How to enable spindle with a button was created by Clive S
I would like to fit a button to enable the spindle to lock it (servo motor) so that the draw bar can be undone. (might be a bad idea)

Could this be done with a on screen button (Axis)

I have this in HAL
### +24V to output 00 +ve then 00 -ve to servo drive +ve pin 9 then servo drive -ve pin 6 to gnd
net spindle-enable  =>  hm2_7i96.0.ssr.00.out-00

I do not think that would work, and would risk overloading the motor/drive.
Guestimating that a human will exert about 20 to 30 NM of torque on the screw, the motor would have to handle more than that to stay put while tightened/un-tightened.

The motor is 1.8Kw servo
