I have one DM556 driver that is capable of 4A RMS maximum.

That is all.

Yes, that is all the drive can do but does the motor actually need 4.6 amps to run his machine? My guess probably not.

Hard wired button. If you add an ATC you would use a motion.digital pin in the ATC stubs to activate, but you would still need the manual button for hand the spindle to store in the carousel.
