Caution
Some code examples require the user to input specific information
pertaining to their system hardware. When user information is
required, a commentary ending with –User Input is inserted.
Caution
All PLC examples are stated in PLC number 1. It is the user’s
responsibility to arrange their application PLCs’ properly and handle
power-on sequencing for various tasks.
Caution
Often times, downloadable example codes use suggested M-variables,
it is the user’s responsibility to make sure they are downloaded, or
perform necessary changes to use the intended registers.
Downloadable Turbo PMAC Script
This manual contains downloadable code samples in Turbo PMAC script. These examples can be copied
and pasted into the editor area in the Pewin32pro2. Care must be taken when using pre-configured Turbo
PMAC code, some information may need to be updated to match hardware and system specific

WARNING
Boards with revisions 103 and below have the following
requirement:
Mininumum 10 msec rise time
6A @ +5V (±5%) (30 W)
The Clipper Board and other stackable accessories each require a
1A @ 5VDC power supply for normal operation; however, the
Clipper board has an in-rush current requirement that can reach
3A, so a 6A @ 5VDC power supply is recommended.
Environmental Specifications
Electrical Specifications
Digital Power Supply
The +5V and ground reference lines from the power supply should be connected to TB1 terminal block of
the Turbo PMAC Clipper board using 18 AWG stranded wire. The power requirement (± 5%) is:
+5 V (20W) @ 4 A (Eight-channel configuration with a typical load of encoders)
DAC Outputs Power Supply
The ±12V lines from the supply, including the ground reference, can be brought in either from the TB1
terminal block or from the JMACH1 connector.
+12 to +15 V (4.5W) @ 0.30 A (Eight-channel configuration with a typical load of encoders)
-12 to -15 V (3.8W) @ 0.25 A (Eight-channel configuration with a typical load of encoders)
Flags Power Supply
Each channel of PMAC has five dedicated digital inputs on the machine connector: PLIMn, MLIMn
(overtravel limits), HOMEn (home flag), FAULTn (amplifier fault), and USERn. A power supply from 5
to 24V must be used to power the circuits related to these inputs. This power supply can be the same
used to Turbo PMAC Clipper and can be connected from the TB1 terminal block or the J3 (JMACH1)
connector.

RECEIVING AND UNPACKING
Delta Tau products are thoroughly tested at the factory and carefully packaged for shipment. When the
Turbo PMAC Clipper is received, there are several things to be done immediately:
Observe the condition of the shipping container and report any damage immediately to the
commercial carrier that delivered the board.
Remove the Turbo PMAC Clipper from the shipping container and remove all packing materials.
Check all shipping material for connector kits, documentation, or other small pieces of
equipment. Be aware that some connector kits and other equipment pieces may be quite small
and can be accidentally discarded if care is not used when unpacking the equipment. The
container and packing materials may be retained for future shipment.
Verify that the part number of the board received is the same as the part number listed on the
purchase order.
Inspect for external physical damage that may have been sustained during shipment and report
any damage immediately to the commercial carrier that delivered the board.
Electronic components in this product are design-hardened to reduce static sensitivity. However,
use proper procedures when handling the equipment.
If the Turbo PMAC Clipper is to be stored for several weeks before use, be sure that it is stored in
a location that conforms to published storage humidity and temperature specifications.
Use of Equipment
The following restrictions will ensure the proper use of the Turbo PMAC Clipper:
The components built into electrical equipment or machines can be used only as integral
components of such equipment.
The Turbo PMAC Clipper must not be operated on power supply networks without a ground or
with an asymmetrical ground.
If the Turbo PMAC Clipper is used in residential areas, or in business or commercial premises,
implement additional filtering measures.
The Turbo PMAC Clipper may be operated only in a closed switchgear cabinet, taking into
account the ambient conditions defined in the environmental specifications.
Delta Tau guarantees the conformance of the Turbo PMAC Clippers with the standards for industrial
areas stated in this manual, only if Delta Tau components (cables, controllers, etc.) are used.
Connections and Software Setup 14
Turbo PMAC Clipper
Caution
Unit must be installed in an enclosure that meets the environmental IP
rating of the end product (ventilation or cooling may be necessary to
prevent enclosure ambient from exceeding 45° C [113° F]).
MOUNTING
The location of the Turbo PMAC Clipper is important. Installation should be in an area that is protected
from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and other contaminants.
Exposure to these can reduce the operating life and degrade performance of the board.
Several other factors should be carefully evaluated when selecting a location for installation:
For effective cooling and maintenance, the Turbo PMAC Clipper should be mounted on a
smooth, non- flammable vertical or horizontal surface.
At least 100 mm (0.4 inches) top and bottom clearance must be provided for air flow.
Temperature, humidity and Vibration specifications should also be taken in account.
The Turbo PMAC Clipper can be mounted as a stand-alone controller using standoffs. At each of the
four corners of the board and at the center edges, there are mounting holes that can be used for this.
The order of the Acc-1P or other stacked accessories with respect to the Clipper Board does not matter.
If the Turbo PMAC Clipper is mounted to a back panel, the back panel should be unpainted and
electrically conductive to allow for reduced electrical noise interference. The back panel should be
machined to accept the standoffs pattern of the board.
The board can be mounted to the back panel using four standoffs and internal-tooth lock washers. It is
important that the teeth break through any anodization on the board’s mounting gears to provide a good
electrically conductive path in as many places as possible. Mount the board on the back panel so there is
airflow at both the top and bottom areas of the board (at least 0.4 inches).

