3 Operation Example
The friction torque compensation is applied according to the operation as shown in the drawing below.
Note The dynamic friction compensation holds the compensation value until the command direction changes, in
order to sustain the position during stabilization.
By setting the torque command value in
Unbalanced Load Compensation
(3310-02 hex), you can
reduce the variations of positioning operations that occur depending on the movement directions. This
object is useful when a constant amount of unbalanced load torque is always applied to the Servomotor
at axes such as a vertical axis.
By setting the friction torque for each rotation direction in
Positive Dynamic Friction Compensation
(3310-03 hex) and
Negative Dynamic Friction Compensation
(3310-04 hex), you can reduce deteri-
oration of and inconsistencies in the positioning stabilization time due to dynamic friction. These objects
are useful for loads that require a larger amount of dynamic friction torque for a radial load, such as the
belt-driven shaft.
