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

Parameters corresponding to inverter

destination

 

PU connector

Pr.79, Pr.117 to Pr.124, Pr.340, Pr.342, Pr.549

 

 

(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.
