ACH550 User's Manual
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, a parameter 0404 stores the motor speed at the
time of the fault.
To clear the fault history (all of Group 04, Fault History
parameters), follow these steps:
1. In the control panel, Parameters mode, select parameter
0401.
2. Press EDIT.
3. Press the UP and DOWN buttons simultaneously.
4. Press SAVE.

of the problem.
