Re: Anilam to Oak Conversion Project

Do you feel you have the basic electrical/electronic background to carry out such a conversion? Have you done a conversion before? Use good wiring practices. I would use matched motors/drives that have been proven to work with Oak. You will need the signal cables as well. Nicer to buy drives that Ce...

Re: Automatic DOOR

There is a door safety interlock as a usable input. Why don't you use that? Are you trying to automate the door opening and closing? If so, why? I'm trying to understand why a pneumatic door, it is a safety issue in of itself. Please clarify the point of the automatic door. Then we can better unders...

Re: Need help with spindle motor recommendations

The easiest and best method, 3 phase motor with a good VFD Add a spindle encoder belted at 1:1 with a timing belt to the spindle itself with a timing belt. You are asking us to guess at what you have. Pictures, details about the current motor and current drive would help us better provide useful sug...

Re: is there any way to use a servo for 4th axis on acorn?

Ive got some big DC brushless servos leftover from another project. The servo drive can be put in velocity mode or torque mode. It seems like the common way to control these is using analog 0-10V. The manual for the driver is attached. I would like to make a 4th axis for my mill using one of these ...

Re: Displayed Spindle Speed is Incorrect

Where did the KBSI-240D Come from?
IS it a known good drive?

The KBSI240D's job is to provide mains isolation. Not just supply 0-5VDC.

Re: Displayed Spindle Speed is Incorrect

Please, ALWAYS post a fresh report when asking for help. It has all your machine parameters in it.

Have you run the Basic Acorn Spindle bench test?
This might help:


Need to make sure Acorn spindle analog output is functioning correctly first.

Re: Hardinge HC CNC Turret Lathe

Make and model of the VFD? The reason I ask for make and model of the VFD, is so we can see if it is capable of running on single phase. Some will, some may not. It would eliminate the need of a phase converter all together. Worst case power the control on 220vac single phase and power the VFD from...
