Hitachi J300U Series instruction manual Other display

Description	Contents			Display
Optional	An error occurs in the optional connection (connector, etc.).		Option 1
connection error
			Option 2
Optional	An error message outputted from the optional PCB	NOTE 5	Option 1
PCB error
			Option 2
Phase failure	When a phase failure is detected on the receiving side {R(L1), S(L2), T(L3)}
protection error	of the inverter, the output is cut off. (NOTE 3)
Power module	The detector which is built in the power module operates.		Constant speed
protection	When the output side of the inverter is shorted or the motor is		Deceleration
	restricted, a large current flows through the inverter and causes a
	fault. Therefore, when a current in the power module or an		Acceleration
	abnormal temperature of the main device is detected and it
			Stop
	exceeds a specified value, the output is cut off.

NOTE 1: If a trip occurs, press the RESET key or short the reset terminal RS-CM1 assigned as a control circuit terminal after a delay of 10 seconds.

NOTE 2: A trip can be cleared by pressing the RESET key or shorting the reset terminal RS-CM1 assigned

as a control circuit terminal. Resetting the power supply cannot clear a trip. (To reset the power supply is to turn power off and turn it on again after the CHARGE lamp at the upper right corner of the control PC board goes off.) Check again whether the set data is correct.

NOTE 3: Power OFF during motor deceleration may cause an input phase failure error.

NOTE 4: The instantaneous ride-thru period of 15ms may be shortend depending on the power supply voltage or load.

NOTE 5: When the J-FB is installed, an error is displayed for each factor as shown below. Encoder line break:

Overspeed:

Positioning error:

Thermistor line break: Motor overheat:

Malfunction or banormality on built-in CPU of the option:

	_	_ _	It is displayed when the reset signal is kept supplied or an error occurs between the digital operator
			and inverter. When one of the keys		,		, and FUNC is pressed, it is recovered.

When it is not recovered, turn power on once again.

	_ _	It is displayed when a data set value more than 3 digits in length (for example,		1000) is set.
_	_ _	It is displayed when power is turned off.
_	_ _	There is no trip history available.
		This is not an abnormal operation because the instantaneous stop restart function is being performed.
		(When 1 to 3 is selected by the extension function	.)
_	_	The autotuning operation terminates normally.
_	_	The autotuning operation terminates abnormally.
_	_	Waiting due to insufficient voltage. After recovery, the original display appears.
