Introduction 1
INTRODUCTION
The PMAC Demonstration Box is a general-purpose system consisting externally of a control panel
(ACC-16D) or an I/O simulator module (ACC-21S) with 4-axis limit switches, four or eight motors with
two-tone knobs attached to the motor shafts (for easy visual detection of motion), and communication
interface connectors on the back. Internally, the box consists of a +24V, 15V and a +5V DC power
supply, four or eight DC brushless motors with HP encoders, four or eight motor driver (ACC 8D option
4 or 4A), and one or two PMAC terminal block boards (ACC-8D). Another option would be a MACRO
interface stack so the demo box can be used with a PMAC2 Ultralite or an optional PMAC-PC controller
board which can be mounted either internally or externally and necessary wiring to the external
connectors.
This is useful for demonstration purposes to illustrate PMAC’s features and for both product development
and normal operation.
PMAC Description Summary
The bus-based Programmable Multi Axis Controller (PMAC-STD) is a DSP-based high-speed closed-
loop digital servo controller capable of controlling up to eight individual or coordinated axes and driving
a wide variety of motor types. As many as 16 PMAC cards may be used in a system to control a
maximum of 128 axes.
Control Panel (ACC-16D) Description
The control panel (ACC-16D) is a general-purpose operator interface device for PMAC 1 family
controllers. This control panel is useful for both development and normal operation applications.
The control panel provides a means for using PMAC’s dedicated hardware control inputs and display
outputs. It has nine toggle switches for jog, step, run, etc., a 10-way rotary switch for motor/coordinate
system select; a handwheel encoder, and an analog potentiometer that can be used as an input to PMAC’s
on-board voltage to frequency converter. A separate frequency generator may be input to any of PMAC’s
encoder channels and also an 80-character LCD display.
The control panel communicates to PMAC through PMAC’s JPAN (J2) port and its JDISP (J1) port.
Control panel functions are summarized in the next section. For more information, refer to the ACC-16D
User manual.

