FM 452 Electronic Cam Controller
C79000-G7076-C452-04
No.
Diagnostic
Interrupt
Meaning
70
Hardware interrupt lost
Yes
Cause
A hardware interrupt event has been detected by the
FM 452 and cannot be signaled since the same event
has not yet been processed by the user program/CPU.
Effect
•
Cam processing switched off
•
Track outputs are switched off
•
With incremental encoders, synchronization is
deleted.
Rectification
•
Link OB40 into the user program
•
Check bus connection of the module
•
Deactivate process interrupt
•
Upgrade hardware and software to suit your
process requirements (for example faster CPU,
optimize user program)
144
Encoder wire break
Yes
Cause
•
Encoder cable cut or not plugged in.
•
Encoder has no quadrature signals.
•
Incorrect pin assignment.
•
Cable length too long.
•
Encoder signals short circuited.
Effect
•
Cam processing switched off
•
Track outputs are switched off
•
With incremental encoders, synchronization is
deleted.
Rectification
•
Check encoder cable.
•
Keep within encoder specification.
•
Monitoring can be temporarily suppressed at the
responsibility of the operator by setting appropriate
parameters in the parameter assignment user
interface.
•
Keep to the module technical data.
