This is the inverter supplied with the MILL TURN and TURNADO machines from serial # 17111 on. It has the capacity to run up to 2 HP 3 phase motors. It requires 220 volt single phase input ( like water heater or clothes dryer) and it outputs 220 volt 3 phase power to run the machine spindle motors. The inverter comes with a detachable programmable key pad and remote ribbon cable so the keypad control can be mounted in a convenient place on the machine housing. The key pad and ribbon are available as spare parts under the part #'s ST36 K and ST36 R. The keypad offers a variety of functions to change the coding of the inverter for a variety of applications and has a speed control knob to allow spindle speed to be adjusted with a simple turn of the knob. The inverter can also be programmed to operate through the Mach 3 software to control spindle speeds, forward, reverse and stop-start functions, as well as CSS ( Constant Surface Speed ). The inverter varies the motor by changing the frequency ( Hz ) while maintaining full voltage for excellent power at low RPM. The Hz settings can be set from 0 to 600 Hz for a variety of motor applications, however for the MILL TURN and TURNADO motors, the maximum setting is 120 Hz. The inverter has a built in cooling fan which is augmented by the extra machine fan to keep temperatures in the proper range. It also has voltage and temperature overload protection built in.
PLEASE NOTE- For early MILL TURN and PATRIOT VFD owners this unit will replace the NOWFOREVER unit and we can supply the correct wiring diagram for your machine.
