assembly quality. If the two curves are very different, it is suggested to replace ball screw.
Uni-directional pitchcompensation(only fill in positive table)
Regardless of moving direction, controller will always send compensation values in the pitch table at
the same point of the stroke.
Axial stroke is in the positive direction of home: Moves the axis away from home toward the
positive direction of machine coordinate, measures the pitch error and enters the error into the "pos"
row of the pitch table. Note that the fill in pitch table no. in increasing order.
Axial stroke is in the negative direction of home: Moves the axis away from home toward the
negative direction of machine coordinate, measures the pitch error and enters the error into the
"pos" row of the pitch table". Note that the fill in pitch table no. in decreasing order.
Bi-directional pitch compensation(fill in positive & negativetable)
According to the moving direction of machine, controller will determine to use positive or negative
table value at the same point of stroke.
Axial stroke is in the positive direction of home:Moves the axis away from home toward positive
direction of machine coordinate, measures the pitch error and enters the error into "pos" row of the
pitch table". Revert the axis toward home, measures the pitch error and enters the error into "neg"
