| Error Code |
Name | Cause(s) |
|---|---|---|
| E01 | Over-current event while at constant speed | 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. |
| E02 | Over-current event during deceleration | |
| E03 | Over-current event during acceleration | |
| E04 | Over-current event during other conditions | |
| E05 | Overload protection *1 | When a motor overload is detected by the electronic thermal function, the inverter trips and turns OFF its output. |
| E07 | Over voltage protection | When the DC bus voltage exceeds a threshold, due to regenerative energy from the motor. |
| E08 | Memory error *2,3,6 | When the built-in memory has problems due to noise or excessive temperature, the inverter trips and turns OFF its output to the motor. |
| E09 | Under-voltage error | 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. |
| E10 | Current detection error | If an error occurs in the internal current detection system, the inverter will shut off its output and display the error code. |
| E11 E22 |
CPU error | A malfunction in the built-in CPU has occurred, so the inverter trips and turns OFF its output to the motor. |
| E12 | External trip | A signal on an intelligent input terminal configured as EXT has occurred. The inverter trips and turns OFF the output to the motor. |
| E13 | USP *4 | When the Unattended Start Protection (USP) is enabled, an error occurred when power is applied while a Run signal is present. The inverter trips and does not go into Run Mode until the error is cleared. |
| E14 | 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, and does not protect humans. |
| E15 | Input over-voltage | When the input voltage is higher than the specified value, it is detected 100 seconds after power up and the inverter trips and turns OFF its output. |
| E19 | Inverter thermal detection system error | When the cooling fin thermal sensor in the inverter detect disconnection etc, inverter trips. |
| E21 | Inverter thermal trip | When the inverter internal temperature is above the threshold, the thermal sensor in the inverter module detects the excessive temperature of the power devices and trips, turning the inverter output OFF. |
| E26 | Control circuit error | When abnormality occurred on a control circuit board, I make a error code |
| 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. |
| E34 | Output phase loss protection | Output Phase Loss Logic Detection (There are undetectable terms of use.) |
| 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 failure | When the connection between inverter and operator keypad failed, inverter trips and displays the error code. |
| E41 | Communications error | The inverter's watchdog timer for the communications network has timed out. |
