1: DC braking first and then start: First perform DC braking (pay attention to set up
parameters P1.03 and P1.04), 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.
2: Rotating speed tracking and then start: the inverter first calculates motor rotating speed
and direction, and then start running to its set frequency from current speed, performing a
smooth no-shock start to moving motor. This mode is applicable to momentary power-down
start when the inertia loading is big.

Setting proper starting frequency can increase the starting torque. Within the hold time of
the starting frequency (P1.02), 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.

When it is being started, the inverter first performs DC braking according to the set
prior-to-starting DC braking current, and after the set prior-to-starting DC braking time is
passed then begins to perform acceleration. If the set DC braking time is 0, DC braking is
invalid.
The bigger the DC braking current, the greater the braking force. The prior-to-starting DC
braking current is the percentage of the rated inverter current.

0: Linear mode
The output frequency is linearly increasing or decreasing. The Acceleration and
Deceleration time varies based on the set Acceleration and Deceleration time. CHV series
inverter provides 4 kinds of specific Acceleration and Deceleration time, which can be selected
