USER MANUAL
1. Operator runs the work program by click on the “START” button on the UCCNC.
2. The UCCNC CNC control move torch (x/y) to the IHS start position and wait the Motion
signal from the controller. “RUN” indicator on the Neuron control panel is flash.
3. Operator turn ON the “Cutting Start” switch on the operator panel.
4. The torch travels towards the plate at Automatic speed and switches to the IHS Speed
when the crossover IHS Height is reached. The torch touches the plate at the IHS Speed.
5. The torch immediately retracts to the Arc Transfer Height.
6. Plasma Start signal is issued to the power supply.
7. The power supply initiates an arc and the Neuron.THC receives a Transfer signal from the
power supply.
8. The torch moves to the Pierce Height and the Pierce Time timer is initiated.
9. When the Pierce Time elapses, the torch moves to the Cut Height.
10. The Neuron.THC issues a Motion signal to the x/y machine.
11. The x/y machine begins profiling the part.
12. The AVC Delay timer is initiated.
13. AVC Delay time starts. If sample mode enabled THC is sampling the arc voltage, at end of
AVC Delay or after removing the Hold signal from CNC. THC uses the last stable sampled
voltage as a reference to control height for rest of cut. If sample mode is disabled THC
uses the Set Arc voltage as a reference to control height.
14. When AVC Delay elapsed, the THC start closed loop height control.
15. The programmed Arc Voltage, thus the torch height, can be increased and decreased while
in AVC ON by rotating the encoder on the operator’s panel or click on the target voltage
DRO on the UCCNC control panel and mouse wheel. AVC mode is disabled, thus freezing
the torch height, any time a Hold signal is received (from G-Code).
16. If AVC is disabled (AVC OFF) the torch height, can be increased and decreased by rotating
the encoder on the operator’s panel or click on the Position DRO on the UCCNC control
panel and mouse wheel.
17. If Head Safety Lock is enabled, AVC mode is disabled any time a sudden increase in arc
voltage is sensed, such as when crossing a kerf or running off the plate.
18. If collision avoidance is enabled, the arc voltage is automatically increased any time
contact is sensed between the torch and the plate, provided that the Ohmic function is
enabled. If the torch contacts the plate while a Corner signal is applied, the torch retracts
to the programmed Cut Height
19. When the Cycle Start signal is removed from the Neuron.THC, the torch retracts to the Full
Raise or Partial Raise Height depending on the Partial/Full setting.
Requirements and Check List for first Start-up
After the Neuron.THC system is installed, perform the following setup sequence to
ensure proper operation.
1. Open the settings window by clicking “NEURON” button on the control panel.
2. Move to the tab «Engine Settings» and click on the «Change Settings» button. It opens
Motion control configuration.
3. Set parameters of the motor driver «pulses in unit» (numbers of pulses in the 1 mm).
4. To apply changing click on the “Save Settings” and then “Hardware Reset” for restarting
the controller. Restart UCCNC.
5. Click on the “NEURON” button after restarting and select the tab “Diagnostics”.
6. Check the Homing, Float Head, Ohmic sensors inputs, “Cutting Start” switch input. If
sensor is activated you will see green indicator on the “check inputs” field. You can select
type of the sensor and inputs signals N.O. or N.C.
7. In IDLE mode state of the all sensor are off and all indicators are gray.
8. Turn on motor driver power supply. Clicking the buttons torch “UP/DOWN” on the control
panel or operator control module, make sure that torch moving in the correct direction. If
not – set “Reverse Engine” checkbox on the Motion control group.
9. Click button. System will be starting the homing procedure.
