Local and external control locations
There are two main control locations: local and external. Depending on the user
interface, select between the local and remote control as follows:
- Assistant control panel: Use the Loc/Rem key.
- Drive Composer PC tool: Change the Loc/Rem setting.
 Local control
The control commands are given from the external control panel or from a PC
equipped with Drive composer when the drive is in local control. 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
.
You can use parameter
20.28
to select how the drive reacts when the control
location is switched between local and external. Use parameter
49.05
to specify
how the drive reacts to a control panel or PC tool communication break. (The
parameter has no effect in external control.)
