Local control
The control commands are given from the control panel keypad or from a PC
equipped with Drive Composer when the drive is set to local control. Speed and
torque control modes are available for local control; frequency mode is available
when scalar motor control mode is used (see parameter 19.16).
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
19.17.
The user can select by a parameter (49.5) how the drive reacts to a control panel
or PC tool communication break. (The parameter has no effect in external control.)
