Page 357 Appendix 8 Stored Pitch Error Compensation Function Note: The data in “( )” is the measured result is incremental value, i.e. positive error indicates excessive movement, and negative error indicates insufficient movement. Compensation point 0 corresponds to the reference point ;compensation point 1 corresponds to the one after the reference point moveing 10000μm along the positive direction;...

Page 360 GSK983Ma Milling Machine Center CNC System User Manual The compensation value is +3（-5）when the tool moves along the “+” direction and reaches the compensation point. The compensation value is +3（-5）when the tool moves along the “-” direction and reaches the compensation point.
Page 361 Appendix 8 Stored Pitch Error Compensation Function Limitation: (Valid pitch error compensation value) × (pitch error compensation magnification) ×CMR The result should be within the range ±127. Otherwise, the compensation will be performed incorrectly. In some case, if a value exceeding ±127 is needed, the exceeding part can be divided and added to the adjacent point for compensation.
