Hey guys,

     I'm looking into adding a 4th axis to my matsuura mc500v retrofit. Since the ip-a is an analog controller, I'm not sure there are a whole lot of options out there for guys wanting A and B axis. Most if not all the 4th axis I've seen on ebay appear to be digital in nature. Anyone know of a good older model 4th axis that will take + or - 10v? Thanks!

Almost any industrial 4th axis will be servo driven and the drive will determine whether it is analogue or step/direction control. 99.99% will be analogue I would think.

You should be able to more or less buy any 4th axis and fit a servo to it if the current motor is not suitable and then use a suitable drive that accepts analogue commands..
