Start PID Controller Calibration

Initiates the automated PID controller calibration process for the active hold position feature. This endpoint starts an automated calibration routine that optimizes the PID controller parameters for maintaining precise motor position control.

The calibration process performs a systematic tuning sequence that oscillates the motor position in small increments while automatically determining optimal PID gains. During calibration, the reel will move small amounts (a few degrees) as the system tests different parameter values. The system will either complete successfully when it finds the ultimate gain value or timeout after 45 seconds and cancel the procedure automatically.

This calibration is typically performed at the factory and should not be necessary during normal operation. The process requires the motor position encoder to be installed and the active hold position feature to be enabled in system settings. Ensure adequate unwound cable length (approximately 1 meter minimum) before starting calibration to accommodate the automated movement sequence.
