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.
Autotune 00.040 (05.012) = 2 Motor loaded stationary autotune = 1
Motor unload/uncoupled autotune = 2
