F09.14 AVR (automatic voltage regulation) function of motor 1 0
2
1
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
0: Oscillation suppression is dependent on the motor’s exciting current component.
1: Oscillation suppression is dependent on the motor’s torque current component.
F09.16 Oscillation-suppression coefficient of motor 1 0
200
50
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.
