Hi,
some years ago I came across a big industrial plasma/oxy-fuel table, it was about 8m long and about 4m wide, a big sucker.
It had Mitsubishi servos and a Spanish(?) made drive Loggio....or something like that. They used the proprietory Mitsubishi bus protocol.
I can only assume the Spanish company paid a licence fee to Mitsubishi. The problem was that the drives kept blowing up, and they were $2500NZD each.
I suggested to the company that they get rid of the Dynapath control, which provided the bus control data stream to the servo drive, with a PC and Mach4 with a Hicon motion control.
To do this we used the more normal 'regular Mitsubishi drives' which have all the regular input features of all modern servos, ie Step/Dir input. We got four drives for
$1000NZD each and away we went. To my knowledge the same combination is in use today, eight years later.
May I suggest that you take a look at Delta servos. If you do you will find that they produce a number of different drives, including a bog standard Step/Dir input (or analogue)
but also various bus protocol types including Ethercat. The Ethercat model MUST be used in a Ethercat environment, its not possible to feed Ste/Dir into it.
Want you need to do is establish whether Mitsubishi made a regular Step/Dir (or analogue) input drive for your servo. If so then Mach3 would have no trouble driving it, but your
existing bus protocol drive is a no-go.
