Hyundai Generator Fault Codes, Troubleshooting and Maintenance

 

 

 

Error Code	Name	Probable Cause(s)
E05	Overload protection	When a motor overload is detected by the electronic thermal function, the inverter trips and turns OFF its output.
E06	Braking resistor overload	When the regenerative braking resistor exceeds the usage time allowance or usage ratio, the inverter trips and turns OFF its output to the motor.
E07	Over voltage protection	When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor.
E08	EEPROM error	When the built-in EEPROM memory has problems due to noise or excessive temperature, the inverter trips and turns OFF its output to the motor.
E09	Under-voltage error	A decrease of internal DC bus voltage below a threshold results in a control circuit fault. This condition can also generate excessive motor heat or cause low torque. The inverter trips and turns OFF its output.
E10	CT (current transformer) error	If a strong source of electrical interference is close to the inverter or a fault occurs in a built-in CT (current transformer), the inverter trips and turns its output OFF.
E11	CPU error	A malfunction in the built-in CPU has occurred, so the inverter trips and turns OFF its output to the motor.
E12	External trip	A signal on an intelligent input terminal config- ured as EXT has occurred. The inverter trips and turns OFF the output to the motor.
E13	USP	When the Unattended Start Protection (USP) is enabled, an error occurred when power is applied while a Run signal is present. The inverter trips and does not go into Run Mode until the error is cleared.
E14	Ground fault	The inverter is protected by the detection of ground faults between the inverter output and the motor during powerup tests. This feature protects the inverter, and does not protect humans.
E15	Input over-voltage	When the input voltage is higher than the specified value, it is detected 60 seconds after powerup and the inverter trips and turns OFF its output.
E16	Instantaneous power failure	When the input power is removed for more than 15ms, the inverter trips and the output to the motor turns OFF. If the power failure duration exceeds the duration set in parameter B002, it is consid- ered a power failure. When input power is restored, the inverter restarts if the Run signal is present, depending on the restart condition.
E21	Inverter thermal trip	When the inverter internal temperature is above the threshold, the thermal sensor in the inverter module detects the excessive temperature of the power devices and trips, turning the inverter output OFF.

Error Code	Name	Probable Cause(s)
E23	Gate array error	An internal inverter error has occurred in commu- nications between the CPU and gate array IC.
E24	Phase failure detection	One of three lines of the 3-phase power is missing.
E30	IGBT error	When an instantaneous over-current condition occurs on any IGBT (output transistor) device, the inverter alarm trips. then it turns the outputs OFF in order to protect the circuitry.
E35	Thermistor	When a thermistor is connected to terminals [THM] and [CM1] and the inverter has sensed the temperature is too high, the inverter trips and turns OFF the output.
E36	Brake error	When the inverter releases the brake and cannot detect whether the external brake is ON or OFF within the waiting time (set by parameter B024), the inverter trips and turns OFF the output to the motor.
––––	Under-voltage (brownout) with output shutoff	Due to low input voltage, the inverter turns its output OFF and tries to restart. If it fails to restart, then the alarm trips to record the under-voltage error event.
E6X	Expansion card #1 connection error	An error has occurred in an expansion card or at its connecting terminals. Please refer to the manual for the expansion card for additional details.
E7X	Expansion card #2 connection error

 

NOTE: If an EEPROM error (E08) occurs, be sure to confirm the parameter data values are still correct.
