Operation Mode Switches
Switch SF1 is used to select the working mode to prevent incorrect operation.
•
Auto: Allows switching to PF bypass automatically when the drive is in a serious fault.
•
Manual: Allows manual switching to working-frequency bypass according to the real production requirements when the drive is
normally running.
•
Forbidden: If the production conditions do not allow the switching to working-frequency bypass, this mode can be selected to
prevent incorrect operation.
