Tune the Current Loop (AUTOTUNE)

The AUTOTUNE function tunes the current loop automatically and sets the proportional gain, integral gain, and the discontinuous/continuous
breakpoint for optimum drive response for a given motor. The drive cannot achieve peak performance without properly setting these parameters.
Perform a complete AUTOTUNE procedure at least once with each controller/motor combination or if the motor armature or field windings have been
rewound.
NOTE
AUTOTUNE may not work on motors with either very long or very short time constants (for example, very short time constant permanent
magnet motors). In these instances the current loop must be tuned manually. Contact Parker SSD Drives Customer Service for assistance.
When clamping the motor, you must use a clamping force equal to or greater than the motor torque rating.
AUTOTUNE can be used for shunt wound, compound wound, and permanent magnet motors. The shaft on compound-wound and permanent magnet
motors must be locked for AUTOTUNE to work. For shunt wound motors, the shaft may need to be clamped if a residual field causes the motor to
rotate during AUTOTUNE. Any rotation of the motor during the AUTOTUNE procedure causes AUTOTUNE to abort.
Make sure it is safe to power and turn the motor and that operation of the motor and the drive will not pose a
