Sensor signal: step of actual value oversized.
Description | During active distance control (see [FCT-M3) the encoder values of the sensor or probe system are monitored due to safety reasons to detect errors in the distance measurement. This error message is issued if the encoder value changes by more than the specified limit within a CNC cycle.

For axis-specific distance control, the limit is defined using Description and for 3D distance control using Description.

Response | Class | 7 | Controlled halt of the axis, the control loop is closed.
Solution | Class | 6 | Check the sensor/probe system
Parameter | %1: | Logical axis number [-] or Logical channel number [-]
Logical axis number Axis parameters of the axis affected for axis-specific distance control, logical channel number Logical number of a NC channel (P-CHAN-00400) for 3D distance control.
%2: | Error value [1µm/s or 0.001°/s]
Actual value change of sensor/probe system
%3: | Upper limit value [1µm/s or 0.001°/s]
Permissible limit value Description or Description
%4: | Block number [-]
Block number in the NC program
Error type | -
