Compensation constant of motor 1
0.1－25.0【2.0s】
The motor’s slip changes with the load torque, which results in the variance of motor speed. Through
slip compensation (the inverter will automatically adjust its output frequency according to the load
torque) to reduce the influence.
• In driving status (the actual speed is lower than the
setting speed) and in generating status (the actual
speed is higher than the setting speed), the slip
compensation gain (F09.09) should be increased
gradually.
• The value of auto slip compensation depends on the
motor’s rated slip, consequently make sure the motor’s
rated frequency (F08.03) and rated speed (F08.04) are
set correctly.
Range of slip compensation = Slip compensation limit
(F09.11) × Rated slip.
Rated slip = F08.03 - F08.04 × Np / 60.
• Np is the number of the motor pole pairs.

0: Disabled.
1: Enabled all the time.
2: Disabled in deceleration process.
• The output voltage can be regulated to maintain constant via AVR. Thus, normally the AVR
function should be enabled, especially when the input voltage is higher than the rated voltage.
• In deceleration process, if the F09.14 = 0 or F09.14 = 2, the running current will be a little higher;
while if the F09.14 =1, the motor will decelerate steadily and the current will be smaller.
F09.15 Oscillation-suppression mode of motor 1 0,1

】
0: Oscillation suppression is dependent on the motor’s exciting current component.
1: Oscillation suppression is dependent on the motor’s torque current component.

This function is used to damp oscillation when output current is continually unstable.
• This function helps to keep the motor running smoothly through correctly adjusting the setting of
F09.16.
