Product Description

Lifecycle Status:

The Siemens SIMODRIVE 611-D 6SN1118-0DK21-0AA1 Closed-loop Control Plug-in Unit is a high-performance component of the modular SIMODRIVE 611 digital drive system. It offers superior control for up to two axes, making it ideal for feed and main spindle applications.


This unit is compatible with a variety of motors, including 1FT6, 1FK, 1FE1, 1FW6, 2SP1, 1PH, 1PM, and 1FN series. It supports advanced encoder systems such as incremental encoders with sin/cos 1Vpp signals and absolute value encoders with EnDat protocol, ensuring precise position and speed feedback.

The Siemens 6SN1118-0DK21-0AA1 is a flexible system component that, when paired with a power module, forms a complete drive. It serves as an ideal spare part for maintaining and upgrading existing SIMODRIVE 611 systems, ensuring continued optimal performance and dynamic response in demanding industrial applications like CNC machine tools and robotics. Note that NC software version 6.4.9 or higher is required for compatibility with SINUMERIK 810D/840D.
