What to do if Watch Dog Timeout FAIL appears on Hypertherm Command THC Cutter?
If the 'Watch Dog Timeout FAIL' error appears, it means a processor on the THC control PCB has failed. In this case, you should call Hypertherm Technical Service for assistance.
What to do if Hypertherm Command THC shows Motion FAIL?
If the Hypertherm Cutter shows a 'Motion FAIL' error, it indicates the torch didn't reach the Home position during full retract. Here’s what you can do: * First, verify that the torch isn't blocked from moving. * Second, check for an encoder problem. * Third, place the THC in Manual Position Mode and jog the torch to the Home position to activate the switch. On the THC control PCB, Motor Drive Interface, D49 should illuminate, and when you jog the torch down to deactivate the switch, D49 should extinguish. * Finally, check the Home Limit switch and cable, and replace them if needed.
Why does Hypertherm Cutter display Motor Current Fault?
The 'Motor Current Fault' error on the Hypertherm Cutter indicates that the cable isn't installed or an external interlock isn't satisfied. To resolve this: * Install the cable, ensuring that D51 illuminates on the THC control PCB, Motor Drive Interface. * Also, on the THC control PCB, Ext Interlock Ok, D16 should be illuminated. If it's not, jumper the machine interface cable at the CNC at pins 16 and 35 on plug J6.
What to do if Hypertherm Cutter displays Machine Cable Missing?
If the Hypertherm Cutter displays 'Machine Cable Missing', it means the cable isn't installed or an external interlock isn't satisfied. Here's how to fix it: * Install the cable, ensuring that D15 illuminates on the THC control PCB, Machine Interface Inputs. * Also, on the THC control PCB, Ext Interlock Ok, D16 should be illuminated. If it's not, jumper the machine interface cable at the CNC at pins 3 and 22 on plug J6.
How to resolve 'Torch is in HOME LIMIT' error on Hypertherm Command THC Cutter?
If the Hypertherm Cutter displays 'Torch is in HOME LIMIT', it means the torch retracted to the Home Limit during IHS. To resolve this: * Reposition the lifter, torch, or workpiece. * Adjust the Stall Force and IHS speed, trying a lower speed or a higher stall force. * Select Diagnostic Screen B by pressing on the keypad, then press to start tests. Check that “Upper Limit Switch” indicates “Ok” and “Lifter Type” indicates 2 (X-Y lifter). * Place the THC in Manual Position Mode and jog the torch to the Home position to activate the switch. On the THC control PCB, Motor Drive Interface, D49 should illuminate. Jog the torch down to deactivate the switch, and D49 should extinguish. * Check the Home Limit switch and cable, and replace them if required.
What causes 'Plasma Cable Missing' error on Hypertherm Command THC and how to fix it?
The 'Plasma Cable Missing' error on the Hypertherm Cutter indicates the cable isn't installed. To fix this, check the cable connections at both ends, ensuring that D23 illuminates on the THC control PCB, Plasma Interface Inputs.
Why am I getting a 'Nozzle Contact at Home' error on my Hypertherm Cutter?
A 'Nozzle Contact at Home' error on your Hypertherm Cutter means that nozzle contact is being sensed with the lifter at the Home position. To address this: * Check the ohmic contact wire connections at the shield and inside the plasma interface assembly. * Also, check the ohmic contact wire for a short to ground.
What to do if Hypertherm Command THC shows Diag FAIL?
The 'Diag FAIL' error on the Hypertherm Cutter can occur due to several reasons: * If the torch is inhibited from reaching the Home Limit position during the diagnostic test, place the THC in Manual Position Mode and jog the torch to the Home position to activate the switch. On the THC control PCB, Motor Drive Interface, D49 should illuminate. * If the torch is inhibited from reaching the Lower Limit position during the diagnostic test, place the THC in Manual Position Mode and jog the torch to the Home position to activate the switch. On the THC control PCB, Motor Drive Interface, D50 should illuminate. * If the encoder failed during the diagnostic test, repower the THC, check the encoder, and verify that the torch isn't blocked from moving.
What to do if Hypertherm Command THC displays Lifter NOT Installed?
If the Hypertherm Cutter displays 'Lifter NOT Installed', it means the system was powered up with no lifter cable installed. Check that the lifter I/O cable is connected at both ends.
What does 'Cycle Start ON at INIT' mean on Hypertherm Cutter?
The 'Cycle Start ON at INIT' message on the Hypertherm Cutter means that the cycle start is active during THC power up or while exiting Maintenance Mode. Verify that the CNC start up signal is inactive.
