4.4.1 Serious Electric Interference
Reason

The position of the servo drive creates some interference.

The shielding layer has been damaged or entangled on the external iron frame.

There is no conductivity between the No.4 pin of the M16 three-core aviation plug
towline cable and the amplifier.

There is gap between the follow-up amplifier and the machine.

The RF cable is damaged.

The machine is poorly grounded.
Solution

Ensure that the servo drive, Lambda 5E controller, and EX33A extension terminal
board are grounded properly.
If there is poor contact, construct paling again.

Ensure that the cable shielding layer is intact.
If not, replace the shielding layer.

Ensure conductivity between the No.4 pin of the M16 three-core aviation plug
towline cable and the amplifier.
If not, replace the cable.

Ensure that the follow-up amplifier is entirely in close contact with the machine.
If not, before installing the amplifier, use a piece of abrasive paper to remove the
oxidized layer from the contact surface.

Use a multimeter to check the RF cable.
If the RF cable is not working, replace it.

Ensure that the machine is grounded properly.
4.4.2 Capacitance is Not Zero when Touching the Material
Reason

There is no conductivity or the conductivity is poor between the material and
machine.

The material has insulative objects such as rusts or paint in the calibration area.
Solution
Follow the steps below to help troubleshoot:
1. In Step mode, slowly lower the cutter to make it touch the material and check the
capacitance again.
2. Set Touch Part Capacitance to a value larger than the capacitance currently
displayed.
4.4.3 Cutter Continues Lowering After Touching the Material During Calibration
Reason
After the cutter nozzle touches the material, the system receives no signal from the follow-
up amplifier that indicates zero capacitance.
Solution
See Capacitance is Not Zero when Touching the Material.
4.4.4 Actual Follow Height Differs from Setting
Reason
