Connecting a PC tool to a drive through the control panel
You can use the control panel to connect an ABB PC tool to the drive. When using the
control panel, you can only access the drive from the PC tool.
1. Install an ABB PC tool to the PC.
2. Connect the control panel to the drive.
3. Connect the control panel to the PC with a USB cable as instructed in Connecting
control panel to PC USB (page 58 ).
4. If Windows prompts you to install USB drivers, install them as instructed in Drive
composer user’s manual (3AUA0000094606 [English]).
The behavior depends on the current control location of the drive. See Connecting in
local control mode (page 59 ) and Connecting in remote control mode (page 59 ).

Connecting in local control mode
When you connect the control panel in local control mode to a PC, local control is
transferred to the PC tool and the control panel displays the USB screen. The drive
retains its present reference and direction.
When you have finished using the PC tool, close the connection through the PC tool
first and then disconnect the USB cable. Local control is transferred back to the
control panel and the drive retains its present reference and direction.
Note: If you disconnect the USB cable before closing the connection, a Local loss
fault is triggered.

Connecting in remote control mode
When you connect the control panel in remote control mode to a PC, the control
panel displays the USB screen and you can only interact with the control panel
through the PC tool. The drive remains in remote control, but you can switch over to
local control using the PC tool.
When you disconnect the PC tool, the control panel exits the USB screen and the
drive resumes its normal operation.
