valid mode selection
Define the valid state selection for the multi-function output terminal.
0: Positive logic, the digital output terminal and the corresponding common terminal are connected to
the active state, and the disconnection is in the invalid state.
1: Inverse logic, the digital output terminal and the corresponding common terminal are connected to
an inactive state, and the disconnection is in an active state.

P6 Start and stop control

P6-00 Start model
0：Direct start if the DC braking time is 0, the inverter will start running at the start frequency. If the
DC braking time is not 0, the DC braking is performed first, and then the starting frequency is started.
Suitable for small inertia loads.
1: Speed tracking restart the inverter first judges the speed and direction of the motor, and then starts
with the tracked motor frequency, and implements a smooth and non-impact start for the rotating motor.
Instantaneous power failure restart for large inertia loads. In order to ensure the performance of the speed
tracking restart, it is necessary to accurately set the parameters of the motor P1 group.
2: Asynchronous machine pre-excitation start Used to establish the magnetic field before the motor
runs. Pre-excitation current and pre-excitation time are described in function code P6-05 and P6-06. If the
pre-excitation time is set to 0, the inverter cancels the pre-excitation process and starts from the start
frequency. If the pre-excitation time is not 0, the pre-excitation is restarted first, which can improve the
dynamic response performance of the motor.
Rotational speed tracking

mode
In order to better complete the speed tracking process, select the way the inverter tracks the motor
speed:
0: Track down from the frequency at power failure. This method is usually used.
1: Tracking starts from 0 frequency, and is used when the power failure time is long and then
restarted.
2: Track down from the Maximum frequency, generally used for generating loads.
