Table 7.2 Error Messages
MG33R302
Operating Instructions
•
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.
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.
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.
•
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.
