3 – Torch Height Control Axis Setup
Retry on Transfer Fail: Retry on Transfer Fail: When IHS completes, the torch attempts ignition, the CNC starts a 10
second timer, waits for the Cut/Mark Sense input (or Cut Sense # input) to turn on, and displays the status
message Waiting For Arc On, If the input does not activate within 10 seconds, the ignition process stops,
the torch retracts, and the IHS starts again with another attempt to ignite the torch. The CNC repeats this
sequence twice.
Options: Yes, No
Slide Length: Enter the physical length of the slide.
Recommended setting: Sensor THC: 321.31 mm (12.65 inches)
Home: Select the homing method for the THC Axis. If the Home to Switch option is selected, the CNC Nozzle Contact
Sense input is the Home Switch input.
If you select the Hard Stop Current Limited option, the THC Torque Limit output should be connected to the
current limit input of the amplifier to reduce torque during homing or initial height sense. Select the option
that corresponds to the installed lifter and motor drive.
Options: Hard Stop, Hard Stop Current Limited, Home Switch
Recommended Setting: Sensor THC: Hard Stop Current Limited.
Home settings for current-type drives
Current Limit%: Set the maximum current output for the operation of the lifter motor.
Range: 0.001 to 100; Default: 50
Home Current Limit%: Enter the maximum current during the homing sequence to stall and detect the top of the slide.
Set Homing Current Limit to 50% of drive capacity.
Range: 0.001 to 100; Default: 10
IHS Current Limit%: Set the maximum current during IHS to stall and detect the workpiece.
Range: 0.001 to 100; Default: 5
Tracking Mode
The CNC uses voltage tracking to lock on to the actual arc voltage and compare it to the Set Arc Voltage.
You can choose individual tracking mode settings for Plasma 1, Plasma 2, Marker 1, Marker 2, and Laser
processes.
Normal: For most applications, set tracking mode to Normal. Voltage tracking in Normal mode locks on
within 2 volts of the Set Arc Voltage value. Adjust voltage gain to increase lifter responsiveness. In Normal
mode, arc voltage accuracy is +/- 1.0 arc volt.
Average Voltage Over: Sets the arc voltage sampling rate. Phoenix records the arc voltage every
millisecond and averages the arc voltage over the number of milliseconds entered. The average value is
compared to the voltage set point and then the command to the lifter is calculated.