Note:
When I2=1, disabling normal control board operation, IPOS and FERR1 reflect the
status of the host-addressed coordinate system.
Selector (Rotary Switch):
Positions 1-8: Selects one of the eight possible motors and one of the eight possible coordinate systems
simultaneously. When the RUN switch is flipped, a &n (where n is the corresponding number of the
rotary witch) command is effectively issued before the R (RUN) command is issued. When the JOG
switch is used, a #nJ+ or #nJ- command is issued, thus jogging the corresponding motor. However, this
selector switch does affect the motor or coordinate system addressed by the host.
Position OFF: With the rotary switch in this position, the entire switch panel is disabled, i.e. all the
switches are ignored by PMAC. This can be accomplished also through software by setting I2-1 in
PMAC (for PROM versions 1.07 and later).
Position ALL: With the rotary switch in this position, the entire panel is enabled.
Note:
The Bn command is not sent before the R command when the RUN switch is
flipped. Setting I-Variable I2 to 1 and writing a PLC program to implement the
switch functions will reprogram the switches to do this.
DIR Switch:
Direction (CW or CCW) of A/B Quadrature frequency generator. When the FREQ-H/W switch is in the
FREQ position, the handwheel is disabled and the frequency generator is substituted for output on the A
encoder channel. This switch controls the direction sent (CW or CCW) over the encoder channel. This
signal must be connected to the ENC2 counter by jumpering E22 and E23 on PMAC.
STEP Switch:
Execute program one step at a time. Also used to stop a continuous run. Flipping this button issues a
&nS (STEP) command, where n is the corresponding coordinate system number as selected by the
Selector rotary switch.
RUN Switch:
Execute program in normal, continuous mode. This button issues a &nR (RUN) command, where n is the
corresponding coordinate system number as selected by the Selector rotary switch.
PRE JOG Switch:
Jogs the corresponding motor as indicated by the Selector rotary switch to its previous position. This
button is similar to issuing a #nJ command to PMAC, where n is the selected motor number.
HOME Switch:
Homes the corresponding motor as indicated by the Selector rotary switch to its previous position. This
button is similar to issuing a #nHM command to a PMAC, where n is the selected motor number.
Acc-31 User Manual
4 ACC-16D Layout
HOLD Switch:
Feed Hold. This button issues a feed hold for the corresponding coordinate system as indicated by the
Selector rotary switch
ABORT Switch:
Stops all motion programs or other moves in the corresponding coordinate system as indicated by the
Selector rotary switch. This is similar to issuing a &nA command to PMAC.
H/W:
Hand Wheel Encoder HEDS 7501. Typically,256 lines per revolution, A/B Quadrature. The H/W
encoder input may be multiplied by 1, 2 or 4 by PMAC. Also, the H/W encoder may be scaled to
represent any number of encoder counts to the motor. Usually, there will be motors doing position
following of this hand wheel using Ix05 and Ix06 (where x is the motor number). The signal must be
connected to the ENC2 counter by jumpering E22 and E23.
Frequency Pot:
Controls the pulse train frequency from 0 to 100KHz when the FREQ-H/W switch is flipped to the FREQ
position. It generates A/B Quadrature pulses, simulating an encoder. Use of this signal is the same as for
the hand wheel (i.e. using ENC2 by jumpering E22 and E23).
Feedrate Pot:
Controls feedrate by generating a DC voltage from 0 to 10V. This variable voltage is applied to pin 20 of
J2 (JPAN, the 26-pin connector) on PMAC. To actually implement this pot for feedrate control, install
jumpers E72 and E73 on the PMAC board and set the time base source address I-variable (Ix93 for
coordinate system x) to 1833($729).
JOG +/- Switch:
Jogs a motor. When this switch is flipped upward, the corresponding motor as indicated by the Selector
rotary switch is jogged into the positive direction. A #nJ+ command is issued. Similarly, when this
switch is flipped downward, the same selected motor is jogged in the negative direction, a #nJ-
command is issued, where n is the selected motor number.
FREQ-H/W Switch:
Selects between the internal frequency generator and the hand wheel. When the FREQ-H/W switch is in
the FREQ position, the hand wheel is disabled and the frequency generator is substituted for output on the
A/B encoder channels (pins 16 and 22 on J2).
PWR ON/OFF Buttons:
System power control. This is a relay switch which controls power and will turn off automatically when
the watchdog timer on PMAC has tripped.

ACC-21S Layout 5
ACC-21S LAYOUT
The ACC-21S, I/O Simulation Module, can be used in the development phase of an application if PMAC
is to write or read to and from other devices. ACC-21S communicates to PMAC via PMAC’s J5
(JOPTO) port. When the demo box comes with this accessory, it also has a 4-axis limit switch panel (P/N
603294-01). The panel provides LIM and a HOME switch for every single one axis.
Note:
With PMAC2 controllers, ACC-8E is needed to use this module.
PMAC’s JOPTO connector (J5 on PMAC PC, Lite, and VME) 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. ACC-21F is a six-foot cable for this purpose. The PMAC-
STD has a different form of this connector from the other versions of PMAC. Its JOPT connector (J4 on
the baseboard) has 24 I/O, individually selectable in software as inputs or outputs. The rest of this
discussion does not pertain to the PMAC-STD port, unless specifically mentioned.
For more information of how to use and setup this module, refer to the ACC-21S User manual.
MACRO Interface Description
To use the demo box with a PMAC2 Ultralite/MACRO station system, order the MACRO interface
option. This option comes with a MACRO interface CPU, a 4-Axis stack board, ACC-2E (for four
motors, if it is an eight motors demo box, two ACC-2Es are needed), and ACC-3E for 48 bits of I/O. The
connection between ACC-2E and the demo box is with a flat cable (ACC-8D Option V) from the P2 (96
pin) of the ACC-2E to the JPMAC (60 pin) of ACC-8D.
For more information, see the MACRO accessories manuals.

