-Friction Compensation
This function compensates for changes in the following conditions.
- Changes in the viscous resistance of the lubricant, such as the grease, on the sliding
parts of the machine
- Changes in the friction resistance resulting from variations in the machine assembly
- Changes in the friction resistance due to aging
The conditions for applying friction compensation depend on the mode. The friction
compensation setting in Pn408.3 applies when the Mode is 1. The friction compensation
function is always enabled regardless of the friction compensation setting in Pn408.3
when the Mode is 2 or 3.

- Feedforward
If Pn140 is set to the factory setting and the mode setting is changed to 2 or 3, the
feedforward gain (Pn109), speed feedforward (VFF) input, and torque feedforward
(TFF) input will be disabled.
Set Pn140.3 to 1 if model following control is used together with the speed feedforward
(VFF) input and torque feedforward (TFF) input from the PC or PLC...etc.

• Model following control is used to make optimum feedforward settings in the
DRIVER when model following control is used with the feedforward function.
Therefore, model following control is not normally used together with either the
speed feedforward (VFF) input or torque feedforward (TFF) input from the PC or
PLC...etc. However, model following control can be used with the speed
feedforward (VFF) input or torque feedforward (TFF) input if required. An
improper feedforward input may result in over- shooting.
