The inverter mode cannot be changed just setting b171. After setting b171, be
sure to execute initialization to activate new mode.
Actual inverter mode can be monitored with d060.
Once high frequency mode is set, initialization can be done just by setting
b084, b085, b094 and setting b180, it is not needed to set b171 .
