ESC Calibration (ArduPilot)

The ESC page configures Electronic Speed Controller output parameters and provides ESC calibration for ArduPilot vehicles.

Configuration

• Output type — PWM output protocol: Normal / OneShot / OneShot125 / DShot150/300/600/1200 (MOT_PWM_TYPE). For QuadPlane VTOL, uses Q_M_PWM_TYPE.
• Output PWM min — minimum PWM value sent to ESCs (MOT_PWM_MIN)
• Output PWM max — maximum PWM value sent to ESCs (MOT_PWM_MAX)
• Spin when armed — motor spin level when armed but not flying (MOT_SPIN_ARM)
• Spin minimum — minimum spin level during flight (MOT_SPIN_MIN)
• Spin maximum — maximum spin level (MOT_SPIN_MAX)

When a DShot output type is selected, additional settings appear:

• DShot ESC type — ESC protocol variant (SERVO_DSHOT_ESC)
• DShot output rate — DShot frame rate (SERVO_DSHOT_RATE)

Calibration

WARNING

Remove all propellers before calibrating ESCs.

Press the Calibrate button to run the ESC calibration procedure. This sets ESC_CALIBRATION = 3, which triggers the ESC to learn the throttle range on the next reboot.
