Product features

The Siemens 6SE6440-2AD32-2DA1 is a high-quality frequency converter from the renowned MICROMASTER 440 series, designed for reliable industrial motor control. As a genuine Siemens product, it integrates a built-in Class A filter, making it compliant with industry EMC standards and suitable for various industrial applications. This 22 kW Siemens frequency converter delivers constant torque of 22 kW and squared torque of 30 kW, with a rated output current of 45 A, ensuring stable performance for heavy-duty tasks.

The Siemens 6SE6440-2AD32-2DA1 uses a 3-phase AC power supply from 380V to 480V, with a voltage tolerance of ±10% and frequency range of 47Hz to 63Hz. It has a maximum output voltage of 480V AC (which matches the input voltage) and an output frequency range of 0 to 650Hz, allowing for flexible speed control of AC motors. With a high overload capacity, it can withstand 150% rated current for 60 seconds and 200% rated current for 3 seconds, effectively preserving the motor and converter from harm under peak loads.

This Siemens MICROMASTER 440 inverter (model 6SE6440-2AD32-2DA1) includes practical interface configurations to fulfill industrial control requirements. It features six digital inputs, two analog inputs, two analog outputs, and three relay outputs, all of which can be programmed for specific control. The built-in RS485 interface supports the USS protocol and can link with PROFIBUS, CANopen, and DeviceNet via optional modules, allowing for smooth connectivity to industrial networks.

The Siemens 6SE6440-2AD32-2DA1 has a small design of 520mm × 275mm × 245mm (H×W×D) and weighs around 18kg. It has an IP20 protection grade and may be wall-mounted vertically in indoor industrial applications. It operates consistently at ambient temperatures ranging from -10°C to +50°C (without operation panels) and may be kept at temperatures ranging from -40°C to +70°C, allowing it to adapt to changing working circumstances.

FAQ

Q: What is the Siemens 6SE6440-2AD32-2DA1?

A: The Siemens 6SE6440-2AD32-2DA1 is a model from the well-known MICROMASTER 440 (MM440) series of variable frequency drives (VFDs). It is a 3-phase AC drive with an integrated A-class sine-wave filter and a power output of 30 kW (40 HP) at 400 V. This model is intended for precise and reliable speed control of conventional three-phase asynchronous motors.

Q: What is the main advantage of the built-in A-class filter in this model?

A: The integrated sine-wave filter provides a significant advantage. It eliminates the need to purchase and install an external filter separately, conserving space in the control cabinet, simplifying wiring, and ensuring EMC Directive compliance for conducted emissions from the start. This makes the 6SE6440-2AD32-2DA1 an ideal plug-and-play drive solution for situations that require low electrical noise.

Q: Can the 6SE6440-2AD32-2DA1 communicate with PLC systems?

A: Yes. While it includes typical analog/digital interfaces, its communication capabilities are enhanced with an optional PROFIBUS DP module (e.g., CB15). This enables it to operate as a slave device on a PROFIBUS network, allowing for centralized control, monitoring, and data interchange with master controllers such as Siemens SIMATIC S7-300/400/1500 PLCs.
