History

For reference, the last three fault codes are stored into parameters 0401, 0412,

0413. For the most recent fault (identified by parameter 0401), the drive stores

additional data (in parameters 0402…0411) to aid in troubleshooting a problem. For

example, parameter 0404 stores the motor speed at the time of the fault.

The Assistant Control Panel provides additional information about the fault history.

See section Fault Logger mode on page 57 for more information.

To clear the fault history (all of the Group 04: FAULT HISTORY parameters):

1. Using the control panel in the Parameters mode, select parameter 0401.

2. Press EDIT (or ENTER on the Basic Control Panel).

3. Press UP and DOWN at the same time.

4. Press SAVE.

Correcting alarms

The recommended corrective action for alarms is:

• Determine if the alarm requires any corrective action (action is not always

required).

• Use the table in section Alarm listing below to find and address the root cause of
