
10-08(P.150) is set by 2 bits. The meaning of each bit is as follows:
10-08
（
P.150
）
=
0
：No frequency search.
1：Reserved
2：Decrease voltage
mode
0
：Power on once.
1：Start each time.
2：Only instantaneous
stop and restart

During motor operation, when instantaneous power interruption occur inverter will stop output immediately. If
10-09(P.57)=99999, inverter will not restart automatically after power is restored; If 10-09(P.57)=0.1~30, when
power is restored, inverter will automatically restart the motor after idling for a period of time (10-09(P.57) value).

When restarting the motor automatically, output frequency is target frequency, but output voltage is zero and then
slowly rises to the proper voltage value. This voltage rise time is called “Restart rising time (10-10(P.58))”.

Note:1. 10-08(P.150) must also be set if need instant restart function.
2. If 10-08(P.150) is not 0, in default inverter do linear acceleration and deceleration.
