key lamp of an inverter front panel lights, priority is most given to operation by a
panel. (Refer to the inverter instruction manual for details).
When operation/stop is by the control terminal and only a monitor is by N2, set
the functional number 48 (communication priority release) to the unused control
terminal and turn on or set 48 to the always active function selection (
f110, or
f127 or f128).
Note) The local mode of the panel has priority over Metasys
