Acknowledging faults

Indicated faults need to be acknowledged with CCON.RESET.
It may be necessary to eliminate the cause of the fault first.

1. Positive edge on CCON.RESET.

2. Wait 3 s (depending on the fault, the CMAX requires at the

most 3 seconds, e.g. to initialize the axis).

3. Check whether the fault has been eliminated:

ć

if SCON.FAULT = 0: ok

ć

if SCON.FAULT = 1:
Check fault number, eliminate cause, if necessary, see
section 4.2.5.

The CMAX always tries to acknowledge all currently pending
faults. If several faults are active at the same time, the behavĆ
iour depends on the most serious fault.

If there are several faults pending and one fault can be deĆ
leted after a reset, but not any others, one of the remaining
faults is indicated after the reset.
