Function
Deceleration stop using deceleration time 1 (C1-02).
Free-run stop
Emergency stop using the fast-stop time (C1-09).
Continue operation (Display “DEV” and continue control.)
Parameter F1-10 sets the PG speed deviation detection level as a percentage of the maximum output
frequency. Parameter F1-11 sets the length of time that the difference between the motor speed and
reference speed must exceed the PG speed deviation detection level in order to generate a PG speed
deviation fault (DEV).
