Chapter 6 Parameter Description
-63-
“Disabled only at the time of deceleration” can
greatly reduce the possibility of over voltage
fault alarm. When there is brake resistor or it
has not need for fast deceleration, select AVR
“Always Enabled".

Setting this parameter can compensate the
slip in the V/F control mode due to load and
reduce the change of rotation speed of the
motor following the load change. In general,
100% corresponds to the rated slip of the
motor with rated load. Slip coefficient
adjustment can refer to the following
principles: When the load is rated load and the
slip compensation coefficient is set to 100%,
the rotation speed of the motor in the inverter
is close to the reference speed.

Setup range

Select “0” for this gain when the motor has no
oscillation. Only when the motor has obvious
oscillation and cannot run normally can this
gain be properly increased. The bigger the
gain is, the better oscillation suppression
result will be. The method of selecting this
gain is to select the smallest one on the
premise that there is effective oscillation
suppression measure, so as to ease the
negative effect on the VF operation.
