Kinetix Servo Drives
Problem with kinetix servo drives.

We have 2 conveyor lines stacked one on top of each other. At the end of the line we have 2 placement belts with AB servo motors with kinetix servo drives that "place" our product on what we call a layup belt.

Both servos work well when used alone, but when both servos work at the same time, servo 2 gives me fault code s54 (velocity error).

What could be the cause? Could the PLC scan time be the problem? Scan time is good when 1 drive works but too long when both work.
