The 6SE6440-2UD32-2DA1 is an industrial-grade three-phase AC frequency inverter. Featuring an unfiltered design and an IP20 protection rating, this drive is developed for controlling various complex industrial motors, delivering precise speed and torque control.
RS485 communication with USS protocol support
22 kW power rating for heavy duty (CT)
30 kW power rating for light duty (VT)
The 6SE6440-2UD32-2DA1 accepts a three-phase 380–480V input at 47–63Hz, delivering a three-phase AC output up to 480V with a 4 kHz carrier frequency. The output frequency ranges from 0 to 650 Hz in V/f control mode.
The 6SE6440-2UD32-2DA1 inverter incorporates an integrated brake chopper, allowing direct connection to a braking resistor for dynamic deceleration tasks. For communication and local control, its front slot interface supports the quick plug-in of a Basic Operator Panel (BOP) or Advanced Operator Panel (AOP), as well as PROFIBUS and DeviceNet modules for automated network integration. Featuring BiCo technology, this unit enables flexible digital input/output mapping to adapt to complex interlocking factory control sequences.

Water & Wastewater Treatment
Controls the operating speed of centrifugal pumps in large booster pump stations, providing variable frequency constant pressure water supply via pressure feedback.
Building Materials & Cement
Drives screw conveyors and belt weigh-feeders in cement clinker production lines to achieve precise raw material proportioning and feeding.
Mining & Mineral Processing
Provides speed control for slurry pumps and flotation cell agitator shafts in ore dressing plants, handling harsh fluid mediums with high concentrations of solid particles.
Metallurgy & Iron & Steel
Used for synchronous speed control of auxiliary roller table motors in steel rolling mills, and for air volume regulation in reheating furnace exhaust systems.
Petrochemical Industry
Drives refinery water injection pumps and process pipeline oil transfer pumps, meeting fluid flow control requirements across different chemical process sections.
Power Generation & Boiler Systems
Controls the variable frequency operation of induced draft and forced draft fans in small-to-medium industrial boilers, adjusting furnace air volume in real time based on load changes.
Keep the operating temperature between -10°C and +40°C for Low Overload (LO) mode, and between -10°C and +50°C for High Overload (HO) mode; storage and transport temperatures must remain between -40°C and +70°C. This unit relies on internal fans for forced-air cooling; sufficient clearance space must be left above and below the drive during installation, vents must never be blocked, and dust should be cleaned regularly.
The 6SE6440-2UD32-2DA1 inverter is rated at 30.00 kW (40.00 hp) with an input current of 59.00 A and an output current of 62.00 A in Low Overload (LO) mode. In this mode, the drive allows 140% output current for 3 seconds, followed by 110% output current for 57 seconds, and then 100% output current for 240 seconds within a 300-second cycle time. This rating is suitable for variable torque loads such as fans and centrifugal pumps.
