Integration in the Servo System / Interface Circuitry Examples Inhibit Input AZ drives feature an Inhibit Input pin that is used to either enable or disable the drive. By default, the Inhibit Input pin should be left open to enable the drive, and brought to Signal Ground to disable the drive. This logic can be reversed if jumper JE1 is removed, however.

The Current Monitor output should be measured relative to Signal Ground.

The Current Reference output should be measured relative to Signal Ground.
