5.2 Start/Stop Control (Group P1)
P1.00 Start mode
Range: 0~2【0】
0: Start directly
1: Brake First and then start at start frequency
2: Speed tracking restart (It is only effective for the motor of 35R5GB/37R5PB or
above)
Note:
Start directly: Speeds up from zero-speed and accelerate to the preset frequency
within the preset Acc time.
Brake first and then start: Inverter adds some DC injection braking power to load
first, and then startup. As shown in Fig. 5-1-1. Starting mode 1 is suitable for small
inertia load which is running forward or reverse while the inverter is in stop state,
such as fan load. DC injection braking parameters refer to P1.03 and P1.04.

Speed tracking restart: Search and catch the motor’s running direction and speed,
and then start at the caught speed , running to the reference frequency within the
Acc/Dec time, realize smooth start of motor, as shown in Fig. 5-1-2. This mode is
suitable for the motor with big inertial load.
