1326 motors are described in the 1326 Servomotor Product Data
(publication 1326A-2.9). The 1326 series of motors operate at either
460V ac or 380V ac. Connection of these motors is made directly to the
Axis Module.
Each 1326 motor is equipped with a resolver required for motor
commutation. This resolver can also be used for positioning feedback,
or an external A quad B encoder can be used for positioning. Resolvers
are connected to the feedback board found in the system module.
