Hitachi L300IP Error Status Codes and Error Trip Conditions

Error	Name	Probable Cause(s)
Code
E21	Inverter thermal trip	• Inverter internal temperature is above
		the threshold
E23	Gate array error	• An internal inverter error has occurred
		(CPU / gate array IC)
E24	Phase failure detection	• One of three lines of the 3-phase
		power is missing
E30	IGBT error	• Instantaneous over-current on any
		IGBT (output transistor) device
E35	Thermistor	• Thermistor input, [TH] and [CM1], is
		over the temp. threshold
––––	Under-voltage (brownout)	• Low input voltage caused the inverter
	with output shutoff	to turn OFF the motor output and try to
		restart. If unsuccessful, a trip occurs.
	Automatic restart and phase	• Inverter is restarting, due to an over-
	loss	current, over-voltage, under-voltage, or
		a phase loss event.
E6x	Expansion card #1 error	• An error has occurred in an
		expansion card or at its connecting
		terminals. Please refer to the manual for
E7x	Expansion card #2 error
		the expansion card for additional details.

Error Status Codes and Error Trip Conditions

The digit to the right of the decimal point in the error code (such as E01.4) indicates inverter status at the moment the error occurred. Use the Up and Down arrow keys to scroll through the trip condition parameters.
