It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of its channel.

Besides this, it activates the external emergency output.

The possible causes are:

1. The difference between the position value of the linear encoder connected to the CNC (second feedback) and that of the motor encoder (first feedback) is greater than the value of a.m.p. FBACKDIF (P100).
2. Feedback combination being active, the counting direction of the first and second feedback is not the same or the difference between the first and second feedback is greater than 838 mm.

The solutions for each case are the following:

1. Check that the counting direction of both feedbacks is the same. Disable the feature that causes the error by setting a.m.p. FBACKDIF (P100) = 0.
2. Check that the counting direction of both feedbacks is the same.
