Siemens 6SN1118-0BJ11-0AA0 Servo Drive Module

Siemens 6SN1118-0BJ11-0AA0 is a SIMODRIVE 611 closed‑loop servo drive control unit designed for resolver control on a single axis and featuring an analog setpoint interface. This plug‑in module provides the analog command input and resolver feedback that drive a servo motor within a SIMODRIVE 611 installation, enabling precise position and speed control of one axis. As part of the SIMODRIVE 611 family, it is intended to work with the corresponding power modules in the same system to implement single‑axis servo control. The 6SN1118‑0BJ11‑0AA0 variant is described in Siemens literature as a one‑axis analog interface resolver regulation device, delivering a standard analog interface for setting targets and receiving resolver feedback for closed‑loop operation. Typical applications include precision positioning and motion control tasks where resolver feedback is used for one axis, such as feed drives or indexing stages in automated processes. This module is used within legacy SIMODRIVE installations to control servo motors with high precision via a resolver input, forming a key component of the SIMODRIVE 611 ecosystem.
