may result in the frequency converter issuing an alarm. A

tripped, which means that the frequency converter
suspends operation to prevent frequency converter or
system damage. The motor will coast to a stop. The
frequency converter logic will continue to operate and

reset. It will then be ready to start operation again.

Press [Reset] on the LCP

converter status. Remove input power to the frequency
converter, correct the cause of the fault, and reset the
frequency converter.
