Power Clipper between it and the ACC-24S3. Two of these small stack boards can be installed on top of
the ACC-24S3.
The ACC-8AS can be stacked on top of either the Power Clipper or the ACC-24S3 to provide 4 channels
of 16-bit “true DAC” output with two DACs per channel. This board is mainly used for very high-
precision servo applications that require more resolution than the filtered-PWM analog outputs on the
Specifications 13
Power PMAC Clipper User Manual
Power Clipper and the ACC-24S3. The dual-phase DAC outputs support the “sine-wave output” control
mode where brushless motor commutation is performed by the Power PMAC.
The true-DAC outputs of the ACC-8AS can be used simultaneously with the filtered-PWM analog output
on the same channel of the Power Clipper or ACC-24S3 without interference.
The ACC-8FS can be stacked on top of either the Power Clipper or the ACC-24S3 to provide 4 channels
of 3-phase direct-PWM output through Mini-D 36-pin connectors to “power block” amplifiers. This board
is mainly used for applications where the Power Clipper is performing both the commutation and digital
current loop closure for brushless motors.
The 3-phase PWM outputs of the ACC-8FS cannot be used simultaneously with the filtered-PWM analog
output on the same channel of the Power Clipper or ACC-24S3. However, they can be used
simultaneously with the PFM (pulse-and-direction) outputs of the same channel of the Power Clipper or
ACC-24S3 without interference.
The ADC inputs passed through the ACC-8FS can be used simultaneously with the Option 12 ADCs on
the Power Clipper or ACC-24S3 without interference.
ACC-8TS Bridge Stack Board to ACC-28B ADCs
The ACC-8TS can be stacked on top of either the Power Clipper or the ACC-24S3 to provide a flat-cable
interface to one or two ACC-28B 4-channel 16-bit ADC boards.
The ADC inputs passed through the ACC-8TS can be used simultaneously with the Option 12 ADCs on
the Power Clipper or ACC-24S3 without interference.
The ACC-51S can be stacked on top of either the Power Clipper or the ACC-24S3 to provide 4 channels
of sinusoidal encoder interpolation with 16,384 states per line.
The sinusoidal encoder inputs passed through the ACC-51S cannot be used simultaneously with the main
quadrature encoder inputs of the same channel of the Power Clipper or ACC-24S3 without interference.
However, it is possible to pass digital quadrature signals through the ACC-51S.
ACC-84S 4-Channel Serial Encoder Interface Stack Board
The ACC-84S can be stacked on top of either the Power Clipper or the ACC-24S3 to provide 4 channels
of serial-encoder interface. The ACC-84S can be ordered from the factory with a single encoder protocol
installed from the following list:
EnDat2.2 with additional information, no delay compensation
BiSS-B/C
Yaskawa II/III/V with position reset and fault clear
Tamagawa FA-Coder with servo clock output
Matsushita (Nikon D)
Mitsubishi
SSI (no capabilities over Power Clipper’s built-in interface)
Panasonic (no capabilities over Power Clipper’s built-in interface)
Mitutoyo (no capabilities over Power Clipper’s built-in interface)
Specifications 14
Power PMAC Clipper User Manual
The serial-encoder inputs on the ACC-84S can be used simultaneously with the serial-encoder input on
the same channel of the Power Clipper or ACC-24S3 without interference.
Clipper 4-Channel Breakout Board
The Clipper 4-Channel Breakout Board can be stacked under the Power Clipper board to provide discrete
connectors for each channel and each I/O functionality. It also provides optical isolation and driver
circuitry for axis flags and general-purpose I/O.
The Clipper 4-Channel Breakout Board cannot be used to provide connections for the ACC-24S3 Axis
Expansion Board.
Clipper 4-Channel LV Stack Amplifier
The Clipper 4-Channel LV (Low-Voltage) Stack Amplifier can be stacked under the Power Clipper board
or its 4-Channel Breakout board to provide the power amplifier circuitry for 4 motors with up to 60VDC
supply and a rating of up to 5A(rms) continuous, 15A(rms) peak. Each motor can be 1-phase (e.g. DC
brush motor), 2-phase (e.g. stepper motor), or 3-phase (e.g. brushless servo motor).
The Clipper 4-Channel LV Stack Amplifier cannot be used to provide the power stage for the ACC-24S3
Axis Expansion Board.
ACC-28B 4-Channel 16-Bit ADC Board
The ACC-28B provides 2 or 4 channels of 16-bit A/D converters on a DIN-rail mountable board. It can
be connected to the Power Clipper or ACC-24S3 by flat cable through an ACC-8TS bridge stack board.
ACC-34 Family Multiplexed I/O Boards
The ACC-34 family of multiplexed I/O boards each provide 32 general-purpose digital inputs and 32
general-purpose digital outputs. Up to 32 of these DIN-rail mountable boards can be connected to the
JTHW multiplexer port on the Power Clipper through standard flat cables. Due to the multiplexed access
and serial data transfers, these I/O points cannot react as quickly as the I/O points on the Power Clipper
itself.

Power PMAC Clipper User Manual
RECEIVING AND UNPACKING
Delta Tau products are thoroughly tested at the factory and carefully packaged for shipment. When the
Power 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 Power 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 Power 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 Power PMAC Clipper:
The components built into electrical equipment or machines can be used only as integral
components of such equipment.
The Power PMAC Clipper must not be operated on power supply networks without a ground or
with an asymmetrical ground.
If the Power PMAC Clipper is used in residential areas, or in business or commercial premises,
implement additional filtering measures.
The Power 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 Power PMAC Clippers with the standards for industrial
areas stated in this manual, only if Delta Tau components (cables, controllers, etc.) are used.
Receiving and Unpacking 18
Power PMAC Clipper User Manual
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 Power 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 Power PMAC Clipper should be mounted on a
smooth, non- flammable vertical or horizontal surface.
At least 10 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 Power 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.
If the Power 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).

The standard encoder inputs on the Power 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.
