Quadrant Projection Suppression Function
Outline
Control configuration can be switched to suppress quadrant projection occurring during
arc interpolation of 2 or more axes. To be used in conjunction with load fluctuation sup
-
pression function.
Applicable range
This function can be applicable only when the following conditions are satisfied.
Conditions under which the Hybrid vibration damping function is activated
Control mode
• Should be position control mode
Others
• Should be in servo-on condition
• Elements other than control parameters, such as prohibition of deviation
counter clear command input and torque limit, etc. are set appropriately,
in a state where there are no obstructions in normal motor revolutions.
Caution
There are cases where effects cannot be observed under the following conditions.
Conditions which obstruct disturbance observer action
Load
• When rigidity is low (anti-resonance point exists in the low frequency
range of 10 Hz or lower).
• When non-linearity of load is strong from existence of backlash, etc.
• When action patterns are changed.
Related Parameter
Class No.
