Reset not possible
Wait until the fault response has ended.
(Attention: not in parametrising mode)
A reset was previously ignored.
Extended diagnostics required, e.g. with FCT.
Use reset counter (Integer type) in order to limit the maximum number of resets.
The CMAX always tries to reset all active fault messages. Acknowledging several times is not necessary.
There may, however, be subsequent errors after acknowledging. Cancel acknowledgement after more than
3 trials and perform extended diagnostics, e.g. with the FCT.
Rising edge means that CCON.RESET is pending for at least as long as is required for the CMAX to clearly
recognise it. This period depends on the CPX node used and the bus cycle time. Recommendation:
Time > 10 msec
Use timer in order to limit the maximum response time of the CMAX. Depending on the fault number, various
responses are triggered in the CMAX after reset. New initialisation of the axis string takes the longest (max.
3 seconds).
Reset successful
