Siemens 6SL3244-0BB13-1PA1: Control Unit CU240E-2 DP-F for SINAMICS G120, fieldbus PROFIBUS DP.
It plugs onto a G120 Power Module such as the PM240-2 and handles closed-loop control, fieldbus communication and the I/O terminals. It is supplied with DC 24 V from the Power Module or with DC 20 … 29 V from an external supply (per Siemens).
The F in the name marks the fail-safe version: per the data sheet it has 3 (Use of 6 × DI Standard) fail-safe digital inputs for Safety Integrated functions such as Safe Torque Off.
Replacing only the Control Unit is a common, low-cost repair of a G120 drive when the power section is healthy.

- Safety applications with Safe Torque Off
- Repair of a G120 by replacing only the Control Unit
Compatibility and replacement
Fits SINAMICS G120 Power Modules such as the PM240-2. Parameters can be copied from the old Control Unit with a BOP-2/IOP-2 or a memory card if the old unit still works.
What to check first
- Note the motor rating plate data (kW, A, V, Hz, rpm), because they are entered again during commissioning.
- Compare the full order number 6SL3244-0BB13-1PA1 with the rating plate of the old drive; the letters after the power code identify supply, filter and fieldbus version.
- Check the supply voltage, input fuses and motor cable for faults before installing the new drive, so it does not fail for the same reason.
- Save or write down the parameters of the old drive if it still powers up; an operator panel can copy them.
Frequently asked questions
Does it fit the PM240-2?
Yes. The CU240E-2 family plugs onto G120 Power Modules, including the PM240-2 range.
Is an operator panel included?
No. Add a BOP-2 (6SL3255-0AA00-4CA1) or IOP-2 (6SL3255-0AA00-4JA2), or commission it with Startdrive.
Which fieldbus does it have?
PROFIBUS DP, per the Siemens data sheet.
Is it new and original?
Yes. We supply new, original parts in the manufacturer packaging, with a 1-year warranty.
How fast can you deliver, and is there a warranty?
Air shipping usually takes 5 to 7 days once the part is ready, to almost any country. Each part is new and original with a 1-year warranty. Message us on WhatsApp with the order number for a quotation.
Before you order
Compare the complete order number on the old unit with this page, including the suffix: in most ranges the last characters set the coil voltage, current range or version. If the label is worn, send us a photo and we will identify the part.