Rear External Connectors
The rear panel of the demo box consists of several external connectors. Depending upon a particular
demo box configuration, the connectors may be arranged differently. However the connectors provide the
same function (and have the same pin configurations) for all boxes. The connectors are as follows:
Limit Switches Connector (LIM)
This is circular shaped 14-pin female connector usually located near the bottom center on the rear panel
of the demo box. Eight of these pins are connected to the LIMIT switch inputs for motors 1 through 4 of
PMAC, and another four are connected to the HOME FLAG inputs for motor 1 through 4. They are all
wired to the internal terminal block, which is also wired to PMAC’s 60-pin machine cable connector
(JMACH1). This can be changed by rewiring the terminal block. Included with the demo box is a mating
male connector, with its pins 1 through 13 all wired to pin 14, the analog ground. Thus, with this shorting
plug installed, all the limits and home flag signals are grounded.
The pins are assigned as follows:

The part number for the mating connector is AMP 206044-1. The part number for the connector’s hood
is AMP 206020-1.
Machine Connector (JMACH)
This is the 60-pin machine connector which connects to, via a 60-pin cable, PMAC’s machine connector,
P2 (JMACH1 or JMACH2). Among other things, this connector provides the encoder signals, position
limits, home flag signals, and the DAC output voltages for four axes (either for motors 1-4 or 5-8). Since
PMAC is external to the demo box, it is connected to the demo box via this connector. For individual pin
descriptions for this connector, refer to the PMAC Connector Description section in the PMAC Hardware
Manual. PMAC cannot servo the motors without this cable connected.
Display Connector (DISP)
This is a 14-pin connector provided for sending data to the LCD character display on the front control
panel. The 40 character x 2 line LCD display unit can display position, velocity, following error, status,
etc. for any axis, or can display any text message. Refer to the DISPLAY command in the PMAC User
Manual. This connector attaches to J1 (JDISP) on PMAC via a 14-pin cable. For individual pin
descriptions for this connector, refer to the PMAC Connector Description section in the PMAC Hardware
Manual.

Control Panel Connector (JPAN/CNT-PNL)
This is a 26-pin connector which provides external access to the front control for PMAC. Refer to the
Control Panel Description section of this manual for details about this panel. This connector is connected
to PMAC’s J2 (JPAN) via a 26-pin cable. For individual pin descriptions for this connector, refer to the

Terminal Blocks 11
Demo Box Power Supply Plugs
Setup Type 1
PMAC +5V is provided from the demo box’s internal +5V power supply. This is always the case if the
PMAC is installed inside the demo box. It is also the case if the PMAC is standalone outside of the box,
but with no separate power supply. In either of these cases, the solid black power plug should be used in
the VIN/VOUT (pins 4 and 8 connected) socket. Use of this plug causes the box’s internal +5V supply to
provide power to PMAC through the 60-pin flat cable to PMAC’s JMACH connector.
Setup Type 2
PMAC +5V is provided from an external power supply. This is always the case if the PMAC is in a bus-
based system, such as a PC ISA or PCI bus, or a bus-based PLC (e.g. the GE FANUC 90/70). It is also
the case if a standalone PMAC is receiving +5V power through its bus connector or its on-board terminal
points. In either of these cases, the power plug with the white stripe should be used in the VIN/VOUT
(pins 4 and 8 not connected) socket. Use this plug prevents the demo box’s internal supply from
powering PMAC and so allows the external supply to power PMAC and the box’s encoders.
Setup Type 3
If using PMAC2 Ultralite and the MACRO interface CPU stack boards in the Demo box, then the solid
black power plug should be used in the VIN/VOUT (pins 4 and 8 connected) socket. Use of this plug
causes the box’s internal +5V supply to provide power to the MACRO interface CPU and its accessories.
Sometimes is good to also connect the +5V to one of the boards of the stack with extra cables, through the
TB Phoenix connector.
Important Note:
The PMAC Demonstration Box comes equipped to be able to handle several
different power supply configurations. It is important to configure the box
properly for a particular application. The key issue is the source of the +5V that
supplies the digital circuitry on PMAC. The plugs that insert into the VIN/VOUT
socket on the back of the demo box are used to control the source.
