⚙️ Technical Description – Siemens 6SN1117

The Siemens 6SN1117 control modules are part of the SIMODRIVE 611 family, a modular platform designed for axis and spindle control in CNC machines.

They perform several critical functions:

• axis and spindle control management

• high-speed digital communication

• integrated diagnostics

• synchronization with power modules

• interface with SINUMERIK 810D/840D CNC units

Main Technical Features

• Family: SIMODRIVE 611

• Function: digital axis/spindle control

• Bus interface: Siemens Drive-Cliq / proprietary digital bus

• Diagnostics: status LEDs, error messages, internal monitoring

• Compatibility: SINUMERIK 810D, 840D, power modules 6SN1123 / 6SN1145

• Mounting: plug-in installation in SIMODRIVE rack

• Protection: overcurrent control, over-temperature protection, insulation monitoring

These modules stand out for their exceptional operational stability, essential for continuous 24/7 industrial production.

🏭 Typical Applications – Siemens 6SN1117

The 6SN1117 modules are widely used in:

• CNC machine tools

• 3–5 axis machining centers

• automatic lathes

• high-precision milling machines

• grinding machines

• automated assembly lines

• special machinery for automotive, medical, and aerospace sectors

Thanks to their modular architecture, they can be adapted to both simple and highly complex configurations.

⛔ Obsolescence and Production Status

The 6SN1117 series is officially discontinued by Siemens.
This makes availability on the market increasingly limited and makes it essential to rely on certified partners capable of:

• sourcing original modules

• regenerating them with components compliant with Siemens standards

• ensuring compatibility and electrical safety

E-Repair is one of the very few laboratories in Europe able to service this product line with certified procedures.
