*1. The instruction code "HFD (inverter reset)" does not request a response from the inverter.
Accordingly, even if inverter reset is executed to a station number at which an inverter is not
connected, error does not occur.
It takes about 2.2 seconds to complete execution of inverter reset.
*2. When resetting the inverter, please specify H9696 as the operand
Do not use H9966.
*3. Please write "0" to instruction code HFF (Link parameter expansion setting) just before the IVDR
instruction when writing frequency.
When "0" is not written, writing of the frequency may not be executed normally.
