Chapter 5 - Fault Tracing
When the drive control diagnostics detect an unusual operating condition, the drive initiates a visible
notification on the keypad. The keypad displays the code, the name and a short description of the fault or
alarm.
Notifications vary in consequence and required action. Faults make the drive stop and require a reset of the
drive. Alarms inform of unusual operating conditions, but the drive will continue to run. Infos may require
resetting but do not affect the drive’s operation.
For some faults, you can program different responses in the application. See the parameter group Protections.
The fault can be reset with the Reset button on the control keypad or via the I/O terminal. The faults are
stored in the Fault history menu which can be browsed. Fault codes are outlined in the following table.
NOTE:
For a fault condition, contact Technical Support.
Always write down all texts and codes on the keypad display and a description of
the problem together with the Drive Info file.
