
Communication settings
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). Set Pr.160 (User group read selection) to 0 [The
simple mode and extended parameters can be displayed] before making the parameter settings.
Do not change these parameters, even though they can be monitored from the GOT. If they are changed,
communication with the GOT is disabled.
