Hi,
I think I am not the only one that hates the Spindle Motor Fan's sound as soon as you flip the main power switch. It starts even before I start the NC and the spindle motor itself is running. I think this is unnecessary if I only want to do some work on the machine without the need to run the spindle.
The fan is a 220V AC unit and is mounted at the top of my 5.5 / 7.5 kW Mitsubishi spindle motor. I would like to control the fan by a relay that use a signal from the Spindle driver. I want the relay to make contact when the spindle motor starts, hold the contact while the spindle runs and after the spindle is stopped, continue to hold contact for the fan for another 15-30 min. ( I want to use one of those bathroom fan electronic thingy's for the delayed fan stop function).
Can anyone experienced with spindle drivers help with info about which signal to use to activate the relay. I do not want to experiment myself and thereby risc to ruin my driver.
