Parameter Description

AVR selection
1:Valid all the time
1
2: Invalid during
deceleration
AVR means output voltage auto regulation.WhenAVR is invalid, output voltage will change
according to the change of input voltage (or DC bus voltage); WhenAVR is valid,output voltage
will remain constant within output capacity.
Note: When the motor is decelerating to stop, the inverter would decelerate to stop in a
shorter time and not to be over-voltage if automatic voltage stabilization AVR function is closed.

0: Direct start: start from the starting frequency.
1: DC braking first and then start: First perform DC braking (pay attention to set up
parametersF0.17 and F0.18 ), and then start and run the motor at the start frequency. It is suitable
for small inertia loading which can cause reverse rotation at starting.

frequency
Setting proper starting frequency can increase the starting torque.Within the hold time of the
starting frequency (F0.16), the inverter output frequency is the starting frequency, and then,from
the starting frequency, running to the target frequency. If the target frequency (frequency
command) is less than the starting frequency, inverter does not operate and is at stand-by state.
The starting frequency value is not restricted by the lower limit frequency.
During FWD/REV switching, the starting frequency is inactive.
