Digital Inputs

ULTRA 100 Series drives have active high inputs, which prevent

disconnects and ground faults from activating a drive. The typical ON

time for an input to be recognized is 2.0 msec.

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

Both circuits support logic type interfaces with optically isolated,

single ended and active high characteristics.

Dedicated Control Circuits

The ENABLE input interface with switch closures or sourcing type

outputs.

Selectable Circuits

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

switch closures or sourcing type circuitry. Selectable inputs are:
