Hitachi hitachi series inverter user manual E37

Error	Name			Cause(s)
Code
E25	Main circuit			The inverter will trip if the power supply establishment is
	error (*3)			not recognized because of a malfunction due to noise or
				damage to the main circuit element.
E30	Driver error			An internal inverter error has occurred at the safety
				protection circuit between the CPU and main driver unit.
				Excessive electrical noise may be the cause. The inverter
				has turned OFF the IGBT module output.
E35	Thermistor		When a thermistor is connected to terminals [5] and [L]
				and the inverter has sensed the temperature is too high,
				the inverter trips and turns OFF the output.
E36	Braking error		When "01" has been specified for the Brake Control
				Enable (b120), the inverter will trip if it cannot receive the
				braking confirmation signal within the
				Brake Wait Time for Confirmation (b124) after the output
				of the brake release signal.
E37	Safe Stop			Safe stop signal is given.
E38	Low-speed overload protection		If overload occurs during the motor operation at a very low
				speed, the inverter will detect the
				overload and shut off the inverter output.
E40	Operator connection		When the connection between inverter and operator
				keypad failed, inverter trips and displays the error code.
E41	Modbus communication error			When “trip” is selected (C076=00) as a behavior in case of
				communication error, inverter trips when timeout happens.
E43	EzSQ invalid instruction		The program stored in inverter memory has been
				destroyed, or the PRG terminal was turned on without a
				program downloaded to the inverter.
E44	EzSQ nesting count error			Subroutines, if-statement, or for-next loop are nested in
				more than eight layers
E45	EzSQ instruction error			Inverter found the command which cannot be executed.
E50	EzSQ user trip (0 to 9)		When user –defined trip happens, inverter trips and
to				displays the error code.
E59
E60	Option error (DeviceNet			If the disconnection due to the Bus-Off signal or timeout
	Communications error)			occurs during the operation using DeviceNet commands,
				the inverter will shut off its output and display the error
				code shown on the right.
				(The inverter will trip according to the settings of "P045"
				and "P048".)
E61	Option error (duplicated MACID)			If two or more devices having the same
				MAC ID are detected in the same network, the inverter will
				display the error code shown on the right.
E62	Option error (External trip)			If the Force Fault/Trip bit of Attribute 17 in the Instance 1
				of the Control Supervisory object is set to "1", the inverter
				will shut off its output and display the error code shown on
				the right.
E63	Option error			The inverter detects errors in the option board mounted in
to				the optional slot. For details, refer to the instruction
				manual for the mounted option board.
E68
E69	Option error (inverter communication			If timeout occurs during the communication between the
	error)			inverter and DeviceNet option board, the inverter will shut
				off its output and display the error code shown on the
				right.
E80	Encoder			If the encoder wiring is disconnected, an encoder
	disconnection			connection error is detected, the encoder fails, or an
				encoder that does not support line driver output is used,
				the inverter will shut off its output and display the error
				code shown on the right.
