variable speed drive
I had a problem with a variable speed drive this morning after a power outage.the drive failed to come on after the power was restored.i therefore opened the unit to check whether a fuse or breaker had blown or tripped.very luckily there was a miniature circuit breaker which had tripped. But could not reset upon several attempts.But when i took off the main supply and as well reset the breaker, it was able to hold after restoring the power.what could be the cause?
The breaker supplies 240v/48v trasformer. |
