Fixed stop not detected.
Description | The fixed stop was not detected during the Move to fixed stop function [FCT-M8]. Possible causes:

1. Approach block path too short.
2. The fixed stop moved.
3. Position lag limit too large (see P-AXIS-00712)
4. Too many wait cycles (see P-AXIS-00714)
5. Torque limit too small; the axis did not move
6. Torque limit too large; the fixed stop slipped
7. Monitoring area in the approach block was too small, see START and END tokens in [FCT-M8//Programming]

Response | Class | 4 | Controlled halt of the axis, the control loop is closed.
Solution | Class | 6 | Check the fixed stop and the parameterisation.
Parameter | %1: | Logical axis number [-]
Logical axis number P-AXIS-00016 of concerned axis
%2: | Current value [0.1%]
Start the fixed stop monitoring function in the approach block
%3 | Current value [0.1%]
End the fixed stop monitoring function in the approach block
Error type | 1, Error message from NC program.
