6.3 Start/Brake Function Parameter (P2 Group)
P2.00 Start running mode
Range: 0, 1, 2
0
0
：
The inverter starts from start freq.(P2.01) and keeps running at start freq. for duration
defined as start freq. running duration (P2.02).
1
：
The inverter brakes first by DC brake current (P2.03) and brake time (P2.04),and then
starts from start frequency
2
：
The inverter restarts again after speed tracking, which is available for power restored
after momentary power failure and restart after fault reset.

Note:
(1) Start running mode 0: It is suggested to use mode 0 in general applications and
when to drive synchronous motor.
(2) Start running mode 1: It is suitable to small inertia loads which have FWD or REV
running when there is no motor driven. But not suitable to big inertia loads.
(3) Start running mode 2: It is suitable to restart after momentary power failure and
restart during motor free stopping.
