Spindles

Will a particular spindle work with MASSO?

  • MASSO provides a 0~10v, CW and CCW signals to control spindle speed (RPM).
  • Two open-collector optical switches for forward (clockwise) and reverse (counter-clockwise) signals.
  • If your VFD conforms to this format then MASSO will work with your spindle.

Spindle drive options

  • VFD - This would be a standard spindle drive setup with 0-10v drive signal.
  • PWM - Designed to be used with H-Bridge drives 4Khz to 65Khz with 0-100% duty cycle
  • Step and Direction - For use with servo drives using a 500hz to 25Khz step pulse rate

How do I connect my Spindle?

It is not possible to provide wiring diagrams for every VFD or provide advice on how to configure specific VFD’s. Please consult your VFD manual and VFD supplier for configuration settings.

Our documentation provides examples of some common VFDs and we have produced a step-by-step video explaining how to connect a VFD to MASSO.

Pulleys and Gearboxes?

MASSO does not support the use of Pulleys or Gearbox drives making only one selected gear ratio correct.
You will need to manually calculate the required RPM when using a gear different from the one that you set MASSO spindle up to use.
For Example If you have a 2:1 reduction between one gear and another you would need to request 1000 RPM to get 500 RPM in the 2nd gear.
 

Note: With Lathe when threading the spindle encoder is used to determining the Z axis speed when threading. This means that the if you are using a Gearbox or pulley threading will not be affected and the thread will still be the correct pitch no matter the requested spindle speed. This also means that lathes without spindle speed control will also cut the correct thread pitch no matter the requested spindle speed.
