FM 452 Electronic Cam Controller
C79000-G7076-C452-04
No.
Diagnostic
Interrupt
Meaning
145
Frame error absolute encoder
Yes
Cause
The frame traffic between FM 452 and the absolute
encoder (SSI) is erroneous or interrupted:
•
Encoder cable cut or not plugged in.
•
Incorrect encoder type
•
Encoder incorrectly set (programmable encoders)
•
Frame length incorrectly specified
•
Encoder supplies incorrect values (encoder
defective)
•
Interference on measuring system cable
•
Baud rate selected too high
Effect
•
Cam processing switched off
•
Track outputs are switched off
•
The last correct actual value remains unchanged till
the end of the next correct SSI transfer
Rectification
•
Check encoder cable.
•
Check the encoder.
•
Check the frame traffic between encoder and FM
452.
146
Missing pulses frame incremental encoder
Yes
Cause
•
Encoder monitoring has detected missing pulses.
•
Number of increments per encoder revolution is
incorrectly entered.
•
Encoder defective: Does not supply the specified
number of pulses.
•
Bad or missing zero marker.
•
Interference affecting the encoder cable.
Effect
•
Cam processing stopped
•
Track outputs are turned off
•
The synchronization is deleted.
Rectification
•
Enter the number of increments/encoder revolution
correctly.
•
Check the encoder and encoder cable.
•
Keep to shielding and grounding regulations.
•
Monitoring can be temporarily suppressed at the
responsibility of the operator by setting appropriate
parameters in the parameter assignment user
interface.
