You can forcibly turn on/off the external I/O terminals and CC-Link remote inputs/
outputs.
For inputs, the input signals from the outside or CC-Link to the inverter are ignored.
For outputs, the output signals from the inverter to the outside or CC-Link are ignored.
* The parameter values set using the FR-PU04 are all decimal numbers.
* When the control input terminals are turned on forcibly, they are enabled in the external/CC-
Link operation mode.
<Setting method>
Make setting after converting a bit string (binary) into decimal.
<Example>
When turning on control input terminals STF, RM forcibly
Bit (binary) 00001001 → 9 (decimal)
