Adjustments
6.8.2 Friction Compensation
Friction compensation rectifies the viscous friction change and regular load change.
The factors causing load changes include grease viscosity resistance changes resulting from temperature
changes in addition to viscous friction and regular load changes resulting from equipment variations and secu-
lar changes.
Friction compensation is automatically adjusted by the following settings.
1. The advanced autotuning level is set to mode 2 or 3.
2. The one-parameter tuning mode is set to 2 or 3.
Refer to the following description and make adjustments only if manual adjustment is required.
