2.3 Calibrate Capacitance
This operation is used to check the corresponding relationship of capacitance and
position between the cutting head and the workpiece, so as to move Z-axis up and
down in real time and ensure the relative distance between the cutting head and the
workpiece is unchanged.
To calibrate capacitance, do the following:
• In position loop control mode, 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 in machine control area.
• In velocity loop control mode, 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. To open Follow-up Control dialog box, do one of the following:
• In drawing toolbar, click .
• In menu bar, click System → Follow Control.
3. To eliminate zero drift caused by velocity loop controlling, click .
The cutting head slightly moves back and forth to compensate the error
caused by zero drift.
4. Click . The system starts to calibrate capacitance for 20s.
