2. Program example
9.5.2 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.
