Adjustments Relating to Control
When there is oscillation, rollback, or other control problems, adjust the parameters as specified by the control
method.
shows only the frequently adjusted parameters.
Note:
Torque and speed response for high-resistance and high-slip motors are slow. Adjust the torque and speed response to increase them.
Low impedance (low-slip) motors will hunt and oscillate. Adjust the torque and speed response to increase them.

V/f Control
When you use V/f Control, do not use
C3-01 [Slip Comp Gain]
.

Open Loop Vector Control Method
Do not adjust parameter
C4-01 [Trq Comp Gain]
. Keep this parameter at its default setting.
If you cannot get speed accuracy during regeneration, set
C3-04 = 1 [Slip Comp@Regen = Enable>6 Hz]
. If you
cannot get speed accuracy at high speeds, set
C3-05 = 1 [Vout Limit Selection = Enabled]
.
