Probably the cheapest method is to use 220-440 step-up transformer. Much cheaper than replacing servo drives which are most likely 440 volt. The earliest 432 control that I ever saw, was from the early 1980's. It was replaced in the early 1990's by the 532. There were several versions of the 432 during that production run. The 432-12 was the last, I believe. The 432-10 was the most common around here. |
