Why does the 8839 Econo Flex unit with an analog I/O card installed, PI control is enabled, and with AI3 as the manual speed reference begin to run backwards as the pot is turned down low, but in manaul mode, the drive runs fine at higher speeds?

The possible solution is to install the 100 ohm resistor in series with speed pot leg on COM terminal.
