Acknowledging
malfunctions
Reported malfunctions must be acknowledged with
CCON.RESET. It might be necessary to remedy the cause of
the malfunction.
1. Positive edge on CCON.RESET.
2. Wait 3 s (depending on the malfunction, CMAX requires a
maximum of 3 seconds, e.g. for initialising the axis).
3. Check whether the malfunction has been remedied:
if SCON.FAULT = 0: ok
if SCON.FAULT = 1:
Check the malfunction number and eliminate any
cause. See section 5.2.4.
Fundamentally, CMAX always attempts to acknowledge the
currently pending malfunctions. If there are several malfunc
tions active at the same time, the behaviour is directed to
ward the most serious malfunction.
If there are several malfunctions registered and one
malfunc
tion can be cleared by resetting, but the others cannot, the
remaining malfunctions are displayed after the reset.
Warnings
Events and statuses which can potentially impair operation
are signalled as a warning. A list of warning messages can be
found in section 5.2.4.
Warning reaction In the case of warnings, CMAX does not have the Malfunc
tion" status, but continues to have Ready" status.
Warnings are reported with SCON.WAR N = 1. There is
no
effect on the sequence control or the axis.
Acknowledging warnings SCON.WARN is set = 0, depending on the warning:
with the positive edge at CCON.START or CCON.RESET
(as far as the cause has been remedied).
