5.4.1 Precautions for auto tuning

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 minimum distance for the motor to accelerate from zero
speed to the constant speed zone as the traveling distance, and the constant speed is equal to
the set jog speed. If the traveling distance is too long, the estimation time is longer, too. For
mechanical parts with long lead, 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.
1.
The movement speed of the mechanical part is lower than 200 rpm.
2.
The traveling range of the mechanical part is shorter than the traveling distance when the
3.
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.
1.
The load inertia ratio of the mechanical part is greater than 50 times.
2.
The bandwidth of the mechanical part is lower than 10 Hz.
3.
The viscous friction of the mechanical part is high.
4.
The torque limit of the mechanical part is too low.
