Hi,
either <Stop> or <Estop> do not de-accelerate, they crash stop.
There is settings within your servo drive that limit current, or analogously torque, which will be a bit more graceful.
If you make this setting just a little more aggressive than the max acceleration you have set Mach to then it will not interfere
with normal operations but will effectively provide a max de-acceleration slightly in excess of that.

Thanks Peter and Craig,
Yes Peter I know it is an emergency stop, necessitating a stop as quickly as possible, and it does make sense to turn everything off immediately, regardless of the cost in mechanical terms.
However I did hope that there was perhaps an option for the stop button on M3, that perhaps wasn't quite so aggressive as an Estop.
Craig I think you have the answer with your suggestion about the decceleration period of the spindle motor being set within the servo controller, is the answer. I'll try it and get back to you with the result.
Thanks
Dave
