Pre-excitation start
0: Direct start
If DC braking time is set to 0, the inverter will start from the start frequency.
If DC braking time is set to nonzero value, DC braking will be performed firstly, then the inverter starts from
the start frequency. It is suitable for the application that the motor maybe running during starting with small
inertia load.
1: Speed tracking and restart
Inverter detects the rotation speed and direction of motor, and then starts to run at the detected speed and
direction. This can realize smooth start of running motor with big inertia load when instantaneous power-off.
To ensure the performance of speed tracking restart, please set motor parameters accurately. (Group P1)
2: pre-excitation start
It is only valid for asynchronous motor, used to establish magnetic field before motor running. For
pre-excitation current, pre-excitation time, please refer to P6-05, P6-06 instruction.
If pre-excitation time is set to 0, the inverter will cancel the pre-excitation process, start from the starting
frequency. Or the inverter will make the pre-excitation, then start, which can improve the motor dynamic
response performance.

Setting range
0
Begin from stop frequency
1
Begin from zero speed
2
Begin from maximum frequency
To complete the speed tracking process in the shortest time, select the suitable mode of inverter tracking
motor speed:
0: To track from the frequency when stop, normally it adopts this mode.
1: To track from zero-frequency, suitable for the applications which are restarted after a long time
power-off.
2: To track from maximum frequency and suitable for the general power generating loads.
P6-02
Speed tracking speed
Factory default
20
Setting range
1 ~ 100
It is used to select the speed tracking speed when speed tracking and restart.
The bigger this parameter is, the faster the tracking speed is. But too big value may result in unreliable
tracking.
