Run command (expansion) is same as instruction code HF9
(Refer to page 457)
The unit of set frequency is always by four digits, even when "0.01
to 9998" is set in [ Pr. 37 ] and "01" is set in instruction code HFF.
Inverter status monitor (expansion) is same as instruction code
H79 (Refer to page 457)
The unit of speed monitor is always by four digits (rounds down
after the decimal point), even when "0.01 to 9998" is set in [ Pr. 37 ]
and "01" is set in instruction code HFF.
Replies the monitor item specified in instruction code HF3 for
