through E05 are considered to be inactive.
Multistep frequency
Frequencies set to function codes C05 through
C19 can be selected according to external digital
input signal switching. Set data 0 to 3 to the
desired digital input terminals and combination of
input signals determines the selected frequency.

3-wire operation stopcommand [HLD]
Used for three-wire operation. When HLD-P24 is
ON, the FWD or REV signal is maintained, and
when it is OFF, the signal is reset.

Note : The inverter operates while FWD-P24 or
REV-P24 is ON even if HLD-P24 is OFF. An
external interlock sequence ,which makes
FWD-P24 and REV-P24 OFF when HLD-P24 is
OFF, is required.
