Boxford 190vmc upgrade

Hello,

Delayed (sorry) reply to Steve, and anyone else who is interested. I have the manual for the Lenze drive if it's of any use. I also have some other documentation including a wiring diagram and user manual. If anyone is interested I'll put some stuff on my FTP site so it can be downloaded.

You should be able to run the drive with a 10K pot and a switch to see if it works. The terminals have 10V control and ground available but as stated on previous post this lot could be (NB - manual implies it is) at mains potential so be careful!

I have got nowhere with mine, lots of work has come in, enough to last til Christmas. I'll get there one day. :-)

Hi David/Jazz,

Spent some time today connecting the 107 board to the Lenze control board. It looks like the Lenze only allows for 0 - 5v input from the 107, thus i can control it with the 107 (switching to 0-5v setting), and I have got mach3 working with it for on/off. However the spindle speed seems low. Just running a voltmeter over the terminals it measures 4.75v at full speed which seems to be 1000rpm. The terminal marked 10v on the Lenze control board is a 10v output which I am struggling to get my head around.

Did you set the Spindle pulleys up in Mach3 .? You'll find it on Config Menu.
Did you calibrate the 107 has per manual.?

The 10V output could be the supply voltage for if you want to use a Pot.?

Hi Jazz,

Yes I just calibrated the spindle and I did set the pulleys but just realised I had limited the rpm to 1000. Just increased this which has now sorted it. Thanks again.

Yes, the 10V is for the pot. You use the input and ground if your control board outputs voltage and ignore the 10V

Next question for you both.

Basically there is a spindle sensor, I assume it must be required for the auto toolchanger as it used to rotate the spindle to a specific angle prior to activating the tool changer. So was wondering how I go about determining details of this sensor.

At this moment in time I have found the wires that come from the sensor (pic attached). Wire colours are blue, green, yellow and red. Is there any relevance of wire colours for sensors?

Hello Steve,

Spindle sensor is for feeding back the spindle speed or for tapping synchronisation. Spindle position doesn't matter for the toolchanger. The spindle sensor will probably have 2 wires for LED and another 2 for the (photodiode) detector. The slots in the sensor disk cause the detector to pulse once per slot. Try and read any numbers off the sensor and look for a datasheet on the net. Don't worry about the ones with 5 leads as they have a different detector. They are not expensive to change if you need to.

I can't find any details on my wiring diagrams, sorry
