Why does the overload relay trip when try to run through the 8839 Econo-Flex drive at certain speeds but can run motor in bypass with no problem and currents are not excessive?

Have identified that on some some 75hp Econo-Flex OL relays they may trip a low freq.
These drives are using a LR9D5569 ( solid state OL - have found solid state devices don`t work exceptionally well on output of drives)

You can jumper out the points 95 / 96 for running in drive mode only and use the drive overload for protection until get replacement overload.

Will need to change out overload and use part number LR2D4365.
