Distance control active but encoder delivers no valid actual positions.
Description | An axis with active distance control (see [FCT-M3]) is to be moved although one of the sensors does not deliver valid positions. Value 2 of the error message indicates which of the two distance measuring sensors triggered the fault. Possible output values:

1 - Actual position of the axis

2 – Configured velocity of the axis

3 - Additive actual position value of the axis

4 - Second additive actual position of the axis

Response | Class | 7 | Controlled halt of the axis, the control loop is closed.
Solution | Class | 6 | Remedy the cause for sensor fault.
Parameter | %1: | Logical axis number [-]
Logical axis number P-AXIS-00016 of concerned axis
%2: | Current value[-]
Indication for erroneous sensor
Error type | -
