[Coast-to-stop function]
A signal input terminal is set to carry out coast-to-stop from an external location.

[Frequency signal changeover function]
A signal input terminal is set so that the frequency setting command can be changed from
the "command set with parameter P09" to the "external potentiometer".
(The state will not change if parameter P09 is set to "2 (potentiometer)".)

[2nd characteristics selection function]
The inverter will run with the data set in the 2nd acceleration time (parameter P39), 2nd
deceleration time (parameter P40), 2nd base frequency (parameter P41), and 2nd torque
boost level (parameter P42) when the SW signal is ON (closed).
[Set frequency
When the frequency setting is "digital setting with operation panel (P09=1)", the frequency
can be changed with SW1 and SW2 by setting parameter P21 to "8". The changed
frequency can be saved with SW3.
∗ When parameter P21 is set to "8":

If the signal input is turned ON (closed) during operation, "0.0" will appear and the
inverter output will immediately stop.
If the input signal is turned OFF (opened) and the run signal is ON, the inverter will
immediately start operation.
Note) The inverter will start as soon as the signal is turned OFF, so take sufficient
means to ensure safety.
If the signal input is turned OFF (opened) and the run signal is OFF, the inverter will
normally stop.
