Note 1. A: Advanced
---: Not applicable.
Note 2. These parameters cannot be changed during operation.
Note 3. A gear ratio of 1 (F1-12 = F1-13 = 1) will be used if either of these parameters is set to 0.
H
Selecting Integral Operation During Acceleration/Deceleration (F1-07)
When “V/f control with PG feedback” is used, integral control during acceleration and deceleration can
be enabled or disabled with F1-07. This parameter cannot be changed during operation.
Set F1-07 to “1” (integral control enabled) if you want to keep the motor speed as close to the frequency
reference as possible during acceleration and deceleration. Set F1-07 to “0” (integral control disabled) if
you want to prevent the occurrence overshooting/undershooting.
