DuRApulse GS4 AC Drive User Manual – 1st Ed, Rev A - 10/20/2017
The status of the drive is reported back in registers 2100h~2110h (48449~48465 decimal). The six
most recent faults are found in P11.04~P11.09 (0B04h~0B09h, 42821~42826 decimal). See Chapter
5 for more detailed explanations of these registers.
