When the setting for the stiffness or inertia ratio results in a Kvp value of greater than 4000, it isn't useful
to increase stiffness anymore。For encoders with less than 80000PPR resolution, the maximum rigidity
level is 22.
4.3.4 Reasons for the failure of tunning
1.
Incorrect wiring
2.
The motor model is incorrectly set
3.
The pre-enable function is configured for the input port, but is disabled
4.
The set motor bearing is subjected to too much friction or other external forces
5.
There is a large mechanical gap between the motor and the load
6.
Very low mechanical rigidity
7.
The load inertia ratio is too large
8.
Load flexible connection
9.
Acceleration and deceleration is less than the viscous friction torque
Note
Complete the EASY process before using the tunE menu feature;
The self-tuning process may cause mechanical jitter, please be ready to cut off the driver power at any time;
In order to prevent unnecessary mechanical damage, please ensure that the motor has sufficient range of
motion before performing the self-tuning function.
