Spindle Coolant Pump


I’m wiring up the Spindle coolant pump for the 2.2kw spindle, can someone give me an idea as to where the red,Black and yellow wires go, clearly the red and black are 12v power and I’m assuming the yellow is a signal wire, I just dont know if they go directly to power or to the Masso or to the VFD, any help is much appreciated.

Kind regards,



Ignore it, just Red positive, black negative, we have been cutting them off recently to avoid the confusion. There should not be a switch of any sort on this line, if the machine is on so is the coolant, this way you cannot forget to turn it on.
