Local control
The control commands are given from the control panel keypad or from a PC
equipped with Drive composer when the drive is in local control. Speed control mode
is available in vector motor control mode and frequency mode is available when
scalar motor control mode is used (see parameter
).
Local control is mainly used during commissioning and maintenance. The control
panel always overrides the external control signal sources when used in local control.
Changing the control location to local can be prevented by parameter
.
The user can select by a parameter (
) how the drive
reacts to a control panel or PC tool communication break. (The parameter has no
effect in external control.)
External control
When the drive is in external (remote) control, control commands are given through
• the I/O terminals (digital and analog inputs), or optional I/O extension modules
• the fieldbus interface (via the embedded fieldbus interface or an optional fieldbus
adapter module).