J2: Serial Port
This connector allows communicating with Turbo PMAC Clipper from a host computer through a RS232 port. Delta Tau provides the Accessory 3L cable that connects the PMAC to a DB-9 connector. This
port can be used as a primary communication mean or employed as a secondary port that allows
simultaneous communication.
The baud rate for the RS-232 serial port is set by variable I54. At power-up reset, The Turbo PMAC
Clipper sets the active baud based on the setting of I54 and the CPU speed I52. Note that the baud rate
frequency is divided down from the CPU’s operational frequency. The factory default baud rate is 38400.
This baud rate will be selected automatically on re-initialization of the Clipper, either in hardware power
cycle or in software using the $$$*** command.
To change the baud rate setting on the Turbo PMAC Clipper, set I54 to the corresponding value of
desired frequency. Restart the software (Pewin32Pro2), and adjust to the correct baud rate in the
communication setup window. Then issue a SAVE and a reset ($$$), or recycle power on the Clipper. For
odd baud rate settings, refer to the Turbo Software Reference Manual.
The primary machine interface connector is JMACH1, labeled J3 on the Turbo PMAC Clipper. It
contains the pins for four channels of machine I/O: analog outputs, incremental encoder inputs, amplifier
fault and enable signals and power-supply connections.

Note
Note 1: These lines can be used as +5V power supply inputs to power
PMAC’s digital circuitry.
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).
Note 4: ±10V, 10 mA max, referenced to common ground (GND).
Note 5: Leave floating if not used. Do not tie to GND.
Note 6: Functional polarity controlled by variable Ixx24. Must be
conducting to 0V (usually GND) to produce a 0 in PMAC software.
Automatic fault function can be disabled with Ixx24.
Note 7: Can be used to provide input power when the TB1 connector is
The standard encoder inputs on the Turbo PMAC Clipper are designed for differential quadrature type
signals.
Quadrature encoders provide two digital signals to determine the position of the motor. Each nominally
with 50% duty cycle, and nominally 1/4 cycle apart. This format provides four distinct states per cycle of
the signal, or per line of the encoder. The phase difference of the two signals permits the decoding
electronics to discern the direction of travel, which would not be possible with a single signal.
Typically, these signals are 5V TTL/CMOS level whether they are single-ended or differential.
Differential signals can enhance noise immunity by providing common mode noise rejection. Modern
design standards virtually mandate their use in industrial systems.

single ended encoders may require tying the negative pins to
ground in series with a 1-2 KOhm resistors.
Some motor manufacturers bundle the hall sensors with the
motor-lead cable. The hall sensors must be brought into J7
connector.
Differential Quadrature Encoder Wiring for Channel #1
Setting up Quadrature Encoders
Digital Quadrature Encoders use the 1/T incremental entry in the encoder conversion table. Position and
velocity pointers should, by default, be valid and in most cases no software setup is required, activating
(Ixx00=1) the corresponding channel is sufficient to see encoder counts in the position window when the
motor/encoder shaft is moved by hand.
For sinusoidal position feedback, the Acc-51S, sine wave input interpolator, stacks on top of the Turbo
PMAC Clipper or on top of the Acc-1P 5-8 axis board. Channels 1 – 4 of the ACC-51S correspond to
PMAC channels 1 – 4 if the ACC-51S is connected to the main Turbo PMAC Clipper; channels 1 – 4 of
the ACC-51S correspond to PMAC channels 5 – 8 if the ACC-51S is connected to the ACC-1P board.
Connections and Software Setup 22
Turbo PMAC Clipper Hardware Reference Manual
Note
ACC-51S channels 1 – 4 become PMAC channels 1 – 4 if ACC-
51S jumper E1 connects pins 2 and 3.
ACC-51S channels 1 – 4 become PMAC channels 5 – 8 if ACC
51S jumper E1 connects pins 1 and 2.

