Faults and Alarms

If a fault or alarm condition exists, it will be annunciated on the keypad and recorded in both
the Fault and Event Logs. External hardwire indicators are also set as defined in the System
Program. PLC access is available for all faults/alarms.
All faults will immediately remove power from the motor and inhibit the drive from running,
resulting in the motor coasting to rest. Some faults that are user-defined can control the drive
response via the system program. Alarms are annunciated and logged, but usually do not
inhibit the drive from operation. Faults are either detected via direct hardware sensing or by
software algorithm.
The NXG control includes both internal faults and alarms and the ability to define "User
Faults" via the SOP, which can be set as either faults or alarms.
Regardless of the source, all faults are user-friendly messages displayed in plain text where
no fault "code" numbers are used. User Fault/Alarm messages allow the SOP writer to
define the fault as desired, with a 24-character limit.
