Will a particular spindle work with MASSO?

Yes, MASSO can control a wide range of spindles provided the spindle drive (VFD or drive) supports standard control signals.

MASSO provides:

0–10V analogue output for spindle speed (RPM)
CW and CCW control signals
Two open-collector optical outputs for forward (clockwise) and reverse (counter-clockwise) operation

If your VFD or spindle drive supports this control format, it will work with MASSO.

Spindle drive options

MASSO supports the following spindle control methods:

VFD (0–10V):
Standard spindle control using a 0–10V speed signal
PWM:
Designed for H-bridge drives, operating from 4 kHz to 65 kHz with 0–100% duty cycle
STEP/PULSE and DIRECTION:
For servo-based spindle drives using a 500 Hz to 25 kHz pulse rate

How do I connect my Spindle?

It is not possible to provide wiring diagrams or configuration instructions for every VFD.

You should:

Refer to your VFD manual
Consult your VFD supplier for configuration settings

MASSO documentation includes example wiring diagrams for common VFDs, along with a step-by-step video showing how to connect a VFD to MASSO.

Pulleys and gearboxes

No, MASSO does not support automatic pulley or gearbox ratio switching.

Only one gear ratio can be configured in MASSO. If you change to a different pulley or gearbox ratio, spindle speed must be calculated manually.

Example:
If the configured ratio is 1:1 and you switch to a 2:1 reduction, you must command 1000 RPM to achieve 500 RPM at the spindle.
