Connector Specifications
Polarity Sensor (Hall Sensor) Output Signal
•
Moving Coil Lead
The figure on the right
shows the relationship
between the Su, Sv, and Sw
polarity sensor (hall sensor)
output signals 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.
Secure the lead from the Moving Coil of
the Linear Servomotor so that it moves
together with the Moving Coil.
