30 External Device Communication – FNC270 to FNC276
30.2 FNC271 – IVDR / Inverter Drive
2. Inverter instruction codes
The table below shows inverter instruction codes which can be specified in .
For 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.
3. Related devices
→ For the instruction execution complete flag use method, refer to Subsection 6.5.2.
*4. Cleared when PLC power supply is turned from OFF to ON.
*5. Cleared when the PLC mode switches from STOP to RUN.
*6. Initial value: -1
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.
