Note About Servo Alarm Output:
For normal operation, the alarm output from the drive should be ON
(active). When the Alarm output is OFF (open circuit) the 7737 reads it as a fault condition. You can
override the fault condition by installing the jumper on J4 Drive Error override. We recommend you
install the jumpers for all unused Drive-Error signals.
