Description:
SSO - Safe speed observer speed error. Speed error limit ("SSO - Speed tolerance safe speed") has been violated.
The deviation between the observed rotor flux speed and the measured rotor flux speed is bigger than the allowed speed error limit ("SSO - Speed tolerance safe speed").
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.
