Troubleshooting
A trip is the action following an alarm. The trip coasts the
motor and is reset by pressing [Reset] or by a digital input
(parameter group 5-1* Digital Inputs [1]). The origin event
that caused an alarm cannot damage the frequency
converter or cause dangerous conditions. A trip lock is an
action when an alarm occurs, which could damage the
frequency converter or connected parts. A trip lock
situation can only be reset by a power cycling.
