3 HP Spindle / VFD Systems

  • Input power: single-phase 200-240VAC, 50/60Hz
  • Current draw (approx.): 8A at peak load (minimum 10A circuit recommended)

These spindles come pre-wired with an L6-30 plug, which mates with an L6-30 receptacle. This can be field retrofitted to a different 240VAC plug if necessary. Consult a qualified electrician for assistance with any changes to the stock power cable.

4 HP Spindle / VFD Systems

  • Input power: single-phase 200-240VAC, 50/60Hz
  • Current draw (approx.): 11A at peak load (minimum 15A circuit recommended)

These spindles come pre-wired with an L6-30 plug, which mates with an L6-30 receptacle. This can be field retrofitted to a different 240VAC plug if necessary. Consult a qualified electrician for assistance with any changes to the stock power cable.

8.7 HP Spindle / VFD Systems

  • Input power: 3-phase 208VAC2 or single-phase 200-240VAC1, 50/60Hz
  • Current draw (approx.): 27A at peak load (minimum 30A circuit recommended)

The system comes pre-wired with an L21-30 plug, which mates to an L21-30 receptacle. A 3-phase to single-phase plug adapter is included for use with an L6-30 receptacle.

AV70S Spindle / VFD Systems

Power Requirements

  • Spindle Controller Input Power
    • Input power: 3-phase 208VAC2 or single-phase 200-240VAC, 50/60Hz
    • Current draw (approx.): 28A at peak load (minimum 30A circuit recommended)
    • The system comes pre-wired with an L21-30 plug, which mates to an L21-30 receptacle. A 3-phase to single-phase plug adapter is included for use with an L6-30 receptacle.
  • Spindle 24VDC Power Adapter
    • 100-240VAC input
    • NEMA 1-15P plug for standard North American wall outlets

Compressed Air Requirements

  • AV70S Spindle
    • Supply Pressure: 95-115 PSI (105 PSI recommended)
    • Supply Pressure Connection: 1/4" Male Industrial Quick Disconnect
    • Minimum Air Flow: 2 SCFM @ 100 PSI3
    • Filtration: 40µm minimum

1 Operating the 8.7 HP Spindle / VFD system on single-phase power will reduce the spindle's peak power to 6.4 HP.

2 Three-phase input power must be a three-wire or four-wire Wye system. Three-phase 380-480VAC power must be stepped down to three-phase 200-240VAC (typically 208VAC).

3 The drawbar consumes 2-3 SCFM intermittently. Case pressure consumes approximately 2-3 SCFM continuously while the spindle is running. Case pressure is required if any coolant is used and is highly recommended when cutting abrasive materials (MDF, composites, foam). A minimum compressor and tank size recommendation is 2.4 SCFM @ 90 PSI, 125 PSI max pressure, 3 gallon tank. Increasing flow, max pressure, or tank size will reduce the duty cycle.
