Lenze-AC Tech recently released the resolver-based Model 941 PositionServo Drive. The resolver is designed to measure the position of the motor shaft within a revolution, while an incremental encoder can only know the relative position of the shaft. Recommended for applications requiring tight positioning control, the Model 941 PositionServo has an integrated resolver with a scalable emulated encoder output. The output scales the resolution back into the controller, providing fifteen options of positioning resolution. You can also choose your own level of control with the PositionServo drive’s capability of controlling basic torque and velocity applications up through fully programmable coordinated motion.
