2. Observe the corresponding step length change of Z-axis coordinate and
make a distinct between the increase and decrease of the changing
value.
• If Z-axis coordinate change is different from the specified step
length, it indicates that the parameter is wrong and you should
modify it. See PG Frequency Dividing Ratio is Set Incorrectly for
details.
• If Z-axis coordinate change is the same with the specified step
length, it indicates that the parameter is correct.
4. Check and confirm that there is no alarm and Current Capacitance shows in
the software.
5. Check and confirm that Z-axis direction is adjusted correctly.
See Adjust the Axis Direction for details.
6. To ensure basic motion and coordinate display are correct, and Z-axis can
return to the machine origin, check system parameters in the software.
4.2.2 Detect Capacitance
This operation is used to observe the capacitance and check its stability.
To detect capacitance, do the following:
1. Move the cutting head to the workpiece and check whether current capacitance
changes in real time.
When the cutting head touches the workpiece, the capacitance should be zero.
If it is not zero, see The Capacitance is not 0 when the Cutting Head Touches the
Workpiece/The Cutting Head Keeps Moving Downward during Calibration for
details.
2. Set parameter Z Up Position. See Parameters Setting Area for details.
3. To check whether the current capacitance is stable, do the following:
1. Move the cutting head to the position 30mm far from the workpiece
surface and keep it still.
2. Observe whether the change of the current capacitance is within 30Hz:
• If it is, it indicates that the current capacitance is stable.
• If it is not and the last three numbers of the current capacitance
change obviously, it indicates that the electric interference is
serious.
