Product Description
Overview
The 9100-00049-03 from Emerson is a high-performance resolver interface module designed for integration with Unidrive SP, Commander SK, and Digitax ST drives. It serves as a dedicated signal evaluation and protection module, enabling precise position and speed feedback from resolver-equipped motors. Its robust design ensures reliable operation in demanding industrial environments where temperature, vibration, or electrical noise could compromise standard encoder systems.
Key Features and Functions
-
Provides high-resolution digital feedback from standard 2-phase resolvers (Sine/Cosine).
-
Converts analog resolver signals into precise digital data for closed-loop vector control.
-
Equipped with advanced diagnostics including excitation fault detection and loss-of-signal monitoring.
-
Plug-and-play installation into compatible Emerson drive option slots.
-
Ensures stable operation under high-speed and variable load conditions.
