Restart mode selection
10-08(P.150) is set by 3 bits. The meaning of each bit is as follows:
10-08
(P.150)
=
0
：
No frequency search
1
：

2
：

0
：

1
：

2
：

0
：
No detection of rotation
1
：
The detection of rotation
2
：
00-15(P.78)=0,The direction of rotation
00-15(P.78)=1,2, No direction of rotation
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.
3. The direction detection bit of 10-08(P.150) is only valid for direct frequency search.
4. This function is only valid in V/F control mode (00-21(P.300)=0).
Restart function
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
))”.
