6-4 Interfaces

Digital Inputs

ULTRA 200 Series drives have active high, current sinking inputs,

which prevent disconnects and ground faults from activating a drive.

Two discrete input circuits types are available on the J1 connector.

Both circuits support logic type interfaces with 24 Volt, optically

isolated, single ended and active high, current sinking characteristics.

Dedicated Control Circuits

The ENABLE input interfaces with switch closures or sourcing type

outputs. The input channel sinks 4.5 mA nominal.

Selectable Circuits

INPUT 1, INPUT 2, INPUT 3, INPUT 4 and FAULT RESET operate

with switch closures or sourcing type circuitry. Each input channel

sinks 4.5 mA nominal. Selectable inputs are:

● Drive Mode Select

● Integrator Inhibit

● Follower Enable

● Forward Enable

● Reverse Enable

● Preset Select A

● Preset Select B

● Preset Select C

● Operation Mode Override

● Start Index

● Define Home

● Start Homing

● Remove COMMAND Offset
