E.09 Low Input Power Error
Reason: The PHC input power is 20% below the nominal voltage.
Solution: increase the input voltage to within the nominal operating range.
E.10 High Input Voltage Error
Reason: The PHC input power is 15% above the nominal voltage.
Solution: Decrease the input voltage to within the nominal operating range.
E.11 Over-Temperature Error
Reason: The motor drive circuitry has experienced an over-temperature shutdown.
Solution: Allow the unit to cool down.
E.12 Interlock Tripped Error
Reason: The External Interlock has been tripped.
Solution: Verify that there is a contact closure across the External Interlock input on the CNC Interface
connector.
E.13 Excess Plate Contact Error
Reason: The torch tip made excess contact with the plate during a short period of time.
• The voltage set point is too low.
• The consumables are worn and the voltage set point needs to be increased.
Solution: The next CYCLE_START resets this error.
E.99 Internal Software Error
Reason: An abnormal, unexpected condition occurred in the software.
Solution: Perform a power up reset of the PHC.
