Inverter Mode Selection
Changing the setting of Inverter Mode Selection alone does not change the mode. After
changing this setting, perform an initialization/Mode Selection Command (b180). When the
Inverter mode is changed, the fault monitor data is cleared and the parameters are initialized.
The current Inverter mode can be monitored using d060.
Although the maximum output frequency of the 3G3MX2 is 400 Hz, switching to the high-
frequency mode permits output of up to 1,000 Hz. Since the high-frequency mode is supported
only in the heavy load rating setting, set the high-frequency mode after selecting Heavy Load
Rating (b049 = 00). (The rating type cannot be changed to light load when the high-frequency
mode is selected.)
To perform initialization or clear the fault monitor data while in the high-frequency mode, set
appropriate values in b084 and b094 and then perform initialization via b180 according to the
normal initialization procedure. It is not necessary to set a value in b171.
 Sensorless vector control operation cannot be performed in the high-frequency mode.
