Variable Frequency Drive 220V 3KW 4HP Inverter For CNC Spindle Motor Speed Control With 3 Phase Output 0 To 400Hz And 1 Or 3 Phase Input RS485 Cable Included For Water Cooled And Air Cooled Spindles

3KW 220V CNC Spindle Drive with 0-400Hz Output
✔️ 1/3 phase input, RS-485, 0-400Hz output, single unit

This 3KW variable frequency drive (VFD) controls CNC spindle speed, taking 1 or 3 phase 220V input and delivering 3 phase 220V output up to 0-400Hz. It supports RS-485 for controller integration and includes a cable for quick setup with water cooled or air cooled spindles.

✅ 3KW 220V VFD drives CNC spindle speed across 0-400Hz for precise control
✅ 1 or 3 phase input with 3 phase 220V output and RS-485 control
✅ 5 digit display shows frequency, current, voltage, rpm and temperature
✅ Programmable V/F curve with up to 150% torque and 10% startup torque
✅ AVR, DC brake, deceleration and soft stop features
✅ 6 input and 5 output terminals for control and status signaling
✅ Overload, over/under voltage, anti stall, and thermal protection
✅ Vertical mounting recommended for best cooling; operating -10 to 40 C

This drive is designed for tight integration with CNC controllers and is suitable for both water cooled and air cooled spindles in industrial and hobbyist setups.
