Siemens 6SN1118-00J23-0AA1 Simodrive Control Board

Siemens 6SN1118-00J23-0AA1 SIMODRIVE 611 digital control board is a one-axis, closed-loop plug-in control unit for SIMODRIVE 611 digital drive systems. It implements SIN/COS feedback with a 1 Vpp direct measuring system, enabling precise servo positioning and speed regulation for motors in CNC machines and other automation equipment. As a 611-D module, it serves as a plug-in performance control unit for digital drives that manage both feed and main spindle drives using direct measuring system voltage signals. This board belongs to the SIMODRIVE 611 family and is compatible with NC software up to version 6.4.9, reflecting its role within older Siemens control architectures. Related revision variants in the same family—such as 6SN1118-0DG23-0AA1 and 6SN1118-0DJ23-0AA1—illustrate the usual revision-based differences while preserving core single-axis digital control capabilities. Typical applications include single-axis servo control in machine tools where SIN/COS feedback and direct voltage signaling are required for precise motion control. Availability notes from Siemens Industry Mall indicate this module is no longer listed as active stock, with a successor identified for related platforms (for example 810D/840D systems): 6SN1118-0DJ23-0AA0.
