Error Codes
An error code will appear on the display automatically when a fault causes the inverter to trip The
following table lists the cause associated with the error.
Error
Code
Name Cause(s)
E01
Over current event while at constant
speed
E02
Over current event
during
deceleration
E03
Over current event
during
acceleration
E04
Over current event during
other conditions
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 dual-voltage motor is wired incorrectly.
E05
Overload protection
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
EEPROM error
When the built-in EEPROM 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.
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
When the Unattended Start Protection (LJSP) 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
The inverter is protected by the detection of ground faults between the
inverter output and the motor during powerup 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 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 [CM1] and the
inverter has sensed the temperature is too high, the inverter trips and
turns OFF the output.
---U
Under-voltage (brownout) 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.
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.
Trip History and Inverter Status
Always find the cause of the fault before clearing it. When a fault occurs, the inverter stores
important performance data at the moment of the fault. To access the data, use the monitor
functions (D_xx) and select D_08 for details about the present fault (E
n
), or the error code for the
past two trip events (E
n-1
) and E
n-2
) using the D_09 Trip History function.
The following Monitor Menu map shows how to access the error codes. When fault(s) exist, you
can review their details by first selecting the proper function: D_08 displays current trip data, and
D09 displays trip history.
