PwnCNC's VFD Upgrade Kit

⚙️ PwnCNC’s VFD Upgrade Kit

Modernize Your CNC. Boost Performance. Simplify Control.

PwnCNC’s VFD Upgrade Kit is designed for makers ready to take the next step in spindle control and reliability. Whether you’re replacing an aging VFD or upgrading your spindle setup, this kit delivers everything you need for a clean, efficient, and powerful system—built with the same trusted PwnCNC quality and attention to detail found across our spindle lineup.

This kit includes a pre-programmed Variable Frequency Drive (VFD) with the correct power and spindle cabling for your setup—so you can spend more time cutting and less time wiring. Simply choose your voltage (110V or 220V) and Spindle Motor connector type (H17 or H20), and you’ll receive a ready-to-install system compatible with most spindle motors on the market.

✅ What’s Included

• PwnCNC Pre-Programmed VFD (110V or 220V)
  Fully configured for clockwise/counterclockwise rotation, PWM/Modbus control, and quiet fan mode.

• Power Cable
  Pre-terminated cable (NEMA 5-15P for 110V or L6-20P for 220V) — plug in and go.

• Spindle Cable (H17 or H20)
  Shielded, pre-crimped, and grounded for clean signal transmission and reduced electrical interference.

⚙️ Key Benefits

• Drop-in upgrade for most hobby and semi-pro Spindle setups

• Pre-programmed for fast, trouble-free installation

• Works with a wide range of 1.5kW–2.2kW spindle motors

• Cleaner power delivery and quieter operation than older units

• Fully supported by PwnCNC’s documentation and customer service

💬 Notes

This kit does not include a spindle motor — it is intended as a VFD and cabling upgrade for users who already have or plan to supply their own spindle.
Installation is straightforward: mount the VFD, connect the spindle and power cables, and follow instructions in the KB.

For best results, pair with a PwnCNC spindle motor or Spindle Mount System for optimal performance and full support.

⚠️ Important Compatibility Notes

• Compatible with most 1.5kW–2.2kW spindles

• Choose H17 or H20 connector based on your spindle model

• Confirm your spindle’s voltage and amperage before ordering