cycles. Motor counts can be monitored in the motor position window upon moving the motor by hand.
Examples:
A 1024 Sine/Cosine periods per revolution of a rotary encoder produces 1024 x 128 = 131,072 cts/rev.
A 20 μm linear encoder resolution produces 128/0.02 = 6400 cts/mm.

The analog outputs are intended to drive high-impedance inputs with
no significant current draw (10mA max). 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 Fault Signal (FAULT-)
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 Ixx24 (I124 for motor 1) and the
return signal is ground (GND). FAULT1- is pin 35. 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 optional analog-to-digital converter inputs are ordered either through Option-12 on the Turbo PMAC
Clipper or Option-2 on the axis expansion board. Each option provides two 12-bit analog inputs with a
±10Vdc range, and one 12-bit filtered PWM DAC output.
Example for Analog Input 1
The M-variables associated with these inputs provided a range of values between +2048 and –2048 for
the respective ±10Vdc input range. The following is the software procedure to setup and read these ports.

software.
Note 11: Even if it is not used but connected, long cabling may
pull this line low and cause PMAC to unintentionally reset.
When assigned for the dedicated uses, these signals provide important safety and accuracy functions.
PLIMn and MLIMn are direction-sensitive over-travel limits that must conduct current to permit motion
in that direction. If no over-travel switches will be connected to a particular motor, this feature must be
disabled in the software setup through the PMAC Ixx24 variable.
Wiring the Limits and Flags
PMAC expects a closed-to-ground connection for the limits to not be considered on fault. This
arrangement provides a failsafe condition. Usually, a passive normally close switch is used. If a
proximity switch is needed instead, use a 5 to 24V normally closed to ground NPN sinking type sensor.

J7: Machine Connector (JMACH3 Port)
This machine interface connector is labeled JMACH3 or J7 on the Turbo PMAC Clipper. It contains the
pins for four channels of U, V, and W flags normally used for hall device commutation.
Thumbwheel Multiplexer Port on the JTHW connector has 8 inputs and 8 outputs at TTL levels. 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. In this form, some of the SELn outputs are used to select which of the multiplexed I/O are to be
accessed. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination.

J10: Handwheel and Pulse/Dir Connector (JHW/PD Port)
JHW/PD port provides two Quadrature encoder inputs and PFM or PWM output pairs from the
DSPGate2 supplemental channels 1* and 2*.
The electrical ground plane of the host PC connected through USB
must be at the same level as the Turbo PMAC Clipper. Ground loops
may result in ESD shocks causing the damage of the communication
processor on the Turbo PMAC Clipper.
Note
Use a shielded USB (category 6 or 7) cable. In noise sensitive
environment, install ferrite cores at both Clipper and PC side.
J12: Ethernet Communications Port
This connector is used to establish communication over Ethernet between the PC and the Turbo PMAC
Clipper. A crossover cable is required if you are going directly to the Clipper from the PC Ethernet card,
and not through a hub.
Delta Tau strongly recommends the use of RJ45 CAT5e or better shielded cable. Newer network cards
have the Auto-MDIX feature that eliminates the need for crossover cabling by performing an internal
crossover when a straight cable is detected during the auto-negotiation process. For older network cards,
one end of the link must perform media dependent interface (MDI) crossover (MDIX), so that the
transmitter on one end of the data link is connected to the receiver on the other end of the data link (a
crossover/patch cable is typically used). If an RJ45 hub is used, then a regular straight cable must be
implemented. Maximum length for Ethernet cable should not exceed 100m (330ft).
J13: USB Communications Port
This connector is used to establish USB (A-B type cable) communication between the host PC and the
Turbo PMAC Clipper. This type of USB cable can be purchased at any local electronics or computer
store. It may be ordered from Delta Tau as well.
JP11: OPT-11 Shunt
Not present if OPT-11 is installed. For internal use only.

