Setting 8: To increase torque and control speed precisely. (1:1000). This setting is only for
using with permanent magnet motor and others are for induction motor.

Settings
This parameter determinates the PWM carrier frequency of the AC motor drive.

Frequency
From the table, we see that the PWM carrier frequency has a significant influence on the
electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise.

Auto Voltage Regulation (AVR) Function

VF VFPG
mode
Settings
It is used to select the AVR mode. AVR is used to regulate the output voltage to the motor. For
example, if V/f curve is set to AC200V/50Hz and the input voltage is from 200 to 264VAC, the
output voltage won't excess AC200V/50Hz. If the input voltage is from 180 to 200V, the output
voltage to the motor and the input voltage will be in direct proportion.
When setting Pr.00-13 to 1 during ramp to stop and used with auto accel./decel. function, the
acceleration will be smoother and faster.
