Friction Torque Compensation Function
Outline of Operation
As a function to reduce the effect of friction, you can set the unbalanced load compensation
that always compensates the constantly working offset torque, and the dynamic friction
compensation that changes its direction depending on the operating direction.
You can use the function under the following conditions:
 When Servo is ON
 When there is no trouble with the motor's normal rotation

Pn608
Forward Direction Torque 
Offset
Set the dynamic friction compensation value that is 
added to the torque command when a forward 
direction position command is input for position 
control or fully-closed control.

Pn609
Reverse Direction Torque 
Offset
Set the dynamic friction compensation value that is 
added to the torque command when a reverse 
direction position command is input for position 
control or fully-closed control.