DRIVE - MOTOR SETUP
The Turbo PMAC Clipper supports three types of outputs:
Analog ±10V 12-bit Filtered PWM
Analog ±10V 18-bit True DAC with Acc-8ES
Pulse Frequency Modulation (PFM)
The following chart summarizes the steps to implement for setting up a motor properly with the Turbo
PMAC Clipper:
Drive – Motor Setup 44
Turbo PMAC Clipper Hardware Reference Manual
Note
Some amplifiers operate in the ±5V range; this can be regulated using
the motor command output limit, parameter Ixx69.
Note
Filtered PWM Output Configuration sets the Max PWM
frequency very high (29KHz). This setting can be problematic
with Direct PWM commutation on the same servo IC.
The ACC-28A and ACC-28B cannot be used on the same servo
IC since the PWM frequency settings are out of range for these
products.
PWM Frequency
Resolution
Ripple
Filtered PWM Output (Analog ±10V)
In this mode, the ±10V analog output is obtained by passing the digital PWM signal through a 10 KHz
low pass filter. This technique, although not as performing as a true digital to analog converter, is more
than adequate for most servo applications.
The duty cycle of the PWM signal controls the magnitude of the voltage output. This is handled internally
by the PMAC, the user needs not to change any settings.
However, the frequency of the PWM signal determines the output resolution and ripple magnitude
(disturbance). The trade-off is as follows:
The higher the PWM frequency, the lower is the resolution with a low-ripple signal output.
The lower the PWM frequency, the higher is the resolution with a high-ripple signal output.
Both the resolution and the frequency of the Filtered PWM outputs are configured in software on the
Turbo PMAC Clipper through the variable I7000. This variable also effects the phase and servo
interrupts. Therefore as we change I7000 we will also have to change I7001 (phase clock divider), I7002
(servo clock divider), and I10 (servo interrupt time). These four variables are all related and must be
understood before adjusting parameters. The detailed information for these parameters can be found in
the Turbo Software Reference Manual.
Drive – Motor Setup 45
Turbo PMAC Clipper Hardware Reference Manual
Clock Settings, Output Mode, Command Limit
Most commonly used and suggested clock settings in this mode allowing a good compromise are a 29.4
KHz PWM Frequency, 9.8 KHz Phase, and 2.45 KHZ Servo.
The following diagram showcases important bit settings pertaining to flags, and amplifier information:
Example:
Setting Ixx24 for a low true amplifier and disabling the over-travel limit switches yields $20001.
I124,4,100 = $20001
I2T Protection: Ixx57, Ixx58
I2T is a software thermal model (PMAC internal calculation) used to protect motor and drive from
exceeding current specifications. For a safe setup, the lower limit of continuous and peak current
specifications between the motor and drive should be selected.
Example:
A Turbo PMAC Clipper driving a torque-mode amplifier that has a gain of 3 amperes/volt and a
continuous current rating of 10 amperes, with a motor rated to 12 amperes continuous.
Using the amplifier’s continuous current rating of 10 Amps:
#define ContCurrent 10 ; Continuous Current Limit [Amps] –User Input
#define MaxADC 30 ; full range ADC reading, Amplifier Spec. –User Input
#define I2TOnTime 2 ; Time allowed at peak Current, Amp/motor spec [sec] –User Input
#define ServoClk 2.45 ; Servo Clock, pre-defined in suggested clocks [Khz]
The open-loop test is critical to verify the direction sense of the encoder counting versus the command
output. A positive command should create a positive velocity and a position counting in the positive
direction; a negative command should create a negative velocity and a position counting in the negative
direction. The Open Loop test utility in the PMACTuningPro2 Software can be used to execute and open
loop test. It can also be carried manually from the terminal window while gathering position, velocity data
or simply monitoring the motor velocity in the position window.
Drive – Motor Setup 47
Turbo PMAC Clipper Hardware Reference Manual
The open-loop test is usually
performed on an unloaded motor.
The open loop command output is
adjustable, start off with a
conservative 1 to 2 percent
command output (i.e. #nO2) value
and increment gradually until you
see a satisfactory result.
If the failure persists (inverted saw
tooth, as shown in the plot), or you
observe oscillations in the response
instead of a saw tooth, then most
likely the direction sense of the
encoder is opposite to the command
output.
Unsatisfactory Open Loop Test Result
Satisfactory Open-Loop Test Result
General recommendation for troubleshooting an unsuccessful open loop test
An inverted saw tooth response, most times, indicates that the direction sense of the encoder is opposite to
that of the command output.
Quadrature | Sinusoidal:
Change I7mn0 to 3 from 7 (default) or vice-versa.
Absolute Serial Encoders (EnDat, SSI, BiSS, Yaskawa, Panasonic, Tamagawa, Mitutoyo):
The Turbo PMAC Clipper has no control on the direction sense of the serial data stream
(packets). There are no software parameters that allow changing the direction sense of absolute
serial encoders. Normally, it is set by jumpers or software at the encoder side.
Some amplifiers allow swapping the DAC+ and DAC- signal to invert the direction travel of the
motor. Otherwise, two of the motor leads have to be swapped.
Drive – Motor Setup 48
Turbo PMAC Clipper Hardware Reference Manual
Note
At this point of the setup, the motor(s) is ready to accept Jog
commands.
If the motor/axis direction does not comply now with the machine design then negative jog

