Re: Actualizacion EMCO VCM 300

In the manual you will need to refer to settings PR 06-01 to 06-05. Also PR 07-00 to PR 07-04. Search "braking", "brake" and "decel" in the manual. PR 01-12 and 01-13 set the accel and decel times. I use 0.35s but my motor is smaller. 3s is a good starting point, then g...

Re: Actualizacion EMCO VCM 300

You need to enable the active braking. Otherwise it defaults to internal braking. Putting a DC multimeter across the resistor wires during a braking cycle will tell you if it is dumping into the resistor. Use a meter with 1000V DC rating. Install it where you dont need to be holding it in place. Be ...

Re: Actualizacion EMCO VCM 300

The braking time does not need to be excessive. You will be making your own tool change macro. You will be limited in your braking time anyway by motor efficiency, max drive current and resistor heating. I would start at three seconds, then decrease from there if you are not exceeding any ratings. Y...

Re: Actualizacion EMCO VCM 300

I just saw "it has an output configuration of 230V at 272HZ, 7.5KW for the spindle motor. spindle" so assumed 230V.

Either way, just choose the resistor that the manual says for the appropriate configuration and it will be all good.

Re: Actualizacion EMCO VCM 300

The table in the manual gives suggestions for resistance values for nominal and fast deceleration. The actual deceleration speed that is achievable depends on the rotating mass of your motor, spindle etc. Generally CNC machines have very low spindle inertia compared to say driving a huge fan or flyw...

Re: Actualizacion EMCO VCM 300

Can you tell me the error it is generating? It may be over volts on deceleration. If that is the case then a resistor is required. The delya drive can handle a certain amount of load but after that needs a resistor to dump the deceleration energy into. I used a large resistor on mine but probably di...

It's been a long time since I had to choose a PLC program but from memory they are all available inside the CNC12 installer zip.

Re: Actualizacion EMCO VCM 300

Ok, your call on that one. But he will require all the inputs wired and a list of the wiring locations.

Something tells me that one of the centroid examples is already set up to do a binary code tool changer.

Re: Actualizacion EMCO VCM 300

Thanks for sharing the video. I still don't know much about how that mechanically works and what inputs/outputs are involved. Looks to me that whatever you are doing with those buttons needs to be done by the controller. So a good place to start would be to wire them to the controller and write some...

Re: CNC12 5.08 Upgrade Issues

Attached is a new report. I checked Windows zoom level. It is on 150%. I set it back to 100% and the G code display came right. But everything else in Windows is too small to see or press with my fat fingers! So, I would like to run Windows at 150%. This is a full touchscreen only setup, no mouse or...
