■9. Connecting FREQROL-F700PJ series
Make the communication settings of the inverter.
Be sure to perform the inverter reset after updating each parameter.
(1) Communication port and corresponding parameters
GOT connection destination
PU connector
(2) Communication settings of inverter
Set the following parameters using the PU (parameter unit). Before setting the parameters, set Pr.160 (Extended
function display selection) to 0 so that simple mode + extended mode parameters are displayed.
Do not change these parameters, even though they can be monitored from the GOT. If they are changed,
communication with the GOT is disabled.
