Control Techniques STDU04 Resolver Feedback Module

Description:

The Control Techniques SM-Resolver Issue 02.00 STDU04 Resolver Feedback Module is used in AC drive systems to provide resolver-based speed and position feedback for closed-loop motor control applications. Commonly installed in Uni-drive SP variable frequency drives, servo systems, machine tools, printing presses, and industrial automation equipment operating in harsh environments requiring rugged feedback devices. Maintenance teams and system integrators use this part for drive repairs, resolver feedback upgrades, motion control retrofits, and OEM machine maintenance.

Applications:

The SM-Resolver Issue 02.00 STDU04 module is commonly used to interface resolvers with Control Techniques Uni-drive SP drives for closed-loop speed and position control. Typical applications for the STDU04 include CNC machinery, steel processing equipment, printing machines, paper converting systems, cranes, hoists, and heavy industrial equipment operating in high-temperature, high-vibration, or contaminated environments where resolver feedback offers improved reliability compared to optical encoders. The module also provides simulated incremental encoder outputs for integration with external control systems.