motor can then assigned to a negative axis definition.
Position-Loop PID Gains: Ixx30…Ixx39
The position-loop tuning is done as in any Turbo PMAC PID-Loop setup. The PMACTuningPro2

I2T Protection: Ixx57, Ixx58
I2T is a software thermal model (PMAC internal calculation) used to protect motor and drive from
exceeding current specifications. For a safe setup, the lower limit of continuous and peak current
specifications between the motor and drive should be selected.
Example:
A Turbo PMAC Clipper driving a torque-mode amplifier that has a gain of 3 amperes/volt and a
continuous current rating of 10 amperes, with a motor rated to 12 amperes continuous.
Using the amplifier’s continuous current rating of 10 Amps:

The open-loop test is usually performed
on an unloaded motor. The open loop
command output is adjustable, start off
with a conservative 1 to 2 percent
command output (i.e. #nO2) value and
increment gradually until you see a
satisfactory result.
If the failure persists (inverted saw tooth,
as shown in the plot), or you observe
oscillations in the response instead of a
saw tooth, then most likely the direction
sense of the encoder is opposite to the
command output.
Unsatisfactory Open Loop Test Result
Open Loop Test: Encoder/Decode
The open-loop test is critical to verify the direction sense of the encoder counting versus the command
output. A positive command should create a positive velocity and a position counting in the positive
direction; a negative command should create a negative velocity and a position counting in the negative
direction. The Open Loop test utility in the PMACTuningPro2 Software can be used to execute and open
loop test. It can also be carried manually from the terminal window while gathering position, velocity data
or simply monitoring the motor velocity in the position window.
Satisfactory Open-Loop Test Result
General recommendation for troubleshooting an unsuccessful open loop test
An inverted saw tooth response, most times, indicates that the direction sense of the encoder is opposite to
that of the command output.

Quadrature | Sinusoidal:
Change I7mn0 to 3 from 7 (default) or vice-versa.
Absolute Serial Encoders (EnDat, SSI, BiSS, Yaskawa, Panasonic, Tamagawa, Mitutoyo):
The Turbo PMAC Clipper has no control on the direction sense of the serial data stream
(packets). There are no software parameters that allow changing the direction sense of absolute
serial encoders. Normally, it is set by jumpers or software at the encoder side.
Some amplifiers allow swapping the DAC+ and DAC- signal to invert the direction travel of the
motor. Otherwise, two of the motor leads have to be swapped.
If the motor/axis direction does not comply now with the machine design then negative jog
commands can be issued for positive motion, and vice versa. Similarly, for motion programs, the
motor can then assigned to a negative axis definition.

Pulse and Direction Output (PFM)
The Pulse and direction (Pulse Frequency Modulation) output pins are located on the J4 (JMACH2)
connector. The stepper drive specifications dictate the choice of the maximum PFM clock frequency, and
pulse width.
DT Calculator Forum Link
Step 1: Choose Max PFM clock by changing the PFM clock divider. Click on calculate to see results.
Step 2: Choose PFM Pulse width by changing I7m04. Click on calculate to see results.
The output frequency control Ixx69 specifies the maximum command output value which corresponds to
the maximum PFM Frequency.
PFM Clock Settings Example
Take a desired PFM clock frequency of 0-20 KHz, and a pulse width of ~20 μsec:
// Channels 1-4 PFM Clock Settings
I7003 = 2290 ; Servo IC 0 PFM Clock divider equal to 6
I7004 = 13 ; Servo IC 0 PFM Pulse Width Control equal to 13

