Chapter 6 Description of Function Codes
Group P1: Start-stop control
0: Direct start
When the start DC braking time is not set to 0, the DC braking is performed first before starti-
ng. It is suitable for occasions where small inertia loads may reverse during startup.
1: Restart after speed tracking
The inverter first judges the speed and direction of the motor, and then starts at the frequency
corresponding to the tracked motor speed, and implements a smooth and shock-free start for
the rotating motor, which is suitable for instantaneous power failure of large inertial loads.
start up.
2: The asynchronous motor is pre-excited to start
Which is used to establish a magnetic field before the operation of the asynchronous motor to
reduce the current impact during rapid start.

In order to complete the speed tracking process in the shortest time, select the way that the
inverter tracks the motor speed:
0: Track down from the frequency at the time of power failure, this method is usually selected;
1: Start tracking from the target frequency, and use it when the power failure time is longer
and restart;
2: Start tracking from the current speed, generally used for power generation loads.

In the speed tracking restart mode, select the current and speed of the speed tracking. The lar -
ger the parameter, the faster the tracking speed. But too large may cause unreliable tracking.
