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.
To clear the fault history (all of the Group 04, Fault History parameters):
1. Using the control panel in 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.
