SINAMICS G120 CU240E‑2 DP‑F – Product Introduction 6SL3244‑0BB13‑1PA1

Product Introduction

The SINAMICS G120 CU240E‑2 DP‑F (Article 6SL3244‑0BB13‑1PA1) is a feature‑packed control unit for modular drive systems. It works exclusively with SINAMICS G120 Power Modules. This unit prioritizes safe motion monitoring and fieldbus connectivity.

Specifically, it supports PROFIBUS DP for deterministic cyclic communication. Therefore, it integrates smoothly into classic automation architectures. Meanwhile, its onboard Safety Integrated functions reduce the need for external safety relays.

Electrical and Power Supply Details

This control unit draws its power directly from the connected Power Module. The nominal supply voltage is DC 24 V. No external power supply is required for basic operation.

Its maximum power consumption stays below 0.5 A. Consequently, heat dissipation remains low, which enhances long‑term reliability. Additionally, the unit includes internal short‑circuit and overload protection.

Communication – PROFIBUS DP

The CU240E‑2 DP‑F features a PROFIBUS DP interface with 9‑pin D‑sub connectivity. It supports baud rates up to 12 Mbit/s. Thus, it handles real‑time process data exchange with PLCs and HMIs.

Furthermore, you can configure the station address via DIP switches or software. The unit also supports PROFIdrive profile V4.0. This ensures interoperability with third‑party controllers.

Digital and Analog I/O Configuration

This control unit offers a versatile I/O mix. 6 digital inputs accept standard 24 V signals. Additionally, 3 digital outputs provide direct switching capability for small actuators.

For analog signals, you get 2 analog inputs (differential, 0–20 mA or 0–10 V). Meanwhile, 2 analog outputs (non‑isolated) drive external meters or valves.

A special feature is the PTC/KTY interface. This allows direct connection of motor temperature sensors. Hence, you can implement thermal overload protection without extra modules.

Safety Integrated Functions

The F‑type designation means this unit includes extended safety features. Beyond the basic STO (Safe Torque Off), it supports:

• SS1 (Safe Stop 1) – controlled deceleration with monitoring

• SLS (Safe Limited Speed) – speed restriction for maintenance modes

• SSM (Safe Speed Monitor) – zero‑speed detection

• SDI (Safe Direction) – prevents reverse rotation

These functions meet SIL 2 and PL d standards. Therefore, you can reduce machine footprint and wiring complexity. Moreover, safety parameters are stored in a write‑protected memory area.

Additional Interfaces – USB and SD/MMC

For convenience, the unit includes a USB port and an SD/MMC card slot. Use the USB connection for direct parameter upload/download via STARTER or Startdrive. The SD/MMC slot enables firmware updates and cloning of drive parameters. This simplifies fleet management across multiple machines.

Ambient Conditions and Mechanical Data

This model operates within 0 to +50 °C (ambient) without the Power Module. Storage temperature ranges from ‑40 to +70 °C. Relative humidity must stay below 95% (non‑condensing).

Its IP20 / UL open type protection requires installation inside a control cabinet. Dimensions are:

• Width: 73 mm

• Height: 199 mm

• Depth: 46 mm

Net weight is 0.49 kg. The unit snaps onto a standard 35 mm DIN rail.

Standards, Compliance, and Environmental Data

The CU240E‑2 DP‑F carries CE, UL, cUL, and RCM markings. It complies with RoHS (since 01.07.2006) and the WEEE take‑back obligation.

According to REACH, it contains Lead (CAS 7439‑92‑1) above 0.1% (w/w) – mainly in solder joints. The SCIP number is 34cc936d‑a6f5‑4bd1‑9d3d‑957ee6e64bbf.

Export control classifications: AL = N, ECCN = N – no special restrictions apply. Country of origin is Great Britain.

Installation and Commissioning Tips

Follow these practical steps for a smooth startup:

1. Mount the unit on a DIN rail. Ensure at least 50 mm clearance above and below for airflow.

2. Connect the Power Module via the built‑in DC link interface. Use shielded motor cables for EMC compliance.

3. Wire PROFIBUS DP with a standard 9‑pin D‑sub connector. Terminate the bus at both ends.

4. Set the station address using the DIP switches on the front panel.

5. Load the safety configuration via the USB port or SD card. Then verify all parameters before enabling the drive.

Always power off the system before connecting or disconnecting any cables. Use a 2 A slow‑blow fuse for the 24 V supply.

FAQ

1. Can this unit run without a Power Module?
No. It requires a compatible SINAMICS G120 Power Module to supply the DC link and drive the motor.

2. Does it support PROFINET?
No. This model is PROFIBUS DP‑only. For PROFINET, choose the CU240E‑2 PN‑F (6SL3244‑0BB13‑1FA0).

3. What safety levels do the integrated functions achieve?
They meet SIL 2 (IEC 61508) and PL d (ISO 13849‑1) for most applications.

4. How do I update the firmware?
Copy the firmware file to a FAT‑formatted SD/MMC card, insert it, and power up the unit – the update starts automatically.

5. What shipping carriers do you use?
We ship worldwide via FedEx, UPS, or DHL. Delivery times vary by destination.
