Motor Control Parameters
S1A53838 09/2011 75
F418 [Frequency loop gain]
1 to 150 40
Parameters F418 and [Freq. loop stability] (F419) reduce the speed of the drive’s response to a change in speed command.
The factory setting of these two parameters assumes that the inertia of the load is three times as large as that of the motor shaft.
Adjust these two parameters if the factory setting is not appropriate for the application.
Note: It is possible for the drive’s output frequency to exceed its upper limit (parameter [Max frequency] (FH)) if the acceleration
parameter (ACC or F507) is set to its minimum value.
Increasing the setting of parameter F418 reduces the drive’s response time to changes in the speed reference.
F419 [Freq. loop stability]
Frequency loop stability 1 to 100 20
Increasing the setting of parameter F419 further reduces the drive’s response to changes in the speed reference.
