Troubleshooting an oV DC Bus Overvoltage Fault |
|
||
An oV (DC Bus Overvoltage) fault is triggered when the DC bus voltage rises higher than the overvoltage trip point. Note: On smaller drives with a LED segment display such as the V1000 and J1000, a DC Bus Overvoltage fault will appear as "oU". The oV trip point is approximately:
Possible causes:
Note: The drive's fault trace can provide more information on what happened at the time of the fault (U2-xx). |

The following are possible solutions for a DC Bus Overvoltage (oV) fault. These are not in any particular order.
Note: Not all parameters will be available on all drives. |
