Automatically establishes the SetPoint based on the cutting height that is set.
Is the target voltage to be achieved.
Limit from 40 to 400VDC, True Voltage measured for the plasma.
Is the tolerance or (+/-) voltage range used to generate an adjustment. The torch height is not commanded to adjust if the true voltage is within side the specified range. It can be between 2 to 32VDC
Test Mode is to simulate the signals coming from the THC unit. This can be used to test the wiring and configuration to make the unit can read the signals sent.
Torch motion starts the number of seconds you set as DT after the ARC signal is determined. This can be a value between 0.1 to 9.9 seconds.
This is the divider ratio matching the one set in the plasma power supply. This can be a value between 1 to 60.
This data smoothes the voltage reading. This can be a value between 0 to 3.
value of the off load voltage detection in the plasma cutter - used to detect the main (cutting) arc: 50- 300V by default: 200V.
when enabled : activate output 10 (to enable PTS)
when disabled : disable output 10 (to disable PTS)
Set the OFF SET_Z
Q – Set the Height parameter
