Yaskawa is pretty close lipped when it comes to revealing technical details. They are not my favorite company to deal with. One problem I have had with Yaskawa drives and motors is that if you want buy some cable for an older motor/drive combo they really put the screws to you. On a recent job, it was cheaper to buy new Teco servo drives, motors, and cables than it was to just buy just replacement cables from Yaskawa. Their prices were crazy high. Apparently some of the older Yaskawa drives used special connectors that are not readily available now. And that was for year 20002001 vintage Yaskawa servos.
