Defines the output logic of the output terminal HDO, relay 1, and relay 2.
0: Positive logic, digital output terminal and corresponding common terminal are
connected to active state and are disconnected to invalid state;
1: Anti-logic, digital output terminal and the corresponding common terminal connected
to an invalid state, open to a valid state.


0:direct start
If the DC braking time is set to 0, the drive will start from the start frequency.
If the DC braking time is not 0, the DC braking will start and then start from the starting
frequency. For small inertia loads, the motor may have a rotating occasion at start-up.

1:speed tracking restart
The inverter first to determine the speed and direction of the motor, and then to track the
motor frequency to start, the rotation of the motor to implement smooth and no impact
start. For a large inertia load instantaneous power failure to restart. In order to ensure the
performance of speed tracking and restart, it is necessary to set the parameters of motor
P1 group accurately.

2: asynchronous machine pre-excitation start
It is only valid for asynchronous motors and is used to establish a magnetic field before
the motor is running.
Pre-excitation current, pre-excitation time See function code P6-05, P6-06 Description.
If the pre-excitation time is set to 0, the inverter will cancel the pre-excitation process and
start from the start frequency. Pre-excitation time is not 0, then the pre-excitation and then
restart, can improve the motor dynamic response performance.
If the DC braking time is set to 0, the drive will start from the start frequency.
If the DC braking time is not 0, the DC braking will start and then start from the starting
frequency. For small inertia loads, the motor may have a rotating occasion at start-up.
