Might give that a try when its done as it may work better than Step/Dir spindle in the SS/ESS
The axis motor would stop instantly with an ovetravel so even less than a second to dissipate the power wouldnt be an issue. However the big drives I use have shunt circuitry and the wee drives I use active shunts, what it would be like without the shunts I dont know.
I just downloaded that manual and see the circuit you are talking about, strange thing is I cant seem to find anything similar in the 3000's manual I have. Have done a search and neither "Emergency Stop" or "Contactor Wiring" or" Emergency Stop Contactor Wiring" gives a hit, wonder why they would have it in the 5000 manual but not the 3000 ones?
