Winding Selection Motor Standard Connections Diagram
As shown in the following diagram, this system requires winding selection signals in addition to speed refer-
ence signals such as the FWD and REV signals.
A special magnetic contactor that can be driven directly from the SERVOPACK with transfer contacts is also
used to switch the winding.
