Detailed Function Description
45
2: Disabled during
deceleration
AVR ( Auto Voltage Regulation) function ensure the output voltage of inverter stable no
matter how the DC bus voltage changes. During deceleration, if AVR function is disabled,
the deceleration time will be short but the current will be big. If AVR function is enabled all
the time, the deceleration time will be long but the current will be small.

0: Start directly: Start the motor at the starting frequency determined by P1.01.
1: DC braking and start: Inverter will output DC current firstly and then start the motor at
the starting frequency. Please refer to description of P1.03 and P1.04. It is suitable for the
motor which have small inertia load and may reverse rotation when start.

z Set proper starting frequency can increase the starting torque.
z If the reference frequency is less than starting frequency, inverter will be at
stand-by status. The indicator of RUN/TUNE lights on, inverter has no output.
z The starting frequency could be less than the lower frequency limit (P0.06).
z P1.01 and P1.02 take no effect during FWD/REV switching.
