Main encoder can not be changed via list update.
Description | An attempt was made to change the main encoder signal (P-AXIS-00823) using an axis list update. This is not possible. The controller must be restarted to change the main encoder signal.
Response | Class | 7 | Controlled halt of the axis, the control loop is closed. The axis goes to error state. The main encoder signal is not adopted.
Solution | Class | 6 | Perform a reset. A change to the main encoder signal (P-AXIS-00823) requires a controller restart.
Parameter | %1: | Logical axis number [-]
Logical axis number (P-AXIS-00016) of drive affected
%2: | Error value [-]
New parameterised value for P-AXIS-00823
%3: | Corrected value [-]
Previous value of the main encoder signal (P-AXIS-00823)
Error type | 11, Error message from position controller.
