Description: 6SL3244-0BB12-1BA1
The Siemens 6SL3244-0BB12-1BA1 is a standard **Control Unit CU240E-2** for the modular **SINAMICS G120** inverter system. It handles the open-loop and closed-loop control functions of the Power Module.
Technical Data
- Protocol: RS485 (USS, Modbus RTU).
- Safety: STO (Safe Torque Off) integrated.
- I/O: 6 Digital Inputs, 3 Digital Outputs, 2 Analog Inputs.
- USB Interface: Yes, for parameterization.
Versatility
The **6SL3244-0BB12-1BA1** is the workhorse of general-purpose drives. It fits on any PM240 / PM240-2 Power Module. The inclusion of the STO safety function makes it suitable for applications requiring basic safety compliance without external safety relays.
Replacement
If replacing a faulty CU, remember to transfer the MMC/SD card or use the PC inverter connection kit to upload the parameter set. The RS485 interface allows easy integration into legacy networks.
