Perform an autotune
Warning: A rotating autotune will cause the motor to accelerate up to 2/3 base speed in the
direction selected regardless of the reference provided. Once complete the motor will coast to a
stop. The enable signal must be removed before the drive can be made to run at the required
reference.
