Connector Specifications
Polarity Sensor (Hall Sensor) Output Signal
•
Servomotor Connector
The figure on the right shows
the relationship between the
Su, Sv, and Sw polarity sen-
sor (hall sensor) output sig-
nals and the inverse power of
each motor phase Vu, Vv, and
Vw when the Moving Coil
moves in the direction indi-
cated by the arrow in the
dimensional drawings of the
Moving Coil.
