Control Unit | 6SL3244-0BB13-1FA0 Siemens

Product Introduction

The SINAMICS CU240E-2 PN-F (Article No. 6SL3244-0BB13-1FA0) is a high-performance control unit from Siemens. It pairs seamlessly with Power Modules to build a versatile variable-speed drive system. This unit focuses on communication flexibility and safety integration.

Specifically, it supports PROFINET and EtherNet/IP protocols. Consequently, it fits easily into most modern automation networks. Moreover, its compact design saves valuable cabinet space.

Electrical Data and Power Supply

This control unit operates via the Power Module using DC 24 V. Alternatively, you can supply it with an external power source ranging from DC 20 to 29 V. Its maximum power consumption is 0.50 A, while power loss stays at 5.50 W. Therefore, it remains energy-efficient during continuous operation.

Furthermore, the unit includes robust overvoltage protection. It complies with SEMI F47 standards, ensuring stable performance during voltage dips.

Communication Capabilities

The CU240E-2 PN-F excels in industrial networking. It features built-in PROFINET and EtherNet/IP communication ports. Thus, you can easily integrate it with PLCs, HMIs, and SCADA systems.

Additionally, the unit supports cyclic and acyclic data exchange. This enables real-time monitoring and parameter adjustments. You can also use standard Ethernet cables for easy wiring.

Digital and Analog Inputs/Outputs

This control unit offers a rich set of I/O options. First, it provides 6 standard digital inputs. Their switching levels are:

• 0 → 1: 11 V

• 1 → 0: 5 V

For safety applications, it includes 1 fail-safe digital input. However, this function uses 2 standard DI channels internally. Therefore, you retain flexibility while meeting safety requirements.

Next, the unit features 2 digital outputs as relay changers. These outputs handle switching loads up to standard relay ratings.

For analog signals, it provides 2 analog/digital inputs (differential type). These inputs accept current or voltage signals. Meanwhile, 2 analog outputs (non-isolated) deliver 0–20 mA or 0–10 V signals for external devices.

Closed-Loop Control Techniques

The CU240E-2 PN-F supports multiple control methods. V/f linear, square-law, and parameterizable modes are available for basic applications. Additionally, V/f with flux current control (FCC) improves motor stability at low speeds.

For energy savings, use V/f ECO linear or square-law modes. These reduce power consumption in partial-load conditions.

More advanced users can leverage sensorless vector control. This technique delivers high torque accuracy without an encoder. Furthermore, encoderless torque control enables precise tension or winding applications. Note that vector control with a sensor and torque control with an encoder are not supported.

Ambient Conditions and Durability

This unit operates reliably in harsh environments. Its ambient temperature range is:

• Operation: -10 to 55 °C (14 to 131 °F)

• Storage: -40 to 70 °C (-40 to 158 °F)

Relative humidity can reach up to 95% during operation. Therefore, it suits humid industrial settings. The IP20 / UL open type degree of protection requires installation in a control cabinet.

Mechanical Data and Dimensions

The control unit has a compact footprint. Its dimensions are:

• Width: 73.0 mm (2.87 in)

• Height: 199.0 mm (7.83 in)

• Depth: 46.0 mm (1.81 in)

The net weight is only 0.49 kg (1.08 lb). This lightweight design simplifies mounting on DIN rails.

Connection Specifications

For signal cables, the unit accepts conductors from 0.05 to 1.50 mm² (AWG 28 to AWG 16). Use shielded cables for analog signals to reduce noise. All terminals are spring-type for quick and secure wiring.

Standards and Compliance

The CU240E-2 PN-F meets global standards. It carries CE, UL, cUL, RCM, and SEMI F47 markings. Additionally, it complies with the Low-voltage Directive 2014/35/EC. Therefore, you can use it in Europe, North America, and Australia without additional certifications.

FAQ

1. Can this unit work with a 110 V AC supply?
No, it requires DC 24 V from the Power Module or an external DC supply (20–29 V).

2. Does it support Profibus communication?
No, this model supports PROFINET and EtherNet/IP only. For Profibus, consider the CU240E-2 DP variant.

3. How many fail-safe inputs does it have?
It has 1 fail-safe digital input, which internally uses 2 standard DI channels.

4. Can I use this control unit without a Power Module?
No, it needs a compatible SINAMICS G120 Power Module to drive the motor.

5. What are the shipping options?
We ship via FedEx, UPS, or DHL. Delivery time depends on your location and selected service.
