8.0 Connecting the plasma source
ATTENTION : The plasma source generates very high interference and
voltages dangerous to health and life. Incorrect connection will irreversibly
damage electronic components. The connection should be made by a qualified
person. The voltage generated by HF/HV cutters exceeds 10,000V AC and the
Blow-Back 200V DC. Poor contact between the clamp terminal and the material
can irreparably damage the electronics.
A plasma interface is used to control the plasma source and to read
the arc voltage, which isolates and protects the operator and the entire
control system ( including the computer ) from dangerous voltages, as well
as filtering out interference generated by the plasma arc.
8.1 Connecting the interface
The plasma module is powered from the controller's connector ( 24V
DC ) and transmission between the modules takes place via the RS485
bus. The connection must be made with a four-wire shielded cable no
longer than 10m. The shield must be connected to the minus terminal on
the CNC CONTROLLER side. A ground connection is required to
eliminate surges and interference.
After activation of the plasma interface in the software, the
correctness of the transmission between the modules is tested and, if
correct, the blue control LEDs on both modules blink steadily for up to 1s
( 0.5s on, 0.5s off).
In the event of transmission problems, the lights blink in short flashes
every 3s. And an RS485 communication error is displayed in the software.
