Immediat
e effect
The friction compensation function is to correct the viscous friction changes and fixed load changes, and adjust the
friction compensation coefficient. Usually, the friction compensation coefficient should be set below 95%. If the effect is
not obvious, please increase the friction compensation cut-off speed within a range of 10% without vibration.

e effect
The higher the set point is, the better the effect is. However, if the setting value is too high, the vibration of the response
will be more likely to occur. Usually, set the value below 95%.

e effect
The gain tuning value of the robust control is set. The larger the value is, the faster the system responds, but the overshoot
and noise of the system will be excessive.

e effect
The load factor of robust control is set. The larger the value is, the faster the system responds. However, the system noise
may be too large. When the inertia is large, increasing the value appropriately can reduce overshoot and overshoot.

The sensitivity of setting up the vibration is set. The smaller the setting value is, the more sensitive it is. If the setting is
too small, the vibration will be detected mistakenly.

Setting the threshold of vibration detection, the smaller the setting is, the easier it is to detect vibration. If it is too small, it
will detect vibration in normal operation.
