Offline Auto Tuning
Offline Auto Tuning automatically detects inertia ratio, friction
coefficient, and resonance frequency, and sets basic gains accordingly.
Please set SEt-69 as below according to the type of the system.
The execution procedure of offline auto tuning is as below.
1. Offline autotuning (USr-02) is executed automatically.
2. Inertia ratio and system gain are automatically set.
3. 5 different basic gains are automatically set.
4. The response of drive will be improved.
The value set on the third digit of SEt-58 represents
100 RPM. For instance, if the set value is 8, it
means 800 RPM.
Revolution speed can be set at offline auto tuning.
Inertia ratio (SEt-66) can be directly set by the user.
Online Auto Tuning
Online auto tuning is used when the load constantly changes during
operation. It constantly changes the gain value according to the status
of the load in order to maintain response of the system even if the
status of the load changes.
In the following cases, offline auto tuning is better than online auto
tuning.
• When the inertia ratio of the load changes minutely or rapidly during
operation.
• When the inertia ratio of the load alternates between two values
• When a large torque is not generated during the operation because the
acceleration or deceleration time is too long, or the maximum revolving
speed limit or torque limit is set low.
