Code E019

I have a tough one. Codes E019 at full acceleration FWD & REV. Jungheinrich control. Already glued the ribbon cables in the controller, swapped controllers with a known good one, removed L1, L2 & L3 cables looking for rub marks. The book tells me the controller sees a 15% variance in one of the phases. Checked the motor windings and short to frame- ok
Any ideas? Thanks

Check the amperage on each phase.

The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
