40501 Fault History 1 Read/Write Data is 2-bytes long, so is stored as H00OO.

Refer to the lowest 1-byte for the error code.

Perform write using the register 40501 batch-clears the faults history.

Set any value as data.

1 The communication parameter values are not cleared.
2 For write, set data as the control input instruction. For read, data is read as a VFD operating status.
3 For write, set data as the operation mode setting. For read, data is read as the operation mode status.
4 The signal within parenthesis is the initial setting. Definitions change according to the settings for P.180 to P182.
5 The signal within the parenthesis is the initial setting. Definitions change according to the settings for P.190 and P.192.
6 When P. 37 = 0.01 to 9998, this displays as an integer number.
