text: <s>[INST] 1336 Plus Overvoltage Fault only in the Forward Direction. I have never seen this before, but I am getting a high bus voltage only when the drive is running in the Forward Direction. In reverse, the bus voltage is only 670- 680. In forward, the bus voltage runs up over 800 and then trips. I have tried changing the Decel rate and there is already a braking resistor on the drive. Does anyone have any suggestions on this problem? Can I do something to fix this or do I need to change the drive? [/INST] Overvoltage faults are caused by the load decelerating too fast, this causes the motor to become a generator and hence the DC bus has to absorb the extra energy. You can extend the deceleration or add larger resitors. The drive is operating as designed \\n </s>
