Set the starting mode of motor
0: Starting with starting frequency:
Firstly operating a period with setup start frequency and start frequency retention time, then doing
acceleration/deceleration operation according to acceleration/deceleration time setup slope, refer to
P01.01.
2: DC braking and start:
According to current value and retention time, keep DC current for a while, then start according to 0
mode.
3: Speed tracking start:
Inverter checked the motor RPM firstly, then start according to detect motor RPM.

Start frequency is the initial frequency when inverter starting, as below diagram showed, start
frequency retention time is the run time under start frequency. Start frequency generally set 1Hz~2Hz.
In low power application, by setting start frequency can quickly build slip, which is helpful in quickly
start motor. For big power or heavy load application, properly extend start frequency retention time,
can pre-excitation motor and reduce start current and boost start torque. If motor is rotating when start,
can make motor speed getting low then acceleration later.

The DC braking before starting is the DC current before motor rotating output for in a period, P01.03
set input DC current value, 100.0% is relative to inverter rate current. P01.04 set the time of DC input.
By injecting DC current to realize the effect of electromagnetic brake on motor and pre-excitation. For
big power and heavy load application, via pre-excitation, start torque get bigger, impact current get
smaller.
