To select your input voltage, you need to set the discrete I/O
jumpers.

!

ATTENTION: To avoid damaging the PLC
Communications Adapter Board, you must set all
discrete I/O jumpers to the same input voltage applied
to the PLC Communications Adapter Board. The
voltage must be either 24V dc or 120V ac.

Set this discrete

I/O jumper:

To set this input:

To either:

DR EN

Drive Enable

24V dc or 120V ac

M THERM

Motor Thermoguard

24V dc or 120V ac

N STOP

Normal Stop

24V dc or 120V ac

X FLT

External Fault

24V dc or 120V ac

You can use jumper J3 on the PLC Communications Adapter Board
to either allow (enable) or not allow (disable) writes to Battery
backed Random Access Memory (BRAM).

Choose:

To:

EN (Enabled)

Allow writes to BRAM.

DIS (Disabled)

Not allow writes to BRAM.

Two terminal blocks, TB20 and TB21, are provided at the bottom of
the PLC Communications Adapter Board for discrete and analog I/O
wiring.

To make the connections more easily, you can pull apart the terminal
blocks when connecting the cables.

Both terminal blocks accept a maximum wire size of 3.3 mm

2

(12

AWG) and a minimum wire size of 0.60 mm

2

(30 AWG). Maximum

torque is 0.79 N–m (7 lb–in). Recommended control signal wire is:
