When the value of (rotation speed – motor frequency) exceeds Pr.10-07 setting, detection time
exceeds Pr.10-08 or motor frequency exceeds Pr.10-05 setting, it will start to accumulate time.
If detection time exceeds Pr.10-06, the encoder feedback signal error will occur. Refer to
Pr.10-09 encoder stall and slip error treatment.
