4.2.4 Reset types: Behaviour in the event of fault acknowledgement
Depending on the type of the fault, acknowledgement leads
to various actions in the CMAX, in order to delete the active
fault message and possibly quit the fault status.
Type Description Example
R Acknowledging (reset)
The reset command deletes the message. The fault is then terminĆ
ated. It will only be reported once more if the command is repeated
without the cause of the message having been eliminated. E33: Target posiĆ
tion outside of the
software or hardĆ
ware end posiĆ
tions
F Acknowledge if cause eliminated (fix cause and reset)
The CMAX deletes the message provided the cause has been eliminĆ
ated. If the cause has not yet been eliminated, the message is not
deleted and the fault status is not quit. E51: Load voltage
of the controller
outside of the tolĆ
erance range (unĆ
dervoltage)
N Restart (new initialisation)
The CMAX restarts the axis after acknowledgement. In the course of
this, the controller is re−calculated. If necessary, the components
(sensor interface and valve) are re−commissioned. All fault messages
are deleted prior to restarting.
If no fault occurs during restart, the fault status is quit after the reĆ
start. Otherwise CCON.Fault is not reset. The maximum time for a
restart is 3 s. E60: Faulty comĆ
munication with
the valve or no
valve present
Poff Power off
Reset no longer possible, CMAX needs to be switched off. E72: system softĆ
ware error

CPOS.START (provided the cause was eliminated).
