Cause : Motor data identification activated comes when the motor data identification routine is activated or the motor data identification routine is carried out at the next power-on command.

  1. If rotating measurement is selected (see p1900, p1960), it will not be possible to save the parameter assignment.
  2. Once motor data identification has been completed or de-activated, the option to save the parameter assignment will be made available again. See also: p1910 (Motor data identification selection).

The alarm automatically disappears after the motor data identification routine has been successfully completed or for the setting p1900 = 0.
