This is not a PLC issue but I'm hoping someone can offer some help.
We have 2 axes with 50 HP motors and 1336 FORCE drives. One axis has been faulting out beacuse the braking resistors are overheating. The drive was replaced, chopper module swapped, the usual stuff. What's odd is that on the axis that's faulting both direction LEDs are on simultaneously (before and after the drive was replaced). According to the manual the direction LED should only indicate the direction of motor rotation for the axis. This may not be related to the braking resistor problem but I would like to know why it occurs with one axis and not the other identical axis.
