Name Description
Setting Range [Default]
F09.09
Slip compensation gain of motor 1
0.0 - 300.0 [100.0%]
F09.10
Slip compensation filter time of motor 1
0.01 - 10.00 [0.10s]
F09.11
Slip compensation limit of motor 1
0.0 - 250.0 [200.0%]
The motor slip changes with the load torque, which results in the variance of motor speed. Reduce the
influence through slip compensation.
•
Electric and generating state can increase slip compensation gain (F09.09).
•
Slip compensation limit is fixed value within constant torque. It increases in proportion to output
frequency within constant power.
•
Auto slip compensation depends on rated slip of motor. User should properly set rated frequency
(F08.03) and rated Rpm (F08.04).
Range of slip compensation = actual slip compensation limit × rated slip
F09.12
Motor 1 iron loss
0.000 - 9.999kW
[Depend on model]
F09.12 is used for slip compensation under V/f control. F09.12 has been set according to rated power of
motor. In general, user does not need to set F09.12 but can set if user can get iron loss value from test
report of motor.
F09.14
AVR (automatic voltage regulation) function of motor 1
0 - 2 [1]
F09.14 is valid in V/f control mode only. AVR always act in open loop vector control.
0: Disabled.
1: Enabled all the time.
2: Disabled in Dec 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 Dec process, power regenerates from the load to inverter and bus voltage rise, if F09.14 = 0 or 2, the
running current will be a little higher; while if F09.14 =1, the motor will decelerate steadily and the
current will be smaller.
F09.15
Low frequency oscillation-suppression of motor 1
0 - 200 [50]
F09.16
High frequency oscillation-suppression of motor 1
0 - 200 [20]
This function is used to suppress the existed oscillation when inverter works with motor.
•
If output current changes repeatedly when inverter runs with constant load, user can adjust F09.16 to
depress oscillation to keep running smoothly.
