Distance control turned on with sensor source 'SECOND_ENCODER', but no second encoder configured.
Description | Distance control was activated with the sensor source “SECOND_ENCODER“.

- Axis-specific distance control
  The sensor signal must be transferred by a second encoder for this sensor source. The second encoder was not configured
- 3D distance control
  it is not allowed to activate 3D distance control using the sensor source “SECOND_ENCODER“.

Response | Class | 7 | Controlled halt of the axis, the control loop is closed.
Solution | Class | 6 | Check and configure a second encoder or change the sensor source.
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: | Block number [-]
Block number in the NC program
%3: | Current value [-]
Current sensor source
Error type | -
