0 ~ 100 Effective after Set
132AH
Setting description: Limits the maximum output of friction compensation control; if set as 100, then
the restriction value is the rated current value.

Setting description: Limits the friction compensation control gain; if set as 100, then the gain is 1.
Friction compensation adjustment method
1. Please set the friction compensation parameters as the default values.
2. Please set the load inertia ratio correctly (Cn025). If the load inertia ratio was not set correctly, it
may not be able to be controlled normally and vibrations will be generated.
3. Enable friction compensation control flag (tn841.0=1), and confirm the compensation effects.
4. Please keep the friction compensation limit value at a fixed value (tn842=50).
5. If sufficient compensation cannot be obtained, within the range of not generating vibrations, use
10% as the unit to increase the friction compensation gain (tn843). Please set the adjustment
range within 200%.
※ This parameter can be adjusted through off-line tuning
