(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
Parameter No.
