4.4.6 The Cutting Head Shakes Substantially during Cutting a Thin Sheet
Cause
The air pressure is high.
Solution
Set parameter Sensitivity as 2 (default value: 5) and parameter In Position
Tolerance as 0.2 (default value: 0.1).
4.4.7 An Alarm Follow-up Process at Error Status Occurs when Z-axis
Moves in Jog Mode or the Follow-up is Turned on Manually
Cause
• The axis direction of the drive is incorrect and outside interference leads to
zero drift.
• Outside interference leads to zero drift.
Solution
Do the following (taking a Panasonic A6 series servo drive as an example):
1. To judge whether the axis direction of the drive is correct and solve the
problem, do the following:
1. Click Z+ / Z- in the software and see whether the cutting head moves:
• If it does, it indicates the direction is correct.
• If it does not, it indicates that the direction is incorrect. Proceed
to next step.
2. Optional: Modify the value of parameter Axis Direction and restart the
drive.
2. To adjust zero drift, do the following:
1. Ensure the value of parameter Pr3.15 is the default value 0.
2. Turn on the drive, and automatically adjust zero drift AF_oF1, AF_oF2
and AF_oF3.
Turning on the software is not required in this step.
