Product Description: 6SE6440-2UD17-5AA1

The 6SE6440-2UD17-5AA1 is a MICROMASTER 440 series VFD providing robust speed and torque control for three-phase AC motors up to 7.5 kW (10 HP). It accepts a 380–480 V AC input, features sensor-less vector control and an integrated braking chopper. Delivered without an internal EMC filter, it allows users to add a site-specific filter. Housed in an IP20 panel-mount enclosure, it’s ideal for demanding applications such as pumps, fans, mixers, and conveyors.

Key Features

• Sensor-less Vector Control: Fast dynamic response and precise speed regulation
• Integrated Braking Chopper: Ready for external braking resistor to handle rapid deceleration
• Advanced I/O: 6 programmable digital inputs; 2 analog inputs (0–10 V / 0–20 mA); 2 analog outputs; 2 relay outputs
• Communication Options: Optional PROFIBUS-DP, CANopen, DeviceNet, Ethernet/IP, USS/Modbus RTU
• Built-In PID: Closed-loop control of pressure, flow, or temperature without external PLC
• Easy Commissioning: Parameter macros and Basic Operator Panel (BOP) or STARTER PC software
