4.2.3 Calibrate Servo
This operation is used to eliminate the zero drift of servo motor caused by velocity
loop control.
To judge zero drift, do the following:
1. Turn on the servo motor and enable servo in the software.
2. Observe the display interface of the servo drive. If the value changes greatly, it
indicates large outside interference. Proceed to next step.
3. Optional: Observe the coupling at the joint of Z-axis motor and screw. You can
find that the coupling rotates slightly.
To calibrate servo, do the following:
1. To move the cutting head to the middle of the stroke range and avoid the
cutting head exceeding the stroke, click X+/X-/Y+/Y- in manual control area.
2. Click . The system automatically generates the value of parameter Servo
Compensation Parameter.
The cutting head slightly moves back and forth to compensate the error caused by
zero drift.
4.2.4 Calibrate Capacitance
This operation is used to measure the corresponding distance between capacitance
and position between the cutting head and the workpiece.
Before calibrating capacitance, do the following:
• To decide the workpiece type for calibration, set parameter Nonmetal Mark.
• Ensure the capacitance is stable.
To calibrate capacitance, do the following:
1. Move the cutting head to the position about 5mm far from the workpiece
surface, and keep the workpiece still all the time.
2. Click . The system starts to calibrate capacitance for 20s.
During calibrating capacitance, the cutting head does the following:
1. Move downward slowly to detect and touch the workpiece.
2. Move upward 5mm after it touches the workpiece.
3. Move downward slowly to detect and touch the workpiece again.
