*1 Please set "0" to instruction code HFF (Link parameter expansion setting) just before the IVCK instruction when reading frequency.
When "0" is not set, reading of the frequency may not be executed normally.
Inverter Operation control
The table below shows instruction codes for writing to the inverter which can be specified by IVDR instruction (Page 105)

*1 The instruction code "HFD (inverter reset)" does not request a response from the inverter. Accordingly, even if inverter reset is executed
in a station number to 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 (s3) of the IVDR instruction.
Do not use H9966.
*3 Please set "0" to instruction code HFF (Link parameter expansion setting) just before the IVDR instruction when writing frequency. When
"0" is not set, writing of the frequency may not be executed normally.
Parameters
For inverter parameters which can be changed (read/write), refer to the manual for each particular inverter.
