Description of parameters

No supply voltage
Enabling of the diagnostics, for lacking or insufficient supply voltage L+.
Short circuit to ground
Enabling of the diagnostics if a short-circuit of the actuator supply (CHx) to ground occurs.
Maintenance switching cycles
You use this parameter to enable the maintenance interrupt "Limit value warning" when the
switching cycle limit is violated.
You configure the limit with the parameter "Switching cycle limit" for each channel CHx.
Switching cycle counter
Channel-by-channel enable of switching cycle counter (Page 13).
Wire break
Enabling of the diagnostics if the line to the actuator is broken.
Reaction to CPU STOP
Determines the reaction of the output when the CPU goes into the STOP state or when the
connection to the CPU is interrupted.
Switching cycle limit
Defines the limit channel-by-channel. If this value is exceeded, the "Limit value warning"
maintenance interrupt is signaled.
Enter an integer value between 0 and 16777214. Refer to the data sheet of the connected
actuator. We recommend that you do not enter this maximum value, but instead set it to 80%
or 90%, for example, so that you have enough time to replace the actuator as a preventive
measure.
