Controlling Spindle using a VFD
WARNING: Please exercise extreme care when setting up your VFD and Spindle. These are not
toys and can lead to injury or death if not handled correctly. If you have any doubt contact a
suitably qualified electrical technician to assist with your installation. VFD's are complex devices
that MUST be installed by a certified person and treated with respect not only because they
contain High voltages but also because incorrect configuration of a VFD can destroy both the VFD
and the Spindle.
There are various VFD connection examples (provided as a reference only) within the documentation, please
note that it is not practical to provide examples of every VFD model and please see the one that suits your
VFD model.
MASSO provides a 0-10v signal to control spindle speed (RPM).
Two open collector optical switches for forward (clockwise) and reverse (counter-clockwise) signals.

HINT: The biggest issue that users have following the VFD install video is they ignore the first
instruction of the video to follow all of the steps. Some steps may seem unnecessary like setting
the VFD to work manually but this is one of the most important. If you cannot get it to work
manually with simple on/off switches and a potentiometer it will not work when connected to
MASSO no matter what you do. As tempting as it is to connect everything at once, please do it
step at a time and test as you go. Doing this can take a few extra minutes but can save you hours
or days of work figuring out what is wrong.
HINT: The Spindle will not turn unless you issue a speed for it to run at. eg S10000 and a M3 or
