Recommended settings for auto tuning

Jog speed: 500 rpm or above.
1.
Acceleration time from 0 rpm to 3000 rpm or deceleration time from 3,000 rpm to 0 rpm:
2.
within 200 ms.
Traveling distance: 1 revolution or above.
3.
Description: it is advisable to set the traveling distance as the minimum distance for the motor to
accelerate from zero speed to the constant speed zone, with the constant speed equal to the
set jog speed. If the traveling distance is too long, the estimation time is longer, too. For
mechanical parts with long strokes, it is recommended that you set the traveling distance as the
working range for operation.
Auto tuning cannot be done in the following systems
 The mechanical part only moves in a single direction.
 The movement speed of the mechanical part is lower than 200 rpm.
 The effective stroke of the mechanical part is shorter than the traveling distance when the
motor rotates 0.5 revolution.
Auto tuning cannot be correctly done in the following systems
 The load inertia ratio of the mechanical part changes drastically.
The load inertia ratio of the mechanical part is greater than 50 times.

 The bandwidth of the mechanical part is lower than 10 Hz.
 The viscous friction of the mechanical part is high.
 The torque limit of the mechanical part is too low.
