Local control vs. external control
The drive can receive start, stop and direction commands and reference values from
the control panel or through digital and analog inputs. Embedded fieldbus enables
control over an open fieldbus link. A PC equipped with DriveWindow Light PC tool
can also control the drive.
 Local control
The control commands are given from the control panel keypad when the drive is in
local control. LOC indicates local control on the panel display.
The control panel always overrides the external control signal sources when used in
local mode.
