Control input commands such as the Forward rotation command (STF) signal
and the Reverse rotation command (STR) signal can be set. (For the details,
refer to page 650.)
The states of the output signals such as the Forward rotation output, Reverse
rotation output, and Inverter running (RUN) signals can be monitored. (For
the details, refer to
Read the set frequency/speed from the RAM or EEPROM.
H0000 to HFFFF: Set frequency in 0.01 Hz increments
(The display can be changed to the rotations per minute using Pr.37, Pr.144,
and Pr.811. (Refer to page
Write the set frequency/speed into the RAM or EEPROM.
H0000 to HE678 (0 to 590.00 Hz): frequency in 0.01 Hz increments
(The display can be changed to the rotations per minute using Pr.37, Pr.144,
and Pr.811. (Refer to page
To change the set frequency consecutively, write data to the inverter RAM.

H9696: Inverter reset
As the inverter is reset at the start of communication by the computer, the
inverter cannot send reply data back to the computer.
H9966: Inverter reset
When data is sent normally, ACK is returned to the computer, and then the
inverter is reset.
