9 Controller (PID) tracking error too big
•
The difference between the desired setpoint position and the actual position
read via the encoder feedback has exceeded the limit specified in parameter
32-67 Maximum Tolerated Position Error .
•
Reasons:
- The encoder is not properly connected. Check the encoder
connection.
- The encoder is counting positive in the wrong direction. Switch A
and B channels if necessary.
- The PID controller settings are not properly optimised. Follow the
instructions for optimising.
- The limit specified in parameter 32-67 Maximum Tolerated Position
Error may be too low.
12 Reverse operation prohibited The motor has been operated in reverse direction while this was not allowed
according to the setting in parameter
32-68 Reverse Behaviour for Slave .
13 Forward operation prohibited The motor has been operated in forward direction while this was not allowed
according to the setting in parameter
32-68 Reverse Behaviour for Slave .
92 Error from encoder monitoring
•
Open or short circuit in accordance with the displayed indicator light.
•
An error is displayed even if no encoder is connected and the monitor is
active (parameter
32-09 Encoder Monitoring = [1] 3 channels .
