Hitachi L300IP Error Codes, Basic Error Codes

Error Codes

The L300P series inverters will trip on over-current, over-voltage, and under-voltage to protect the inverter. The motor output turns OFF, allowing the motor to free-run to a stop. Press the Stop/Reset key to reset the inverter and clear the error.

Basic Error Codes

Error	Name		Probable Cause(s)
Code
E01	Over current event while at	•	Inverter output was short-circuited
	constant speed	• Motor shaft is locked
		• Load is too heavy
E02	Over current event during
		• A dual-voltage motor is wired
	deceleration	incorrectly
		Note: The L300P will over current trip
E03	Over current event during
		at nominally 200% of rated current
	acceleration
E04	Over current event for other	• DC braking power(A054) set too high
	conditions	•	Current transformer / noise error
E05	Overload protection	• Motor overload is detected by the
		electronic thermal function
E06	Braking resistor overload	•	Regenerative braking resistor exceeds
		the usage time or usage ratio
E07	Over voltage	• DC bus voltage exceeds a threshold,
	protection	due to regenerative energy from motor
E08	EEPROM error	• Built-in EEPROM memory experi-
		enced noise, high temperature, etc.
E09	Under-voltage error	• DC bus voltage decreased enough to
		cause a control circuit fault
E10	CT error	•	High electrical noise near inverter
	(current transformer)	•	A fault occurred in the built-in CT
E11	CPU error	• Built-in CPU had internal error
E12	External trip	•	[EXT] input signal detected
E13	USP (Unattended Start	• When (USP) was enabled, an error
	Protection)	occurred when power was applied while
		a Run signal was present
E14	Ground fault	• A ground fault was detected between
		the inverter output and the motor. This
		feature protects the inverter, and does
		not protect humans.
E15	Input over-voltage	•	Input voltage was higher than the
		specified value, 60 sec. after powerup
E16	Instantaneous power failure	• Input power removal > 15ms or
		> B002... inverter restarts on Run cmd
