Cause : That hardware fault (r0947 = 22 and r0949 = 1) caused by the following events:
(1) DC-link overcurrent = short circuit of IGBT
(2) Short circuit of chopper
(3) Earth fault
(4) I/O board is not properly inserted
Since all these faults are assigned to one signal on the power stack, it is not possible to establish which one actually occurred.
Diagnose & Remedy
Check the I/O board. It has to be fully pressed home
