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). The original 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 cycling power.
