Inverter Operation Control Instruction (PLC
Inverter) [FNC271 / IVDR]
This instruction writes a control value required to operate an inverter from the PLC to the inverter.
9.5.1
Function and operation
When an "instruction code" specified for computer link operation in the inverters is specified in the IVDR
(FNC271) instruction, the value specified in
is written to the specified item of the inverter.

Inverter instruction codes
The table below shows inverter instruction codes which can be specified in
.
For the instruction codes, refer to the pages explaining computer link in detail in each inverter manual.
*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
of the IVDR instruction.
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.
