Product Description
The module features an analog +/-10 V regulation interface for setpoint integration and is designed for mounting in a SIMODRIVE 611 rack with bus connection to the power modules. It is compatible with SINUMERIK 810D and 840D CNC systems and works with 611 power modules such as the 6SN1121, 6SN1122 and 6SN1145 series. Siemens has ended original production of the SIMODRIVE 611 closed-loop family, and the module is in spare-parts service status; the recommended migration path for new applications is the SINAMICS S120 platform. The Siemens 6SN1118-0BK11-0AA0 is a closed-loop control unit from the SIMODRIVE 611 range, providing closed-loop position and speed control for two independent or synchronized axes using resolver feedback.
Basic Product Information
- Resolver feedback for continuous motor position and speed monitoring
- Analog +/-10 V regulation interface for setpoint integration
- SIMODRIVE 611 rack mounting with bus connection to power modules
- Compatible with SINUMERIK 810D / 840D CNC systems
- Closed-loop position and speed control for two independent or synchronized axes
Technical Specifications
Version & Model Difference
The 6SN1118-0BK11-0AA0 is the main listed code of the 6SN1118-0BK closed-loop family. Service documentation notes that variants with -0AA1 or -0AB0 suffixes have different firmware behavior and slightly different pin assignments, so the exact order number on the front nameplate must be verified before ordering spares. Enhanced revisions 6SN1118-0BL11-0AA0 and 6SN1118-0BN11-0AA0 improve analog circuit reliability and EMI resistance.
