Hitachi hitachi series inverter

Error

Code Name Cause(s)

E25 Main circuit

error (*3)

The inverter will trip if the power supply establishment is

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 W hen 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

E59

EzSQ user trip (0 to 9) When user –defined trip happens, inverter trips and

displays the error code.

E60 Option error (DeviceNet

Communications error)

If the disconnection due to the Bus-Off signal or timeout

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

E68

Option error The inverter detects errors in the option board mounted in

the optional slot. For details, refer to the instruction

manual for the mounted option board.

E69 Option error (inverter communication

error)

If timeout occurs during the communication between the

inverter and DeviceNet option board, the inverter will shut

off its output and display the error code shown on the

right.

E80 Encoder

disconnection

If the encoder wiring is disconnected, an encoder

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.
