Run command (expansion) is same as instruction code HF9
(Refer to page 201.)
The unit of set speed (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.
Drive unit status monitor (expansion) is same as instruction code
H79 (Refer to page 202.)
Rotation speed (frequency) monitor is in 1 increments. (Numbers
after the decimal point are rounded.)
Replies the monitor item specified in instruction code HF3 for
special monitor.(Refer to page 200.)