// Channels 5-8 PFM Clock Settings
I7103 = 2290 ; Servo IC 1 PFM Clock divider equal to 6 (First Acc-1P)
I7104 = 13 ; Servo IC 1 PFM Pulse Width Control equal to 13 (First Acc-1P)
I569,4,100 = 2427 ; Output Command Limit (First Acc-1P)
// Channels 9-12 PFM Clock Settings

Writing directly to the suggested M-variable(s) values proportional to Ixx69 produces corresponding
frequencies:
Issuing Open-Loop Commands
Activating the motor channel should be sufficient at this point to allow open loop commands. Note that an
open loop command of zero magnitude (#nO0) will result in a zero frequency output, and an open loop
command of 100 (#nO100) will result in the maximum calculated frequency output.

Going back to the setup example, these are some open loop commands resulting frequencies:
Issuing Closed-Loop Commands
Issuing closed-loop commands requires activating the channel, setting the flag control, assigning the
position and velocity pointers, and implementing PID gains.

Setup of a Fifth Motor Using Opt-12 on the Clipper Board
The DSPGATE2A supplemental channels are set with I6800-6807. Set these to the same values as
specified for the filtered PWM outputs (leave I6804-I6807 at default).
Example Turbo PMAC script code for motor 5:
The encoder decode I-variables are I68n0-68n9 (n = supplementary channels 1 and 2). Set these for your
encoders as normal. Note there are no direct inputs for flags so capture I-variables are not used. The
Output Command Registers (Ixx02) now must point to the DSPGATE2A 3rd Channel Outputs at $78414
and $7841C first and second supplemental registers respectively. The addresses of the DSPGATE2A
Counters/Timers used in the encoder conversion table are $78410 and $78418 first and second
supplementary registers respectively. When using the OPT-12 filtered PWM DAC on the hand-wheel port
use the second output at $7841C. The encoder counter registers are at:
Mxx->X:$78411,0,24,s // first counter register
Mxx->X:$78419,0,24,s // second counter register
Flags access through JOPTO port.
The OPT-12 channel may also access its machine I/O such as the overtravels, home, and fault flags for
one motor only. This is done through the JOPTO I/O lines (J9), by changing their function so that they
would act as Home / Pos / Neg / User flags for only the first channel of the two supplemental channels;
there are no flags for the second channel since these pins of the general I/O port of the PMAC2 gate2 are
not brought out in this board. The following example sets up the OPT-12 for two motors (#9 and #10) of
pulse and direction control with full machine I/O on motor #9.

LASER CONTROL OUTPUT
Clipper’s Option 11 consists of a programmable lattice chip which can be programmed based upon
customer’s requirements. The main objective for this option is to be used as a laser controller. Different
programs can be loaded in this chip based upon customers’ requirements and each code will be designated
an alpha-numeric suffix after options number if the code is developed by Delta Tau and can be ordered at
a later time with the same suffix.
Clipper’s option-11A is developed as a general command signal needed for CO2 lasers. Usually CO2
lasers require a few digital I/O signals in order to control the status and mode of the laser and a control
signal, which based upon the signal features controls the output power of the laser. The laser can be in a
few different modes:
Disabled
Standby
Active
Controlling between disabled mode and other modes is usually done through a digital output, either
directly if the device is TTL level or it would have to be done through a relay system. The difference
between the “Standby” mode and “Active” mode is because of the signal type and shape. Usually in order
to control the output power of the laser, a PWM (Pulse Width Modulation) signal is used and the positive
duty cycle of the signal indicates the output power of the laser, varying from 0 to 100%. However, in
order to ensure immediate response from the laser when an output is required, the gas needs to be kept
ionized. This can be achieved by outputting a PFM signal. The frequency and duty cycle required for each
of these modes differs based on the laser model and size and should be adjusted accordingly.
Assuming the following graph is the laser output response to a step command, the frequency of the
modulation can be selected.
As you can see, the rise time for the laser is about 126μsec. This means in order for our modulation to
fully cover the 0 to 100% range of the output, the frequency should be set close to 1/126μsec = 7936 Hz
or 8kHz. The tickle pulse is required in order to reduce the time between the change of command to PWM
and actual output of the laser. However calculating the signal requirements for the Tickle pulse is

