Settings

Setting
0 Deceleration to stop using deceleration time 1 (C1-02).
1 Coast to stop
2 Emergency stop using the emergency-stop time (C1-09).
3 Continue operation (To protect the motor and machinery, this is not normally set.)

Overspeed Settings: F1-03, F1-8, F1-09

Overspeed refers to an excessive motor speed.
D
Set the conditions (level and time) for detecting overspeed and the stopping method that is used when
D
an overspeed is detected.

F1-08 and F1-09 Settings
D
Constant F1-08 sets the overspeed detection level as a percentage of the maximum output frequency.
Constant F1-09 sets the length of time in seconds that the motor speed must exceed the overspeed
detection level in order to generate an overspeed fault.

PG Speed Deviation Settings: F1-04, F1-10, F1-11

After an agreement of the actual motor speed and the reference speed has been detected (depending
D
on the setting in F1−04), the differrence between the actual motor speed ( caluculated from the PG feed-
back value) and the frequency reference must exceed the PG speed deviation detection level set in
F1−10 and the allowable time set in F1−11 to detect a PG speed deviation(DEV.)
These constants set the conditions (level and time) for detecting PG speed deviation and the stopping
D
method that is used when a PG speed deviation is detected.
