Siemens 6SL3244-0BA21-1PA0 SINAMICS G120 CU240S DP F Control Unit
Legacy PROFIBUS control unit with integrated safety functionality for SINAMICS G120 drive systems.
Core Capabilities
Functions
Controls the connected SINAMICS G120 Power Module and motor functions.
Supports PROFIBUS DP communication for drive integration.
Supports safety-related drive applications through the F-version architecture.
Stores and manages drive parameters and commissioning data within the G120 control architecture.
System Setup
Installation
Mount the Control Unit on a mechanically and electrically compatible SINAMICS G120 Power Module.
Connect PROFIBUS and any required safety communication according to Siemens commissioning instructions.
Commission safety functions separately and verify the safety configuration before operation.
Use only Power Modules and firmware combinations supported by Siemens documentation for this CU generation.
Product Status
Lifecycle
This is a legacy CU240S generation. Siemens support material still documents it for installed-base systems, while newer CU240x-2 generations are used for current G120 platforms. Confirm replacement compatibility before changing to a later Control Unit.
