5-9 Functions Relating to Protections, Warnings and Various Output Signals

Alarm Signal (AL)

Upon detecting an overcurrent, overvoltage or other error, the Inverter stops the output and
outputs an alarm signal (AL). This is called a "trip."
When the Inverter is reset, the trip status is reset and the alarm signal also turns OFF. A trip
can be reset by pressing the STOP/RESET key or turning the reset terminal ON and then OFF.
(Some trips may not be reset using the reset terminal depending on their cause. In this case,
the power must be reconnected. )
Allocate "05: AL (Alarm output)" to any Multi-function Output Terminal Selections (C021 to
C022) or Multi-function Relay Output Function Selection (C026). (This function is allocated to
the relay in default setting.)
The relay is based on SPDT contact. For details, refer to "Multi-function Output Terminal
Contact Selection" on page 5-34.
