*No terminal outputs a signal during normal operation.
■
Light alarm – “L-ALM” (Function code data = 98)
This output signal comes ON when a light alarm occurs. (
Function codes H81 and H82)
■
Alarm output (for any alarm) – “ALM” (Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter enters Alarm mode.
■
EN circuit failure detected – “DECF” (Function code data = 101)
The signal comes ON when any error is detected in the circuit for EN terminal.
■
EN terminal input OFF – “ENOFF” (Function code data = 102)
The signal comes ON when the EN terminal is turned OFF.
