9.3 Warnings and Alarms
9.3.1 Warning and Alarm Types
Alarm
An alarm indicates a fault that requires immediate attention. The fault always triggers a trip or trip lock. Reset the drive after an alarm
using 1 of the following methods:
• Press [Reset]/[Off/Reset].
• Digital reset input command.
• Serial communication reset input command.
• Auto reset.
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 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 reconnecting 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.
