Re: Rigid Tapping Setup

It doesn't matter what the exact rpm is. CNC12 uses the encoder to synchronize the Z-axis with the actual rpm as read from the encoder.

Re: Fuji servo drives with acorn.

That sounds like a great addition to the Six family!

Re: Linear Scale with Acorn 4-axis

Yes, it can be done with Acorn. I don't know if it's possible with the Wizard. You may have to edit the parameters directly.

Re: Actualizacion EMCO VCM 300

Which part of the instructions is giving you problems? 1. Set speed on VFD to 1/3 of rated speed 60Hz = 20Hz 2. Set acceleration/deceleration time 1.5 seconds (01-12, 01-13) 3. Set 11-00 = 2 , Inertia auto-tuning 4. View 11-01 during tuning 5. Press forward and reverse until the inertia is stable. T...

Re: Auto Spindle

Is your spindle encoder showing any errors on the PID screen?

Re: Auto Spindle

The 100% key commands 100% of programmed (via an Snnnn) command, or 50% of maximum speed if running in manual spindle mode.

Re: Fuji servo drives with acorn.

You might want to recheck the Encoder expansion board documents. I believe it supports differential encoder INPUTS for reading encoders. I do not believe it supports differential quadrature OUTPUTS to control a servo motor drive.

Re: Fuji servo drives with acorn.

Marc spotted in the manual where these drives can be configured for step and direction input. Theoretically, all that you would need to do to get them to work with Acorn, would be to create a single-ended to differential converter for the inputs. There are TTL logic chips available that can do this.

Re: Inaccuracy issue

Just because the DRO returns to zero, does not mean you are not losing steps. Unless you have connected the drive alarm signals to Acorn (and configured the inputs accordingly) , the Acorn has no way of knowing if your drives and motors may have missed steps. You need to set up an indicator on the a...
