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.
