Siemens 6SN11180NK010AA0 Resolver Module

The Siemens 6SN11180NK010AA0 Resolver Module, an integral component of the SIMODRIVE 611 U HR series, offers advanced closed-loop control capabilities for precision industrial applications. Specifically designed as a 2-axes closed-loop control plug-in resolver, this module plays a crucial role in providing accurate position and speed feedback for motors in CNC (Computer Numerical Control) systems.

Key Resolver Specifications:

The resolver, serving as a motor encoder, operates with a pin. It has a flexible configuration with the number of pole pairs equal to 1 or the pole-pair count of the motor, allowing seamless integration with various motor types.

The resolver excitation is a noteworthy feature, as the control unit produces a voltage with 4.3 VRMS at 9.6 kHz. The nominal input voltage of the controller is sin/cos 2.0 VRMS, and the transmission coefficient of the resolver is approximately 0.46 at 9.6 kHz, often described with a 1:2 transformation ratio in datasheets.

The maximum excitation current is 28 mARMS, corresponding to the minimum magnitude of 154 Ω of the complex input impedance of the resolver. This ensures stable and reliable resolver operation under varying conditions.

Modules Included in the Scope of Supply:

The SIMODRIVE 611 U HR series offers various configurations, making it adaptable to different control requirements. The included modules range from high-performance 2-axis or 1-axis control units to high-standard 2-axis control units, with options for direct measuring systems. Additional variants include HLA/ANA for highly dynamic hydraulic axes or universal dynamic analog interfaces.

Motor Encoder Options:

The motors equipped with the Siemens 6SN11180NK010AA0 Resolver Module support various encoder systems for sensing rotor position and speed. The recommended encoder signals for fault-free operation include track signals A+, A–, B+, B–, C+, C–, D+, and D–.

Depending on requirements, different encoder types are utilized, such as sin/cos 1 Vpp or EnDat encoders, SSI encoders (specific to certain SIMODRIVE 611 variants), resolvers (exclusive to SIMODRIVE 611 universal), and TTL encoders (compatible with SIMODRIVE 611 universal and induction motors).

In conclusion, the Siemens 6SN11180NK010AA0 Resolver Module is a versatile and high-performance component within the SIMODRIVE 611 U HR series, providing precision control for industrial applications. Its flexible resolver configuration, comprehensive module options, and support for various encoder systems make it a reliable choice for demanding CNC systems and other motion control applications.
