General Mach Discussion / Re: z axis - ac servo motor with brake - does it unlock automatically

aha = thanks
so the brake on a z axis is only used for when the machine is switched off,
for example if you had the z at its upper most position on a large machine and then switched off the power to it, the weight of the spindle and big heavy motor would pull the axis down so it would slam into the lower end stop!!
= get it.
thank you.
by the way, I wonder if you wouldn't mind trawling through that minas A4 catalougue - as it appears that you can simply fire in 5v step and direction into the drives = surely it cannot be that simple?
oh p.s. do you happen to know at what wattage the isel fb2's run/ran at?
