No action: No action is taken even if a timeout occurs.
Alarm: An alarm goes off if a timeout occurs. The message "" blinks at the left end of the
control panel.
Tripping: The inverter trips if a timeout occurs. The message "" blinks on the control panel.
Note) Changes to the parameters , , , do not take effect until the power
is turned off and
then on again. When inter-drive communication is used, the parameter
is set at 0.02 or more.
