Hi, if i set p491 to

1 (1: Enc fault results in encoderless oper. and oper. continues)

or

5: Enc fault results in encoderless op, operation continues, alarm

drive should continues operation and still rotating  a motor (go to encoderless operation) without stop if data from encoder will be lost.

When drive go back to operation with encoder? When signal from encoder back and be ok, or when i stop motor and start again?

Drive is S120 Chasis inverter 250kW with CU-320-2 DP, for encoder use SMC30 module. Drive work on vector with encoder operation
