Siemens 6SN1118-0DH21-0AA1 Simodrive LT-Module

Siemens 6SN1118-0DH21-0AA1 Simodrive LT-Module is a two-axis, closed-loop plug-in control unit from the SIMODRIVE 611-D family, designed for use with digital drives in industrial automation. The LT-Module Int designation and the 2×15 A specification indicate its role as an LT variant with a 2×15 A current rating, compatible with SIMODRIVE 611-D hardware backplanes for plug-in installation. This module provides two-axis closed-loop servo control for feed and main spindle drives in systems that operate without a direct measuring system, enabling precise, coordinated motion for twin-axis applications. Typical uses include CNC-inspired or machine-tool feed and spindle control where compact, plug-in control is required, and it is intended to be paired with Siemens drive electronics within the SIMODRIVE ecosystem to support synchronized two-axis operation.
