MD280/MD280N User Manual Parameter Description
- 123 -
1) In the applications where the inertia is very low, the over
excitation gain is set to 0, while in the applications where the inertia is
high, it needs to improve the over excitation gain properly.
2) In the applications where there is brake resistor, the over
excitation gain must be set to 0.

It needs to be set according to the motor parameters. If this value is set
wrongly, it may affect the motor control performance. If it is uncertain,
please contact the motor manufacturer.
Oscillation
suppression gain
Factory default
value
Model dependent
F1-17
Setup range 0 to100
When the motor has no oscillation, please select this gain as 0. Only when
the motor has obvious oscillation and does not run normally can the gain
be properly increased. The bigger the gain is, the better oscillation
suppression result will be.
The gain shall be set as small as possible under the condition that the
oscillation is suppressed effectively so as to avoid high influences on the
V/F operation.
