7. Applied operation

Applied operation can be performed by selecting the frequency mode and command mode setting. However in

case the LOCAL mode is selected by key (lighting a LOC/REM lamp), frequency setting mode and command mode are fixed operation panel key setting mode. The following explanations are applied REMOTE mode only.

7.1Setting the operation frequency

Applied operation can be performed by selecting the inverter frequency setting. To make settings for applied operation, use the basic parameter HOQF (selection of frequency setting mode 1), and the extended parameters H (frequency priority selection) and H (selection of frequency setting mode 2).
