Example 5.
Rewrite the values of parameters 01-10(P.0), 01-00(P.1), 01-01(P.2), 01-03(P.3), 04-00~04-02/P.4~P.6, 01-06~01-
07/P.7~P.8, 06-00(P.9), 10-00~10-01/P.10~P.11 by the inverter
Step 1: The host computer sends message to the inverter for writing the value of01-10(P.0), 01-00(P.1), 01-01(P.2),
01-03(P.3), 04-00~04-02/P.4~P.6, 01-06~01-07/P.7~P.8, 06-00(P.9),10-00~10-01/P.10~P.11.
