6.5.5 Friction compensation
The friction compensation function is a function that compensates for viscous friction variations and fixed load variations.
The friction compensation function automatically adjusts the auxiliary functions with.

Precautions
●
When using the friction compensation function, set the rotational inertia ratio (Pn100) as
correctly as possible. If the rotational inertia ratio is set incorrectly, vibration may be caused.

Pn161 = 100 (friction compensation gain of 100%).
Pn162 = 100 (2nd friction compensation gain is 100%)
Pn163 = 0 (friction compensation factor of 0, no compensation).
Pn164 = 0 (friction compensation frequency corrected to 0 Hz).
Pn165 = 100 (friction compensation gain corrected to 100%).
Note: Make sure Pn164 and Pn165 are always at the factory settings.

Pn163: Friction compensation factor
During the operation of the equipment, the position deviation is monitored dynamically
and in time by means of the upper computer software oscilloscope. At the same time,
the size of the friction compensation coefficient (Pn163) is gradually changed to check
whether the change in the friction compensation coefficient (Pn163) has improved the
