Monitoring Trip Events, History, & Conditions

Troubleshooting

and Maintenance

6–6

NOTE: If an EEPROM error (E08) occurs, be sure to confirm the parameter data values

are still correct. If the power is turned OFF while the [RS] (Reset) intelligent input

terminal is ON, an EEPROM error will occur when power is restored.

E1 0

CT (current transformer)

error

If a strong source of electrical interference is close to

the inverter or a fault occurs in a built-in CT (current

transformer), the inverter trips and turns its output

OFF.

E1 1

E22

CPU error A malfunction in the built-in CPU has occurred, so

the inverter trips and turns OFF its output to the

motor.

E1 2

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.

E1 3

USP 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.

E1 4

Ground fault The inverter is protected by the detection of ground

faults between the inverter output and the motor upon

during powerup tests. This feature protects the

inverter, and does not protect humans.

E1 5

Input over-voltage When the input voltage is higher than the specified

value, it is detected 100 seconds after powerup and

the inverter trips and turns OFF its output.

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.

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.

---

Under-voltage (brown-

out) with output shutoff

Due to low input voltage, the inverter turns its output

OFF and tries to restart. If it fails to restart, then the

alarm trips to record the under-voltage error event.
