Configuration

Under the Basic config section of the Configuration tab, you will find the following settings:

Wind Offset – Wind Sensor Correction

To ensure accurate steering in all wind-based modes, your anemometer must be correctly aligned. Sail the boat under engine power directly into the wind, check the displayed wind angle, and adjust the offset here if needed.

A correct wind offset is especially important when using features like wind steering and tacking, where precise wind angle measurements are critical for performance.

Servo Manual Speed

This setting determines how quickly the drive accelerates to maximum speed. A higher value results in faster response; a lower value allows smoother, more gradual movement.

Servo Distance Direction Small

Defines the distance the drive moves when a single arrow key is pressed. Ideal for making small manual steering corrections in Standby mode.

Servo Distance Direction Big

Defines the distance the drive moves when a double arrow key is pressed. Useful for making larger manual steering adjustments.

Servo Mounted Left

By default, the TillerDrive is mounted on the starboard side. If you've installed it on the port side, enable this setting. The system will automatically reverse the steering direction accordingly.

Use External Compass

Enable this option if you’re using an external compass. The internal compass data will be ignored, and only the external compass values will be used for heading calculations.

Use APB NMEA Bearing

Determines whether the autopilot in APB mode follows:

• ON: the bearing to the waypoint (bearing to destination)

• OFF: the heading to steer provided by your plotter/navigation system

Enable Sound Alarm (Web Interface)

Turns the sound notification on or off for alarms played through the browser.

Swap Arrow Keys (ControlHead)

Allows you to reverse the direction of the arrow buttons on the ControlHead.

Advanced Config

Under the Advanced config section of the Configuration tab, you'll find the following settings, which apply only to the MotorController Advanced:

Servo Max Current

Sets the maximum allowable current for the Motor Controller. If this limit is exceeded, the Motor Controller will shut down to prevent damage. You can monitor the actual current under Actual.

Trim Current Warning

Sets a warning threshold as a percentage of the Servo Max Current (e.g., 90%). If this current level is exceeded, the system will issue a warning before the Motor Controller shuts down for protection. This feature only works when the value is set below 100%.

Clutch PWM

If you're using a clutch, this setting allows you to define the minimum PWM value required to engage it, significantly reducing power consumption.

Use Brake

Enables or disables the use of a brake.

Use End Switches

Enables or disables the use of end switches.

Max Controller Temp

Sets the maximum allowable temperature for the Motor Controller. If this limit is exceeded, the controller will shut down. The current temperature can be viewed under Actual.

Max Motor Temp

Sets the maximum allowable temperature for the motor. If this limit is exceeded, the motor will shut down. The current temperature can be viewed under Actual.
