The Neuron THC Simplicity comes with the following features

Single chip microprocessor based compact control, industrial grade protection, easy to install almost anywhere
Digital display and set arc voltage and other parameters, easy to learn and operate
Works with ALL plasma cutters
Controls Z axis motor driver directly (Pulse/Dir interace, internal motion controller, software 500 uSec PID control loop)
30 cut profiles for different metal thicknesses. Quickly switch between profiles and the ability to quick edit them
Set point voltage range 25 - 250V
Set Point voltage resolution 0.5V
Maximum control accuracy +/- 0.25V
Height control accuracy +/-0.125 mm (.005") using a properly configured Z-axis.
Works in Inches or Millimeters mode
Automatic or manual control of the cutting sequence
"Sample and Hold" mode - THC measures the voltage at the end of the AVC Delay and uses it as a set point for the remainder of the cut
Automatic Collision Avoidance. This safety feature allows the control to automatically adjust the torch height during a cut to help prevent torch crashes
THC OFF hardware input for control from CNC to disable automatic control when corners, end of cut, circle of small radius
Programmable arc voltage limiter Lock Head Down to help prevent torch diving and crashing when crossing a kerf, corners, end of cut
Programmable arc voltage control loop dynamic (gain) value
Works with Float Head and Ohmic sensors for IHS simultaneously (availability of ohmic input depend from controller version PCB)
Shot mode – can use for marking centers of the holes
Improved Jog - the lifter initially jogs 0.25 mm. After 0.5 second, it begins continuous motion at the IHS Speed. After 1.5 seconds, the lifter increases the speed to the programmed Manual Speed
Programmable torch retract delay. This future for example can use for disabling plasma power supply before end of cut (few tens of milliseconds) without motion stop for reducing pierce divots
Built in Testing mode of the cutting sequence
Integrated diagnostic system informs the operator of the errors that occurred
Programmable automatic positioner speed
Programmable jog positioner speed
Programmable IHS (initial height sensing) touch speed
Programmable acceleration
Programmable arc transfer height
Programmable pierce height
Programmable pierce time
Programmable cutting height
Programmable AVC (automatic voltage control) delay time
Programmable crossover (IHS start) height (high-to-low speed transition point)
Programmable torch retract height
Programmable maximum torch slide length (Soft Limit)
Easy setup for Float Head switch offset value
Voltage feedback (divider) - Raw arc voltage divider (houses on the plasma interface board) or 1:20 ( input for Hypertherm cutters)
Easy setup for digital inputs, ability to select ActiveLow/ActiveHi properties for each input
50 kHz maximum step frequency, 50% Duty cycle
Buffered Step & Direction differential outputs for direct interface to Motor Driver
All I/O interface (include arc voltage) are isolated and simple wiring (Cat5e cables and RJ45 connectors)
Control module has a size 115x90x45 mm with DIN mounting standard
