Function number 4828 + m × 64 + 0
m = module number (0 … 47)
Description Monitoring the Motion Terminal for the following error:
–
Short circuit or overload in sensor supply
–
Undervoltage at the valves U
VAL
The monitoring of the errors can be individually activated or deactivated.
Active monitoring has the following effect:
–
Error message at the CPX field bus nodes
–
Malfunction message in the VTEM diagnostic memory
Both types of monitoring can also be activated for the entire CPX terminal.
For details, see the manual of the CPX terminal
