Boxford 190vmc upgrade

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

Has Dave says will be for spindle feed back and the colours will probably be something like this but they could be anything has well.
Red = 5v (For LED)
Grn = 0v(gnd)
Yel = Signal +
blu = Signal -

If it's like most of these Slotted Optical sensors fitted on these machines there will be 2 slotted sensors, one for RPM signal and one for Index signal wired together each with 4 pins. Model number will be something like 306-061
pin1 = Signal +
pin2 = signal -
Pin3 = Led -
Pin4 = Led +

Like Dave said you really need the switch model number.

Hmm,

I tried to run my spindle in reverse last night. I have changed the settings to give a long delay between start and stop but the spindle only seems to be going one way. I assume it must be something simple I am missing. Also managed to get some photos showing the inside of the spindle and it's sensors. Will post later when I get chance.

How are you trying to do this.? . . . How do you have it setup.?
