Abnormality in temperature detector
E019 *1)
circuit.
The internal temperature of the
inverter is rising because the rotational
E020 *1)
speed of the cooling fan is reduced and
the cooling is insufficient.
E021 Internal temperature has increased.
Disconnection of the wiring of the main
E024
power supply side has occurred.
E030 Sudden increase of current.
Disconnection of the wiring in the
E034
motor side has occurred.
Abnormal motor temperature.
E035
Thermistor abnormality.
E036 Brake abnormality.
Increase of current during slow speed
E038
operation.
E040 Keypad disconnection error
E041 RS485 communication error
E042 RTC error
E043 to E045
There is an error in the EzSQ program.
E050 to E059
E060 to E089 There is an error in the option.
1:E090 to E093 1:There is an error in the STO path *2)
2:E094 to E097 2:There is an error in the P1-FS. *2)
A disconnection error of the signal line
E100
occurred at P1-FB
The current position has exceeded the
E104 setting range of [AE-52] and [AE-54] in
position control.
The speed deviation exceeded "[bb-83]
E105
Speed deviation error detection level".
Position deviation exceeded "[bb-86]
E106 Position deviation error detection
level".
The speed has exceeded "[bb-80]
E107
Over-speed detection level".
E110 A contactor error has occurred
This error related to the feedback
E112
option
This is an error when starting up PID
E120
function.
*1) As a major failure error, the output terminal function [MJA] turns
ON. And these errors could not be canceled with input terminal
028[RS]. However the E020 error can be reset after the inverter
temperature drops down.
*2) For SH1 series, function safety is invalid.
※For others errors not shown above, contact your supplier
or local Hitachi inverter sales office.
Details
・Carry out counter measures for the inverter noise.
・If it occurs consecutively, there is a possibility of inverter failure.
・If there is any foreign matter, it may be recovered by removing it.
・The cooling fan is reached its lifetime, and it is needed
replacement.
・Lower the carrier frequency.
・Requires a review of the installation circumstances.
・Due to clogging or life of the cooling fan, The cooling fan may
not be operating normally.
・Lower the carrier frequency.
・Check the fastening of the input wiring with screws.
・Check that the 3 phases are correctly inserted.
・Verify if a ground fault or a cable disconnection/rupture has
occurred at the output wiring.(possible short circuit)
・Check that the motor is not locked.
・Check the output wiring disconnection, motor insulation failure,
...etc.
・Check that the 3 phases are correctly connected.
・Improve the motor cooling circumstances.
・Use the overload restriction function.
・Check if the thermistor is damaged.
・Check the thermistor settings.
・Check if the brake is damaged and if the wiring for the [BOK]
signal is disconnected.
・Check the brake waiting time.
・If torque is needed during slow speed, a review of the inverter
capacity is necessary.
・Check for the disconnection of the keypad VOP from the inverter.
・Noise counter-measures are necessary.
・Noise counter-measures are necessary.
・Check the communication setting.
・Battery replacement for the keypad VOP is necessary
・For more information, contact your supplier or local Hitachi
inverter sales office.
・This error related to the feedback option.
For details, contact your supplier or local Hitachi inverter sales
office.
・These are errors related to feedback control.
Review the operating conditions, check the wiring, encoder
settings and other related parameter settings again.
For details, contact your supplier or local Hitachi inverter sales
office.
・Re-check [AF120] to [AF123] and wiring etc. of external
contactor.
・For details, contact your supplier or local Hitachi inverter sales
office.
・Check the wiring and check the parameter settings related to PID
soft start such as [AH-76].
