Danfoss VLT Active Front End AFE 302 Operating Instructions Manual page 68

How to Programme
A trip is the action when an alarm has appeared. The trip will stop the AFE operation and change the digital output at
terminal 27 to Low, which will result in coasting the motor. It can be reset by pressing the reset button or make a reset by
a digital input (parameter group 5-1* Digital Inputs [1]). The origin event that caused an alarm cannot damage the AFE or
cause dangerous conditions. A trip lock is an action when an alarm occurs, which may cause damage to AFE or connected
units. A Trip Lock situation can only be reset by a power cycling.
