Select the present inverter as the master or the slave.
F1-20
Set on the master inverter. Select the frequency setting command of slave inverter sent
by master inverter, and then send F0-07 or F9-06 to the slave inverter.
F1-21
When the inverter is the slave, (the frequency sent by master inverter* F1-21) will be
the setting numeric frequency of the slave inverter.
