Description:
SSO - Safe speed observer speed error. Speed error limit has been violated.
The deviation between the observed rotor flux speed and the speed of the voltage observer is bigger than the allowed speed error limit.
The additional information (Info1) shows the actual absolute speed lag error [m/s * 2^16].
Reaction:
The status S_NotErrENC/S_Status_EncStatus is set to FALSE.
If a safety function is used which needs the SSO, then the module changes into Functional Fail Safe state.
Cause/Remedy:
Check the parameters in the safety application.
Check the mechanical connection between the encoder and the motor.
