3 – Torch Height Control Axis Setup
Recommended settings: Sensor THC: Choose Plasma 1 or 2 as the process, then choose Normal for
tracking mode. Do not adjust voltage gain, and set Average Voltage Over to 25 ms. Do not use Special
tracking mode with the Sensor THC.
HyIntensity ® Fiber Laser: Choose Laser as the process, choose Normal for tracking mode, set Average
Voltage Over to 1 ms, and set Corrections Made Every to 10 msec.
Special tracking mode
Use Special tracking mode only for applications that require an extra high-speed, high-accuracy response,
such as diamond-plate cutting. In Special mode, arc voltage accuracy is +/- 0.25 volt.
Options: Normal, Special. The voltage gain range for Normal mode is 0 to 500 volts; the recommended
value is 100 volts. The voltage gain range for Special mode is 0 to 10; the recommended value is 10.
Range: 1 to 100
Lock on Delta Limit: Creates a lock-on window above and below the lock-on value. The set arc voltage
value, within this window, controls the operation of the THC. Enter the number of volts above and below the
lock-on value to create the lock-on window.
Range: 0 to 10 volts; Default: 0
Lock on Rate Limit (for Special Tracking Mode): Sets the number of consecutive values within the
lock-on window that are required to define lock-on. Enter the number of consecutive values within the
lock-on window that must be recorded to remain at lock-on.
Range: 0 to 10 volts; Default: 10
Voltage Tracking Range: Sets the allowable variation in arc voltage from the set point. If the arc voltage
exceeds this range, the CNC faults and pauses cutting. Enter the number of volts of allowable arc variation.
Range: 5 to 400 volts; Default: 20
Sensor THC I/O points
Following are typical I/O points assigned in the Machine Setups > I/O screen for Sensor THC.
THC Torque Limit: This output connects to the input /P-CL and /N-CL on the Yazkawa drive. This output limits the
motor torque during IHS when using stall force, and during homing. The CNC turns this output off during
cutting.
Nozzle Contact Enable: This output activates during the initial height sense and remains on while cutting when Nozzle
Contact Cutting is set to ON in the Process screen.
Nozzle Contact Sense: This input activates during initial height sense when the torch detects the workpiece and
Nozzle Contact IHS is set to ON in the Process screen. Nozzle Contact Sense is also used as a homing
input signal.
 Nozzle Contact Enable and Nozzle Contact Sense are automatically assigned when the
CNC supports the analog input board for the THC ports. You can select these I/O in the
Watch Window, and the CNC displays them in the Analog Diagnostics screen. You
cannot change their assignments.
