Note The motor speed will not be controlled while the PG is disconnected. Set this time as short as
possible in any application where safety cannot be ensured.

Overspeed Settings (F1-03, F1-08, and F1-09)
Overspeed refers to an excessive motor speed. These parameters set the conditions for an overspeed
fault and the stopping method that is used when an overspeed fault occurs; they cannot be changed
during operation.
Parameter F1-03 sets the stopping method that is used when an overspeed fault occurs.

PG Speed Deviation Settings (F1-04, F1-10, and F1-11)
PG speed deviation refers to the difference between the actual motor speed and the reference com-
mand speed. These parameters set the conditions for a PG speed deviation fault and the stopping
method that is used when a PG speed deviation fault occurs; they cannot be changed during operation.
