| Name | Cause (s) | Trip code |
|---|---|---|
| Over-current | The inverter output was short-circuited, or the motor shaft is locked or has a heavy load. These conditions cause excessive current for the inverter, so the inverter output is turned OFF. The protection circuit operates at approximately 220%(Parameter setting changeable) of the rated output current (ND rated). |
E001 |
| Overload protection*1 | When a motor overload is detected by the electronic thermal function, the inverter trips and turns off its output. | E005 |
| Braking resistor overload protection | When the regenerative braking resistor exceeds the usage time allowance or an over-voltage caused by the stop of the BRD function is detected, the inverter trips and turns off its output. | E006 |
| Over-voltage protection | When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor, the inverter trips and turns off its output. | E007 |
| Memory error*2 | When the built-in memory element has problems due to noise or excessive temperature, the inverter trips and turns off its output. | E008 |
| Under-voltage error*3 | A decrease of internal DC bus voltage below a threshold results in a control circuit fault. This condition can also generate excessive motor heat or cause low torque. The inverter trips and turns off its output. |
E009 |
| Current transformer error | If a strong source of electrical interference is close to the inverter or abnormal operations occur in the built-in CT, the inverter trips and turns off its output. | E010 |
| CPU error*4 | When a malfunction in the built-in CPU has occurred, the inverter trips and turns off its output. | E011 |
| External trip | When a signal to an intelligent input terminal configured as EXT has occurred, the inverter trips and turns off its output. | E012 |
| USP error | An error occurs when power is cycled while the inverter is in RUN mode if the Unattended Start Protection (USP) is enabled. The inverter trips and does not go into RUN mode until the error is cleared. |
E013 |
| Ground fault*5 | The inverter is protected by the detection of ground faults between the inverter output and the motor during power-up tests. This feature protects the inverter only. |
E014 |
| Input over-voltage protection | When the input voltage is higher than the specified value, it is detected 100 seconds after power-up and the inverter trips and turns of its output. The overvoltage detection voltage is about 390 VDC (200 V class) and 780 VDC (400 V class) between PN. (Parameter changeable). | E015 |
| Instantaneous power failure | When power is cut for more than 15ms, the inverter trips and turns off its output. If power failure continues, the error will be cleared. The inverter restarts if it is in RUN mode when power is cycled. |
E016 |
| Temperature detector error | The inverter will display the error code shown on the right if the lowering of cooling-fan speed is detected at the occurrence of the temperature error described below. | E019 |
| Temperature error due to low cooling-fan speed | The inverter will display the error code shown on the right if the lowering of cooling-fan speed is detected at the occurrence of the temperature error described below. | E020 |
| Inverter thermal trip | When the inverter internal temperature is higher than the specified value, the thermal sensor in the inverter module detects the higher temperature of the power devices and trips, turning off the inverter output. | E021 |
| Phase loss input protection*6 | One of three lines of 3-phase power supply is missing. Decision time is about 1s. (When the input phase loss effective function is enabled. |
E024 |
| IGBT error*7 | When an instantaneous over-current has occurred, the inverter trips and turns off its output to protect main circuit element. | E030 |
| Phase loss output protection*8 | One of three lines of 3-phase power output is missing. Decision time is about 1s. (When the output phase loss effective function is enabled. |
E034 |
| Thermistor error | When the thermistor inside the motor detects temperature higher than the specified value, the inverter trips and turns off its output. | E035 |
| Braking error | The inverter turns off its output when it can not detect whether the braking is ON or OFF within waiting time after it has released the brake. (When braking function is enabled.) | E036 |
| Low-speed overload protection | If overload occurs during the motor operation at a very low speed at 0.2 Hz or less, the electronic thermal protection circuit in the inverter will detect the overload and shut off the inverter output. (Note that a high frequency may be recorded as the error history data.) |
E038 |
| Inverter's Overload protection*1 | When the inverter itself overload is detected by the electronic thermal function, the inverter trips and turns off its output. | E039 |
| Modbus (RS-485) communication error | If timeout occurs because of line disconnection during the communication in Modbus-RTU mode, the inverter will display the error code shown on the right. | E041 |
| EzSQ invalid instruction | This trip occurs when an invalid instruction is detected in EzSQ program. | E043 |
| EzSQ Nesting count Error | This trip occurs when number of nesting times is exceeded in EzSQ program. | E044 |
| EzSQ instruction Error | This trip occurs when an can not executed instruction is detected in EzSQ program. | E045 |
| EzSQ User Setting Error 0 to 9 | These trips occur when a user specified trip instruction is executed in the program. | E050 to E059 |
| There is an error in the STO path | For more information, please refer to the P1 functional safety guide. | E090 to E093 |
