Spindle coolant flow alarm input

[jv]

Hi All.
I use a water cooled vfd spindle on my router cnc. I've connected a water flow meter (switch type) to the MASSO G3 controller using the 'spindle coolant flow alarm input'. If I stop the water flow to the spindle the controller 'errors' and the spindle stops but while the spindle is slowing down the tool path program continues to run until the spindle as come to a standstill.

I would have expected the the machine stop first while the spindle came to a halt or am I doing something wrong.

Hi. All
Sorry to reply to my own post but I've found out what the problem was.

When I dropped the power to the coolant pump the power to the vfd was dropped also, so the 'Spindle Coolant Flow Alarm Input' didn't act as expected. Having tested the 'flow input' again it all works as expected.
