Features:
- Provides Precise Variable Speed and Torque Control for Three-Phase AC Motors
- Supports Heavy-Overload and Variable-Torque Industrial Applications
- Integrates Easily into Industrial Automation and Motor Control Systems
The SIEMENS 6SE6440-2UD32-2DA1 Variable Frequency Drive is designed to regulate the speed and torque of three-phase AC motors in demanding industrial environments. Operating on a 380–480 VAC, 47–63 Hz three-phase power supply, the 6SE6440-2UD32-2DA1 delivers 22 kW High Overload (HO) and 30 kW Low Overload (LO) performance. Equipped with sensorless vector control and V/f control, the drive provides smooth acceleration, stable operation, and accurate speed regulation while reducing motor stress and improving overall system efficiency.
The 6SE6440-2UD32-2DA1 serves as a key drive component within industrial automation systems, providing dependable motor control for conveyors, pumps, fans, compressors, mixers, extruders, and other production equipment. The drive supports flexible integration through digital and analog I/O as well as optional communication modules such as PROFIBUS and DeviceNet, enabling seamless connection with PLCs and centralized control systems.
For modernization projects, the 6SE6440-2UD32-2DA1 can be integrated into both existing MICROMASTER installations and upgraded automation systems. Commissioning is supported through Siemens STARTER software and optional BOP/AOP operator panels, allowing efficient parameter configuration and diagnostics.
The 6SE6440-2UD32-2DA1 SIEMENS Variable Frequency Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Material Handling & Conveyors: Utilizes high-grade torque control and precise acceleration/deceleration ramps to smoothly move variable loads without jerking.
- Pumping & Ventilation Systems: Leverages an integrated high-grade PID controller with autotuning for efficient fluid and airflow control, maximizing energy efficiency via programmable quadratic V/f characteristics.
- Lifting & Cranes: Employs an integrated brake chopper (supporting internal dynamics up to 75 kW) and advanced torque handling for safety-critical lifting mechanisms.
- Process Engineering: Suited for mixers, extruders, and agitators that require continuous speed adjustments, slip compensation, and Flux Current Control (FCC) to manage rapid load fluctuations.
- Textiles and Packaging: Features high-speed digital input response times and positioning ramp-down functionality for highly repeatable and synchronized machine cycles.
- Fieldbus Modularity: Out of the box, it interfaces via a basic serial link, but it can be fitted with communication modules for widespread protocols like PROFIBUS DP, DeviceNet, and CANopen.
- Analog Input Resolution: Features two high-resolution 10-bit analog inputs for fine-tuned reference setting or process value feedback.
- Digital I/O Versatility: Offers fast-acting programmable digital inputs and programmable relay/digital outputs for handshaking statuses with master controllers like PLCs.
- PC Connectivity: Can connect directly to a computer via an RS232/RS485 link interface using isolated PC connection kits. This allows configuration via Siemens software suites (such as DriveMonitor or STARTER).
- Control Methodologies: Supports high-quality Vector Control (both open and closed loop), programmable multipoint V/f characteristics, Linear/Quadratic V/f control, and independent torque control modes.
- Operator Interfaces: Can be fitted with a Basic Operator Panel (BOP) or an Advanced Operator Panel (AOP) for direct on-unit programming, parameter cloning, and localized operation.
- Trip-Free Operation: Implements a Fast Current Limit (FCL) feature that automatically controls transient currents to prevent annoying overcurrent trips during sudden load transitions.
- Resiliency Features: Includes kinetic buffering (riding through brief voltage sags using the motor's mechanical energy), flying restart (catching a spinning motor smoothly), and automatic restart capabilities following primary power disruptions.
- Protective Diagnostics: Constantly logs errors and system stats. It tracks vital faults such as Overcurrent (F0001), Overvoltage, and Inverter Overtemperature (F0004) to preserve both the electronics and the connected motor.
