Description
1. Product Title
Siemens 6SN1118-0DG23-0AA0 – SIMODRIVE 611-D Single Axis Performance Closed-Loop Control Unit
2. Product Overview
The Siemens 6SN1118-0DG23-0AA0 is a plug-in digital closed-loop control unit belonging to the SIMODRIVE 611-D drive system. Designed for single-axis motion control, 6SN1118-0DG23-0AA0 supports both feed axes and main spindle drives with direct measuring system interfaces. It executes high-performance position, speed and current closed-loop control, receives setpoint commands from SINUMERIK CNC systems, and works cooperatively with matching power modules. This unit accepts Sin/Cos 1 Vpp incremental encoders and EnDat signals, delivering high-resolution position feedback. Comprehensive built-in monitoring and diagnostic functions detect drive faults, supporting stable, precision machining under continuous industrial operating conditions.
