Warning
A state entered in fault situations, for example if the drive is subject to an overtemperature or when the drive is protecting the
motor, process, or mechanism. The drive prevents a restart until the cause of the fault has disappeared. To cancel the trip state,
restart the drive. Do not use the trip state for personal safety.
Trip
When tripping, the drive suspends operation to prevent damage to the drive and other equipment. When a trip occurs, the motor
coasts to a stop. The drive logic continues to operate and monitor the drive status. After the fault condition is remedied, the drive is
ready for a reset.
Trip lock
The drive enters this state in fault situations to protect itself. The drive requires physical intervention, for example when there is a
short circuit on the output. A trip lock can only be canceled by disconnecting mains, removing the cause of the fault, and reconnect-
ing the drive. Restart is prevented until the trip state is canceled by activating reset or, sometimes, by being programmed to reset
automatically. Do not use the trip lock state for personal safety.
LCP notification
When a fault is triggered, the LCP indicates the type of fault (alarm, warning, or trip lock) and shows the alarm or warning number in
the display.
