* When external fault stop signal is set to B contact input, fault reset can be applied after run signal
is turn OFF, even if external stop signal is "OPEN". However, if turn the run signal ON again, a
fault trip will occur.
Turn the external fault stop signal "CLOSE", and then turn the run signal ON to apply the normal
operation.
Parameter setting disable function
Used to set the signal input terminal for disabling the parameter setting through external control.
•EAfter signal input is turned ON, setting parameters with the operation panel and communication is
disabled.
•EWhen the signal input is in ON state, function parameters and built-in memory parameters settings
are all disabled. Only monitor can be applied.
•EIn the process of data setting, SW cannot change the data even if the SET button is pressed when
the signal is ON.
Coast-to-stop function
Used to set the signal input terminal for applying coast-to-stop through external control.
•EDuring operation, when the signal input is turned ON, "0.0" will be displayed and the inverter will
stop output immediately.
(NO fault indications and fault alarm output will be output.)
•EWhen the signal input is turned OFF, the inverter will start operation immediately after run signal
is turned ON.
[Note] If signal is turned OFF, the inverter may start simultaneously. Ensure personal safety before
operation.
•EWhen signal input is turned OFF, the inverter is normally stopped after the run signal is turned OFF.
