Product Description
It manages motor control, I/O and communication for motors from 0.37 kW to 250 kW using V/f and sensorless vector control. The unit provides an RS485 interface with USS and Modbus RTU, plus USB and SD/MMC slots, making it a compact, low-cost control core for standard drive tasks. The Siemens 6SL3244-0BB12-1BA1 is the CU240B-2 control unit for the modular SINAMICS G120 drive system, pairing with a PM240-2 power module to form a complete frequency converter.
Basic Product Information
- RS485 with USS and Modbus RTU communication
- Integrated PTC/KTY/Thermoclick motor-protection interface
- USB and SD/MMC slots for commissioning and cloning
- V/f and sensorless vector (FCC) closed-loop control
- CU240B-2 control unit for modular SINAMICS G120 drives
Technical Specifications
Version & Model Difference
The code 0BB12 identifies the CU240B-2 (Basic) control unit; the CU240E-2 (code 0BE2x) adds more I/O and Safety Integrated STO. This 6SL3244-0BB12-1BA1 is not the E-type and does not include STO by default. It replaces the earlier 6SL3244-0BB12-1BA0 and requires a PM240-2 power module to operate.
Application Scenarios
- Conveyor and material-transport speed control via USS/Modbus
- Pump and fan variable-speed drives for energy savings
- Simple machine-axis control using V/f or sensorless vector
- Retrofit of standard motors in discrete and process plants

Frequently Asked Questions
Does the 6SL3244-0BB12-1BA1 include Safety Integrated STO?
No. This is the CU240B-2 (Basic) unit; STO is part of the CU240E-2 variant. Safety functions are not included by default on this B-type unit.
Which power module does it need?
It must be paired with a SINAMICS PM240-2 power module; the CU alone cannot drive a motor.
What communication protocols are supported?
The built-in RS485 interface supports USS and Modbus RTU; fieldbus options are added via separate modules.
What control methods does it offer?
It supports V/f (linear, square-law, FCC) and sensorless vector control for standard asynchronous motors.
