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
indicated by the arrow in the
dimensional drawings of the
Moving Coil.
