The power cable from the VFD to the spindle motor should beĪ shielded cable and the shield should be grounded to the On/off by using the FWD and REV terminal on its interface and I am going to assume that you are controlling the VFD Is powered, then noise from the VFD is the likely source of the If the commands execute without the VFD powered, but fail if it In the lower half of the window, select Echo commanded RPM unless you haveĪn actual one pulse per revolution signal to use as feedback.

Spindle motor relies on an internal fan and would overheat if run too slow, you Set the value in the Minimum PWM Duty Cycle as needed, for example if your Set the value in the PWM Frequency box to be 50. Select the PWM button near the top of the window.īelow that, select the Pin 14 button as the place to output the PWM. Select the Spindle Config tab at the top of this window. Next use the tabs at the top of the Mach4 screen, go to Configure > Plugins > PMDX-SmartBOB.Ī configuration window for the PMDX-SmartBOB device will open. Now click on the boxes at the bottom of the window for Apply and then OK. Leave the red X in the Active Low column. Use the dropdown in the Output Select column to select Pin 1. Now scroll down the list of signals until you find Spindle Rev in the left column.Ĭhange the red X in the Mapping Enabled column to a green check mark beside Spindle Rev. Use the dropdown in the Output Select column to select Pin 17. Use the dropdown selector in the Device column to select SmartBOBUSB. Scroll down the list of signals until you find Spindle Fwd in the left column.Ĭhange the red X in the Mapping Enabled column to a green check mark beside Spindle Fwd. Pick the Output Signals tab at the top of this new configuration window. Will happen if clicked, not the current state. Your screen, click on it so that it changes to read Enable. If you have a red Disable button in the lower left of When I measure +10V on Gecko, it really says +10V, when I measure 0-10V signal, it always shows 0.48V, which is pretty much 5% duty cycle.Using the tabs at the top of the Mach4 screen, go to Configure > Mach.

Mach3 from some reason does not want to start spindle.įunny is, when I check "average spindle speed" in spindle settings and then punch CWF5, RPM jumps to 24000 and then quickly ramps down to 0. It makes perfect sense for stepperes, not so for spindles.ħ) When I try to punch speed into spindle and do CWF5, I see nothing.

I have no idea, how to map steps, velocity and acceleration on spindle. I was ensured bu many G540 users and Geckodrive support, that it should be ok.Ģ) I have G540 hooked up on VFD, (3 cables: +10V, 0-10V signal, COM)ģ) I have VFD jumpered so it should go always forward (just for now) so I do not need relays for now.Ĥ) I have spindle configured to be driven by PWM 50Hz, min 5%ĥ) I set up pulley with ratio 1:1 and max RPM 24000.Ħ) Spindle motor tuning: here is a first hicup. So far I had no success doing so.ġ) I used "default" G540 XML configuration file which can be downloaded for G540. Ok, I'm trying to get my VFD to be hooked up on the G540, all driven by Mach3.
