• Software setting
1. Slightly reduce the value of parameter Sensitivity.
2. Slightly increase the values of parameters In Position Tolerance and
Zero Limit Speed Range.
Note: Please be careful. Because these operations may lead to lower precision of follow-up and
cutting separately.
4.4.3 The Capacitance is not 0 when the Cutting Head Touches the
Workpiece / The Cutting Head Keeps Moving Downward during
Calibration
Cause
• The workpiece and the machine tool are not connected or not well connected.
• Insulator like rust and paint exists on the calibrating position of the workpiece.
Solution
1. Manually move the cutting head downward with small step size like 0.1 until it
touches the workpiece, and check current capacitance.
2. Set the value of parameter Touch Part Capacitance greater than current
capacitance.
4.4.4 The Actual Follow-up Height is Different from the Calibrated Follow-
up Height
Cause
Enormous change of the environment temperature causes the deviation of the
calibration curve.
Solution
Calibrate the distance again.
See Commissioning Steps for details.
4.4.5 The Cutting Head Frequently Stops Working while the Capacitance
Feedback is Normal, the Calibration Result is Well and No Alarm Occurs
Cause
The external force caused by gas that flows through the cutting head leads to poor
connection between the contact inside the ceramic ring and the cutting head signal
port, and then an alarm of touching workpiece occurs. As a result, the cutting head
stops working even though the nozzle does not touch the workpiece during cutting.
