# Tool Motor Tuning

A motor tuning adjusts the tool’s motor control unit to optimize the performance and minimize loss.

For cable tools a motor tuning should be performed on each specific combination of controller and tool together. STB tools can be moved to another controller without the need to perform a new motor tuning.

Before performing the motor tuning, make sure the tool is connected to a virtual station and that the controller is set up to perform tightening.

The motor tuning takes approximately 1 minute to perform and rotates the spindle in both clockwise (CW) and counterclockwise (CCW) directions before it is finished.

For tools configured with open end Gear Front Attachment (GFA), remove the open end extension from the tool before performing the motor tuning.

## Performing tool motor tuning

1. On the home view, go to the Tool tab, select the tool to be motor tuned and go to Motor tuning.

2. Select Perform, and then press the trigger on the tool.

3. Select OK to start the Motor tuning.

   Follow the instructions on the screen and keep pressing the tool trigger until the motor tuning is done.

   - If the motor tuning is successful, an OK event is displayed.

   - If the motor tuning is not successful, or the tool trigger was released before the motor tuning is done, an NOK event is displayed.
