Operating Instructions
Meaning/cause
No errors detected.
•
A positioning command to a certain position has been issued while the home
position is not defined.
•
Clear the error and complete a homing sequence successfully before issuing
the next position command to the application.
•
The positive hardware switch input has been activated.
•
The application has hit the positive limit marker switch. Alternatively, the
connection to the limit switch has been lost or the limit switch is defective.
•
The negative hardware switch input has been activated.
•
The application has hit the negative limit marker switch. Alternatively, the
connection to the limit switch has been lost or the limit switch is defective.
•
A motor command has caused the software limit switch to be activated. The
maximum limit is specified in parameter 33-42 Positive Software End Limit.
•
Move the application back from the limit before clearing the error. If power
recovery is enabled in parameter 19-08 Power-Recovery, this can be done
through an error reset and a negative jog (input 54).
•
A motor command has caused the software limit switch to be activated. The
maximum limit is specified in parameter 33-41 Negative Software End Limit.
•
Move the application back from the limit before clearing the error. If power
recovery is enabled in parameter 19-08 Power-Recovery, this can be done
through an error reset and a positive jog (input 53).
•
The motor was not magnetised in a situation where it should have been. The
electromechanical brake is immediately activated in this case regardless of the
settings in parameters 19-12 Hold Delay and 19-06 Error Behaviour.
•
While the motor was holding/driving the load, the frequency converter either
tripped, connection to terminal X57/8 was lost, or the Hand On or Off key on
the LCP was pressed.
•
This error message is given if the motor has moved more than the allowed
number of user units specified in parameter 19-13 Brake Wear Limit while the
electronic brake was activated.
•
The mechanical brake is worn and must be replaced in the near future or the
limit specified in parameter 19-13 Brake Wear Limit is too low.
•
The quick stop input has been activated. As a safety precaution, the electro-
mechanical brake is activated according to the setting in parameter 19-06 Error
Behaviour and the motor is coasted regardless of the setting in parameter
19-09 Automatic Brake Control.
•
Clear the error to resume normal operation.
