Run command (expansion) Set speed (RAM)
Run command (expansion) is same as instruction
code HF9 (Refer to page 219)
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)
Rotation speed
(output frequency)
Drive unit status monitor (expansion) is same as
instruction code H79 (Refer to page 220)
The unit of speed (frequency) 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.
Replys the monitor item specified in instruction
code HF3 for special monitor. (Refer to page 218)

Drive unit status monitor
(expansion)
Special monitor
4
First monitor value Second monitor value
The first monitor value and second monitor value
store the monitor data specified by the sending
data type 4.
When the sending data type is not 4, the first
monitor value stores the current monitor and the
second monitor value stores the rotation speed
monitor.
The unit of speed (frequency) 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.
