Operation
8.2 Major Drive Faults and Alarms
8.2 Major Drive Faults and Alarms
The control senses all drive faults and alarms, either from direct hardware or via software
algorithms.
Use the following tables to quickly locate major causes of fault conditions. The tables also list
the type of drive response, if it is a fault (F), alarm (A), or both (F/A), and whether it can be
enabled or disabled using the SOP program (SOP), Menu, or if it is permanently enabled, i.e.
fixed in software.
Refer to the
various fault and alarm conditions:
Table 8-1 Fault / Alarm Types and Responses
Type Drive Responses
Fault
● All IGBT gate drivers are inhibited.
● Motor coasts to stop.
● The fault is logged. Refer to the Fault Log Menu (6210).
● The fault is displayed on the front panel.
● The keypad fault LED is ON.
● Most faults are logged to the Event Log.
User Faults
● The motor either ramp stops or coast stops depending on the content of the system program.
● The fault is logged. Refer to the Fault Log Menu (6210).
● The fault is displayed on the front panel.
● The keypad fault LED is ON.
● User defined faults are logged to the Event Log.
Alarm
● The drive does not necessarily revert to the idle state via a coast or ramp stop unless specifically
● The alarm is logged. Refer to the Fault Log Menu (6210).
● The alarm is displayed on the front panel.
● The keypad fault LED flashes.
8.2.1 Faults / Alarms Types / Responses
Existing fault or alarm conditions are annunciated on the keypad. The NXG Control software
and hardware sense faults and alarms and store them within the fault logger and the event
logger.
The cell control system logic, located on the cell control board in each output power cell, senses
cell faults. Each power cell has its own sense circuitry. The NXG Control software interprets
the cell faults and displays them and logs them based on the faulted cell and the specific fault
within the cell.
All sensed faults immediately inhibit the drive from running and remove power from the drive
to the motor. Some user-defined faults can control the drive response via the system program.
Alarms are annunciated and logged but usually do not inhibit the drive from operation.
