LNC-M600
Machine Adjustment
• Rigid Tapping Machine Adjustment Procedure
1. Please increase the maximum allowable following error of Z axis direction (Para. #
1058 is approximately set to 3000). Also increase the maximum servo error of the
spindle (Para. # 1075 is approximately set to encoder size per rotation of the
spindle*10) in order to prevent warning when doing machine adjustment.
2. Confirm Spindle Rotational Direction(Para. # 1071)
Executing the following program:
M29S500
G91G84R-10Z-50F500
M28
M30
Check whether or not the spindle rotational direction is the same direction as M3
direction under non-rigid tapping mode. If not the same, please set Para. # 1071 to 1.
3. Acc/Deceleration Time Adjustment
To adjust acc/deceleration time (parameter 1059) and execute the following program:
M29S2500 ; rotational speed setting is the maximum rigid tapping speed.
G91G84R-10Z-50F2500
M28
M30
During executing, must make the spindle drive device’s current lower than the
saturation value, and make the spindle to turn smoothly.
Please pay attention to whether or not the needed maximum rotational speed can be
reached at the upper enter frequency limit of the spindle. Using Toshiba as an example,
adjust Para. # 373, 425, 426, 427, and 428.
If the spindle rotational speed is not smooth in high rotational speed, please refer to
Para. # 371.
