Specification Amperage : 19 amps Brand : Automation Technology Inc. BulletPoint : cnc spindle BulletPoint1 : NOTE:spindle need to be equipped with this vfd to use.Rated frequency of spindle is 400 Hz,If you input 220v/110v voltage at 50hz or 60hz, it will damage the spindle and vfd DOES NOT support external resistor.Fan runs all the time even though the motor isn't (fan functions need to be customized). BulletPoint2 : This VFD can be used for constant torque loads (such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter.This item use Sine wave PWN(SPWM) for the control system.work well with the Mach 3 controller BulletPoint3 : 7 PCS ER20 Collet Set : 1mm,2mm,3.75mm,4mm,5mm,6.35mm,7mm BulletPoint4 : The spindle motor applied to: wood carving/engraving machine, advertisement engraving machine,CNC machine, small sized processing center, high speed centrifuge etc. BulletPoint5 : If there are problems in use after you receive,please don't give us negative or natural feedback,and your return will be a great loss to us.Due to the VFD is a flexibly configurable device, please be sure to contact us and we will give you a satisfactory solution.
