If a fault shuts down the drive, proceed as follows:
1 Do not switch off the auxiliary power supply or try to reset a fault
message before all information at the time of the occurrence of the
fault condition has been saved.
2 Call up the Fault History Display on the CDP control panel.
For further information, see
Do not clear the fault buffer of the drive now!
3 Identify the fault and make a logbook entry.
Note the fault message displayed on the CDP control panel and look
up the fault message in the Alarms and Faults Troubleshooting Guide
for further information.
4 Save the content of the data logger when a PC is available that has
the DriveWindow or DriveDebug installed.
The data logger provides information (eg, waveforms of voltage,
current, torque) for efficient troubleshooting.
5 If a fault cannot be rectified, contact ABB service.
When calling ABB service, it is recommended to have the following
data available at the time when the fault occurred:
■ Operating, ambient and load conditions
■ Unusual events
After the fault has been rectified, start the drive as described in
- Operation.
