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

David

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?
