Introduction 9
INTRODUCTION
The Power Clipper is a 4 axis motion controller combining the intelligence and capability of a Power
PMAC CPU with the convenience and savings of a low cost platform that is 100% hardware compatible
with its Turbo PMAC family member the Turbo PMAC Clipper.
It supports virtually any type of feedback device (with the optional ACC-84S and ACC-51S) and can
drive directly the following types of motors with the optional Clipper Drive Stack:
3-phase AC/DC brushless servo (synchronous) -- rotary/linear
2-phase stepper
DC brush
Note
The Power Clipper can also provide pulse and direction PFM output
signals to third-party stepper drives.
The number of axes in a Power Clipper application can be expanded to 8 with the optional ACC-24S3.
The Power Clipper comes with 32 general-purpose digital I/O points which can be expanded through the
optional ACC-34AA, ACC-24S3 or EtherCat. These can be configured as input or outputs in groups of
eight. The default factory settings are 16 inputs and 16 outputs.
The outstanding trajectory planner, built-in software PLCs (programmable in Power PMAC script and / or

Power Clipper between it and the ACC-24S3. Two of these small stack boards can be installed on top of
the ACC-24S3.
ACC-8AS 4-Channel 2-Phase 16-Bit True-DAC Stack Board
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

Power PMAC Clipper User Manual
Specifications 14
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.
ACC-8FS 4-Channel Direct-PWM Interface Stack Board
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.

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.

Digital Power Supply
The +5V and ground reference lines from the power supply should be connected to TB1 terminal block of
the Power PMAC Clipper board using 18 AWG stranded wire. The power requirement (± 5%) is:
+5 V (20W) @ 3.5 A (Four-channel configuration with a typical load of encoders)
+5 V (20W) @ 5.5 A (Eight-channel ACC-24S3 configuration with a typical load of encoders)
Note
Clipper base board requires 2.75A with no other connections. Size
your application accordingly to your encoder load. The above assumes
typical encoder loads at ~100mA per encoder.
DAC Outputs Power Supply
The ±12V lines from the supply, including the ground reference, can be brought in from the TB1 terminal
block.
+12 to +15 V (4.5W) @ 0.30 A (Four-channel configuration with a typical DAC load)
-12 to -15 V (3.8W) @ 0.25 A
+12 to +15 V (4.5W) @ 0.50 A (Eight-channel configuration with a typical DAC load)
-12 to -15 V (3.8W) @ 0.45 A
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 Power PMAC Clipper and can be connected from the TB1 terminal block.

Power PMAC Clipper User Manual
Mounting 19
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.
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]).
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).
