* No terminal outputs a signal during normal operation.
 Performing forced operation “FMRUN” assignment (Function code data = 95)
An ON signal is output during forced operation. ( Function codes H116 to H121)
 Warning “L-ALM” assignment (Function code data = 98)
This output signal comes ON when a warning occurs. ( Function codes H81 to H83)
 Alarm output (for any alarm) “ALM” assignment (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” assignment (Function code data = 101)
The signal comes ON when any error is detected in the circuit for EN terminal.