dependent on the laser and differs for different manufacturers. For example the laser shown in the above
graph, requires a 5kHz signal with 0.5% duty cycle as its Tickle pulse.
In the next section we will use this laser specific information to set up Option-11A. Please note that the
values and settings here are just an example and your values might be different. Please refer to your laser
documentation or contact the manufacturer for detailed information about your specific laser.
Understanding Option-11A Capabilities
Option-11A has been programmed to include a few logical gates controlling the output signals. In general
there are a few signals available from the Clipper as inputs to the Lattice chip.
Laser Control Output 62
Turbo PMAC Clipper Hardware Reference Manual
The following logic circuit is programmed as the Option-11A into the Lattice chip:
As you can see, the idea is to switch the output between PWM_B signal and PFM signal based upon
either of the EQU outputs. EQU outputs are fast responding outputs which can either be activated
manually or based upon position compare feature of the PMAC. CTRL outputs control which of the
EQUs or what combination of EQUs will be used to control the output mode.
As an example, if a user wants to use EQU1 to switch between the Tickle pulse (PFM) and Output mode
(PWM), then CTRL0 must be turned on. As a safety measure, no output will be generated unless at least
one of the CTRL outputs is set to 1.
Clock Settings
The clock used for PWM is related to the Max Phase Clock, which is used to generate the Phase and
Servo clock, selecting an appropriate PWM frequency which satisfies both the laser requirements and
servo requirements can be challenging, especially if user is trying to use Filtered PWM outputs as DAC
outputs for amplifier commands.
In most of the applications, the PWM frequency is a set value and is not change at all, however in some
applications this is not the case and the PWM has to change based upon the material being cut or worked
on. If you are required to change the PWM based upon the material, you won’t be able to use the filtered
PWM outputs directly available from the Clipper board and you have to use ACC-8ES (Analog Servo
Interface) in order to get the DAC outputs for servo amplifier commands.
If the PWM frequency required for the laser is less than 30kHz required for the Filtered PWM outputs,
which mostly is the case, then the PWM frequency of the DSPGate1 (30kHz) should be divisible by
PWM frequency of the DSPGate2 which is used for generating the laser output signal. The clock source
on the Clipper, by default, is the DSPGate1, which in this case needs to be changed to DSPGate2. In order
to change the clock source, the following steps should be followed carefully in exact explained order or
else you may cause a watchdog.
Switching the clock source:
1. Set I19=6807.

Note
Please Set I28=1 and issue a SAVE and $$$ before the following
settings become active. The I28=1 will disable the DISPLAY output
port which in this case will over-write the CTRL outputs.
This will change the clock source from DSPGate1 to DSPGate2. Once the clock source is switched, the
following settings will give you different PWM frequencies on the laser output while keeping the 30 kHz
PWM requirement for Filtered PWM outputs:
Controlling the output
This section includes the memory address settings that you would need in order to change the PWM duty
cycle, PFM frequency, EQU output mode and EQU selection.
Based upon the settings above you can change the PWM duty cycle by changing the value of
PWM_CMD_VAL and the PFM frequency by changing PFM_CMD_VAL. The duty cycle of the PFM signal
however will be changed based upon I6804 and I6803 settings.
PFM width = I6804 / PFM Clock
The EQU can be turned on and off manually to switch the output mode:
EQU on: M112=1 M111=0
EQU off: M112=0 M111=0
Also, Position Compare function can be used to control the EQU output. Please refer to Turbo User’s
Manual for detailed information about position compare functionality and settings.

Watchdog Timer
On a Turbo PMAC Clipper, the watchdog timer trigger illuminates the red WD LED and interrupts
communication. It occurs if any of the following applies:
PMAC CPU over-clocked:
In this mode, the CPU signals that is has been overloaded with computation and cannot
accomplish tasks in a timely manner. e.g. bad programming such as an infinite loop, or too much
computation (Kinematics) requiring faster CPU option.
Wrong clock settings:
In this mode, the user has downloaded or written bad values to clock setting parameters.
Logic power supply +5V failure:
In this mode, the 5V logic power supply has failed. Check and monitor the 5VDC power.
Downloading wrong configuration file (I4900):
In this mode, the user has reloaded a configuration file uploaded from a 4-axis unit (Servo IC 1
parameters set to zero) into an 8-axis unit, thus writing zero to the second Servo IC clock
parameters. Commenting out variables I7100…7106 (or forcing them to hold the same values as I7000…I7106) eliminates the watchdog problem.
