2. Inverter instruction codes
The table below shows inverter instruction codes which can be specified in
. Only use the instruction codes
shown below. Use of instruction codes not shown below may cause communication errors.
Do not use instruction codes not shown in the table below. They may cause communication errors.
For the instruction codes, refer to the pages explaining computer link in detail in each inverter manual.

Please write "0" to instruction code HFF (Link parameter expansion setting) just before the IVCK instruction
when reading frequency.
When "0" is not written, reading of the frequency may not be executed normally.

Cautions
→ For other cautions, refer to the Data Communication Edition manual.
• It is not permitted to use an "RS (FNC 80)/RS2 (FNC 87)"/"ADPRW (FNC276)"/"FLCRT (FNC300) to FLSTRD
(FNC305)" instruction and an "IVCK (FNC270) to IVMC (FNC275)" instruction for the same port.
• Two or more inverter communication instructions (FNC270 to FNC275) can be driven for the same port at the same
time.
