[Hd130] 0 to 50(%)
The frequency at which the sensorless vector
control is started.
Set the ratio to the base frequency [Hd104].
8
No-Load current
for Sync.M-SLV,
1st-motor
[Hd131] 0 to 100(%)
Set the ratio of the no-load current to the rated
current during the sensorless vector control.

00
01 Initial position estimation is enabled.
IMPE 0V wait num-
ber for Sync.M,
1st-motor
[Hd133] 0 to 255
This is a stand-by adjustment value to stabilize
the reference value for the initial position esti-
mation detection.
10
IMPE detect wait
number for
Sync.M, 1st-motor
[Hd134] 0 to 255
This is an adjustment value to stabilize the cur-
rent rise of the initial position estimation opera-
tion.
10
IMPE detect num-
ber for Sync.M,
1st-motor
[Hd135] 0 to 255
This is a detection-operation adjustment value
of the initial position estimation operation.
30
IMPE voltage gain
for Sync.M,
1st-motor
[Hd136] 0 to 200(%)
This is a output-voltage adjustment gain of the
initial position estimation operation.
100
IMPE Mg-pole
