Manual tool change only when spindle STOPPED

[ezzupturbo]

Can we get an output that will let us do manual tool changes with power drawbar only when spindle off. If we could have it in the relay outputs that would be great, Don't know how many times i have almost stood on my foot pedal while mill is running

can you please explain the requirements a bit more, what exactly are we trying to do with the tool change logic, a video would be helpful.

I have a pnumatic drawbar on my mill using tormach tooling. When I stand on my foot pedal it releases tooling. I want some relay so it won't allow me to release tool without spindle being stopped.

It sounds to me like you need an interlock between spindle and pneumatic valve, depending on how your spindle is controlled and operates. Do you have a vfd? How long for your spindle to slow to a stop? Can you give a drawing of how it's wired and brand of vfd? Also how the foot pedal circuit works.

Hi guy

Yes I have vfd with braking resistor so it's pretty quick to stop.

Electric foot pedal to relay that activates solinoids to press down on drawbar.

Its just a delta vfd-e

Like you said some sort of interlock either when spindle stopped or spindle is at tool change location. Or I remove the foot pedal and have a button on the head.

Or I put a relay on z home proxy and set my tool change position to z home and use that as the interlock.

I have it..

I'll run it off my mist solinoid.

Then my coolant mist is running I will have it open circuit for my tool change relay. So it can only be activated when cooland is off.

I was actually thinking about tying into the vfd circuit but hey the coolant output will certainly do to. That's what I call thinking outside the box. By the way nice wiring job there, I like to see that

@ezzupturbo the safest and best option is to use an output from your spindle that then controls a relay to interlock the foot pedal. On most VFD's you can setup an output to go HIGH/LOW if the motor is running.

Yes this is correct the delta vfd-e has 2 relay outputs. One is being used for alarm to the masso and I can change the parameter on the other to activate at zero speed. This will be perfect for what I plan to use it for.

Thanks again

So after a bit of mucking about its all sorted.

Using M01 output on the delta vfd I was able to stop power to my power drawbar solinoid until the spindle had a stop command.

Now I can change back to a foot pedal safely without risking damaging any tooling.

nice work @ezzupturbo

@ezzupturbo Hello, I like your controller, I'm new to dyn4 and I would like to connect it to Masso. For me, the problem is connecting Driver to Masso. I hope you can help me. I watched some of your pictures you have done with your control box it is perfect but if you could help me wiring the driver and controller. My email is mustafic.idriz@gmail.com. Best regards.

Hay mate I literally wired exactly as per diagram.

I also added an alarm out to the masso.

@idriz have you set the setting in the DYN4 software by connecting the drive to the PC and using their setup software? the drive might have a different mode programmed.

Yea good point.

You will need to set to pulse/dir in the command input mode as it could possibly be set to rs232

No, I didn't connect it with my pc. I'm planning to connect it directly like in the diagram to masso if it is possible? So im looking at what you guys think, you are more experienced than me. thank you

You are required to connect to pc laptop to change parameters. Not required to be connected constantly

Can you give me more detailed on how to connect, step by step what I need to do first than what?

Jump on YouTube and watch all the setup videos on dmm dyn4 drives.

Its as simple as downloading the software plugging usb into drive, selecting serial port then choosing pulse/dir from the menu. It is an easy drive if not the easiest drive to setup.
