note 2: Referenced to digital common (GND). Maximum of + 12V permitted between this signal and its
complement.
Note 3: Leave this input floating if not used (i.e. digital single-ended encoders). In this case, jumper (E18 - 21, E24

- 27) for channel should hold input at 2.5V.

Note 4: + 10V, 10mA max, referenced to analog common (AGND).
Note 5: Leave floating if not used. Do not tie to AGND. In this case AGND is the return line.
Note 6: Functional polarity controlled by jumper(s) E17. Choice between AENA and DIR use controlled by Ix02

and Ix25.
Note 7: Functional polarity controlled by variable Ix25. Must be conducting to 0V (usually AGND) to produce a '0'
in PMAC software. Automatic fault function can be disabled with Ix25.
Note 8: Pins marked -LIMn should be connected to switches at the positive end of travel. Pins marked +LIMn
should be connected to switches at the negative end of travel.
Note 9: Must be conducting to 0V (usually AGND) for PMAC to consider itself not into this limit. Automatic limit
function can be disabled with Ix25.
Note 10: Functional polarity for homing or other trigger use of HMFLn controlled by Encoder/Flag Variable 2
(I902, I907, etc.) HMFLn selected for trigger by Encoder/Flag Variable 3 (I903, I908, etc.). Must be conducting to
0V (usually AGND) to produce a '0' in PMAC software.

This connector provides the position-compare outputs and the amplifier enable outputs for the four servo interface
channels. The board is shipped by default with a ULN2803A or equivalent open-collector driver IC on U37. It may
be replaced with UDN2891A or equivalent open-emitter driver (E101-E102 must be changed!), or a 74ACT563 or
equivalent 5V CMOS driver.

This terminal block may be used as an alternative power supply connector if PMAC is not installed in a PCI-bus.
The +5V powers the digital electronics. The +12V and -12V (if jumpers E85, E87, and E88 are installed), power the
analog output stage (this defeats the optical isolation on PMAC).

To keep the optical isolation between the digital and analog circuits on PMAC, provide analog power (+/-12V to +/­15V and AGND) through the JMACH connector, instead of the bus connector or this terminal block.
