CHV100 Series Close Loop Vector Control Inverter
.55.
then start running to its reference frequency based on current speed. This can realize
smooth start of rotating motor with big inertia load when instantaneous power off.
Notice: It only applies on the inverter of 7.5kW and above.

The inverter runs from the Starting frequency. After hold time of starting frequency, the
inverter will accelerate to the setting frequency according to the setting acceleration time.
If the setting frequency is smaller than starting frequency, the inverter stands by. Starting
frequency is not limited by lower frequency limit
Notice: When sensorless vector control or V/F control is active, factory setting of
P1.01 is 1.5HZ, while factory setting is 0 HZ on condition of vector control.

When inverter starts, it performs DC braking according to P1.03 firstly, then start to
accelerate after P1.04.
