I replaced some 15-20 year old Yaskawa motor/drives this year. We needed to get longer cables but they had used some special connectors that were obsolete. The price for the replacement cables (they were not sure they could even get the connectors from Japan if we ordered new cable sets) was more than the cost of new servo motors, drives, and cables.
So we ripped out all of the Yaskawa equipment and went with all new Teco servos and saved money. Although the motors and drives are working now, you might want to consider what replacing a component would cost, as eventually everything fails. And chances are that if you do the conversion, they will call you when a drive goes down in the future. Dave On 9/29/2015 1:55 PM, Marius Liebenberg wrote: > Ted > The machine is 15 years old.
