Masso G3 Controllers

Manual Mode Operation

Spindle Systems have a convenient switch on the side of our enclosure which lets you switch between "Manual Mode" and "Automatic Mode". When flipped to manual (up or 1 position) you can hit the run button on the VFD's keypad and turn the dial controlling the motor just like you would a palm router.

Spindle Kits come programmed for immediate use in "Manual Mode". This means you hit the run button and turn the dial to start your spindle motor just like you would a palm router.

Wiring your Spindle to Masso G3 Controller for Automatic Mode Operation

Preparing Controller for Wiring

Your control cable will include a special Spindle Inlet Cable which you can use to wire up your G3 Touch controller. Attaching this inlet cable is relatively easy and we go into detail here: https://support.pwncnc.com/kb/article/336-spindle-inlet-cable-and-masso/

However here are the highlights:

Black => GND

Shield Drain => GND

Red => Pin 1

White => Pin 4 & 6

Yellow => Pin 5

Green => Pin 7

Orange => Tape-off as it is unused.

Use a jumper wire (not provided) to link Pins 4 and 6 together.

The orange wire supplies 10v power and is not required by the Masso G3.

If you have our spindle system, then it's really easy to plug everything up.

If you have our spindle kit, then you'll be digging into the VFD directly to wire it up. Connect it as shown below:

Setting up your VFD for Automatic Mode Operation

This mode is where your CNC controller controls the VFD via a simple PWM variable voltage signal. For Masso G3 this is 0-10v representing 0-24000rpms.

We have pre-programmed your VFD to run in automatic mode when the Manual Override switch is flipped to automatic (down or 0 position). The vfd will monitor the PWM (red wire) and GND (black wire) for how fast the controller is instructing the VFD to spin the spindle motor. You must still hit the "RUN" button on the VFD's keypad to change the vfd from standby/stopped mode (blinking keypad display) to spin/forward mode (solid keypad display).

Running Spindle Kits in Automatic Mode

Our spindle kits do not come with a vfd enclosure and as such you're expected to provide that as well as properly wiring up the high-voltage electrical. If unsure, consult an electrician.

Without our specially designed enclosure, our spindle kits can only run in Manual-Mode OR Automatic-Mode, you are unable to easily switch between them without changing a few program settings within the VFD.

To reprogram your VFD from Manual-Mode operation to Automatic-Mode operation you'll need to change the following settings:

Learn how to navigate your VFD programming here: https://support.pwncnc.com/kb/article/664-how-to-program-your-vfd/

P0.0.03 = 1

P0.0.04 = 3

Your VFD will now monitor the PWM wires to know how fast it should spin the motor when in "Run Mode".

Your Masso G3 is capable of triggering an internal relay which activates the Run/CW/Forward functionality of our VFD via the Yellow and White wires.

When your VFD switches to Run Mode the vfd will change from standby/stopped mode (blinking keypad display) to spin/forward mode (solid keypad display).

Setting up your Masso G3 Controller for Automatic Mode Operation

We're experts in our VFD and spindles, but not experts in your particular CNC Controller. If you have specific questions, we will encourage you to seek advice and guidance from your machine provider.

We have played with Masso G3 controllers before and here are a few notes we've gathered as to how to configure it for controlling a spindle:

From the Masso’s main user interface, go to the “F1 Setup” tab and double-tap “Main Spindle”. Then enter the following information: Encoder: 100, Spindle Control Method: VFD, Maximum RPMs: 24000, Spin UP: 6000, and Spin DOWN: 6000.

Then hit OK and return to the “F2 Program & MDI” screen for testing/validation.

With your manual override button on the VFD down, pressing the blank space next to Spindle CW and typing 6000, then pressing Spindle CW, will turn the Spindle on at 6000 RPM.

You can also go into the MDI dialog your by pressing the MDI button in the lower right and typing M36000. M5 will turn it off.

To test for Automatic control put an RPM in the blank box of the F2 Screen and hit Spindle CW/CCW
