COM (Input)

Opto Common input. Used

to Optically Isolate the In-

put when a separate supply

is connected. Connecting the

+5VDC will make the Inputs

Functional but the Inputs will

NOT be Isolated. Note COM

needs to be powered either

by a separate supply or the

+5VDC Pin in order for the In-

put/ Outputs to function.

Voltage: 3 - 24 VDC

Max Current: 20mA

DISABLE (Input)

Used to Disable drive. Active

Low. A closed connection to

GND will Disable the drive.

This is a Sink or Source Input

Voltage: 3 - 24 VDC

Max Current: 20mA

STEP (Input)

The Step output from a Pulse

Generator is Input into this

pin. Both an NPN and a PNP

type PLC can be used for this

input. Refer to Connection Di-

agrams for help

Voltage: 3 - 24 VDC

Max Current: 20mA

DIR (Input)

Used to switch Direction

of motor. Active Low. A

closed connection to GND will

change direction. This is a

Sink or Source Input.

Voltage: 3 - 24 VDC

Max Current: 20mA

+5 VDC (Input)

Internal +5VDC Output. If Op-

tical Isolation is not desired

then it can be connected to

COM Pin. DO NOT USE FOR

EXTERNAL CIRCUITRY!

Voltage: 5 VDC

Max Current: 80mA
