6.4 Auto-tuning
6.4.1 Overview
Auto-tuning is divided into internal instruction auto-tuning and external instruction auto-tuning.
Auto-tuning (internal instruction) refers to the function of automatic operation (forward and reverse
reciprocating motion) of servo unit without instructions from the upper device and adjusting according
to the mechanical characteristics in operation.
Auto-tuning (external instruction) is the function of automatically optimizing the operation according
to the instructions from the upper device.
The automatic adjustments are as follows:
 Load moment of inertia
 Gain parameters (speed loop, position loop, model loop gain)
 Filter (notch filter, torque instruction filter)
6.4.2 Notes
Untunable occasions
 Mechanical systems can only operate in one direction.
Setting occasions that are prone to failure
 Excessive load moment of inertia;
 The moment of inertia varies greatly during operation.
 Low mechanical rigidity, vibration during operation and failure of detection positioning;
 The running distance is less than 0.5 circles.
Preparations before auto-tuning
 Use position mode;
 Driver in BB state;
 Driver without alarm;
 The matching of the number of pulses per rotation and the width of positioning completion
should be reasonable.
6.4.3 Operation tools
Internal instruction auto-tuning and external instruction auto-tuning can be executed by driver panel
and XinJeServo software.
