)
), amp enable output, and amp fault input
Flags 5-Pin Screw Terminal Axis overtravel limits & home flag input
JOPT Output 11-Pin Screw Terminal Eight general purpose outputs
JOPT Input 11-Pin Screw Terminal Eight General purpose inputs
FLT
RELAY 3-Pin Screw Terminal PMAC Fault (Watchdog) Output (Normally closed
and
Normally open
Outputs)
JDISP 15-Pin D-Sub Connector PMAC Display Output (For use with any of the family of ACC12 Displays)
JPAN 25-Pin D-Sub Connector PMAC Panel interface connector. (Inputs such as: Axis Select, Jog, Home,
Run, Abort, Reset. Outputs such as: Following error, In position, buffer full.)
JTHW 25Pin D-Sub Connector PMAC Multiplexer port connector. Used for interconnection of additional I/O
(PMAC ACC27, ACC34), Thumb wheel inputs (PMAC ACC 18), and power
on position information.
JRS232 DB9 Connector
Standard RS232 Interface for communication to PMAC. (Non-functional
when optional RRS422 interface ordered, OPT-9LPP) . This serial
interface does not support multi-drop tri-state communication to
multiple PMAC-Packs.
JRS422 25-Pin D-Sub Connector Optional RS422 Interface for communication to PMAC. Supports multi-drop
tri-state communication to multiple PMAC-packs on single serial cable.
(Requires PMACPACK OPT-9LPP. JRS232 port is rendered non-functional.)
JANA 15-Pin D-Sub Connector Analog input port connector, only active when PMAC-Pack is equipped with
ACC28PP. Provides interface for 4 analog inputs, isolated power.
JEXP 50-Pin Box Header Expansion port for connection of ACC24EXP, PMAC ACC14, or other
PMAC accessories which connect directly to the microprocessor bus.
TBOUT 12-Pin Screw Terminal Four Channels of DC Motor Outputs, 48 V Amplifier DC bus input, dynamic
braking resistor output
JHW 9-Pin D-Sub Connector Inputs for one channel of incremental quadrature encoder feedback.
Switches and Indicators
PMAC-Pack is equipped with the following switches and indicators:
Communications
Switch Bank
This bank of 8 DIP-switches sets the serial communications baud rate. Additionally it controls the "card
address" for use in addressing multiple PMACPacks.
RE-INIT
Re-Initialization — This switch, if depressed on power up, reinitializes PMAC's software to the factory
default state. PMAC only concerns itself with the status of this switch upon power up. (The Switch is tied
to PMAC's "E51" Jumper).
PWR
The Green "Power" LED should illuminate when AC power is applied to PMAC-Pack.
WDT
The Red Watch Dog Timer LED will illuminate when there is a serious fault within PMAC. Consult
Chapter 4 of this manual for further detail on the conditions leading to this fault.
OPWR
The orange Opto Isolation Power LED embedded in the edge of the JOPT-OUTPUT connector will
illuminate when power (+12 to +24V) is applied to the O+V (pin 2 of the JOPT-OUTPUT port).
