The mains input is a filtered IEC inlet.
The
MOTOR
connector has outputs from the PM570-Evo2 stepper drive to connect to a
bipolar stepper motor.
WARNING! Serious damage will occur if the motor is connected or disconnected
whilst the power is switched on. Allow 30 seconds after switching off.
The
LIMITS/DATUM
connectors have inputs for the Upper and Lower Limit switches, a
Datum Approach switch and a Datum Stop switch. The connections to the Limit switch
inputs must be
made
for normal operation of the PM600 controllers.
Limit switches must not be used as a safety device or part of a safety system for
ensuring the safety of persons
The
ENCODER
connector is for the position encoder input. It has a +5V supply to
energise the encoder, complementary
quadrature
inputs and complementary
index
inputs.
The
JOG A
and
JOG B
connectors have inputs for Jog pushbuttons, a Joystick control
and data connections for a JC809 Jog Box.
They have connections for Jog, Jog- and Jog Fast pushbuttons compatible with a JC100
Jog Box and +5V, 0V Joystick input and Joystick centre tap compatible with a JC400
Joystick. The JC100 and JC400 may be plugged into either connector.
If using a JC809 Multi axis jog box, the axis address that is assigned to Jog is set on the
MSB867 interface board using a rotary switch (see section 5.2). The JC809 can be
connected to other axes by using a ‘Jog daisy-chain’ cable plugged into the vacant
JOG A
or
JOG B
connector. The Jog Terminator supplied with the JC809 must be plugged into
the vacant connector in the last axis in the daisy-chain.
The
I/O
connector has inputs and outputs from PM600’s
Read
inputs and
Write
outputs.
There are also connectors for
RS232 IN
for connecting to the computer or terminal that
supplies the control data and
RS232 OUT
for connecting either to a subsequent control
rack (
daisy-chain
) or to an RS232 terminator. These connectors can also be configured for
RS485 communications (see section 1.2).
Note:
The RS232 Terminator supplied with the control system must be fitted to the last
unit in the
daisy-chain
. This allows both replies from, and commands sent to, the controller
to be echoed back.
WARNING! To avoid overheating, the vents in the top and bottom of the unit must
be unobstructed at all times.
