Monitoring Trip Events, History, & Conditions Section 6-2
procedure 6-3 Restoring Factory Default Settings on page 245 (setting
B084=00 will clear the trip history but leave inverter settings intact).
6-2-2 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.
Erro
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.
The dual-voltage motor is wired incorrectly.
E02 Over-current event during
deceleration
E03 Over-current event during
acceleration
E04 Over-current event during
other conditions
E05 Overload protection When a motor overload is detected by the
electronic thermal function, the inverter trips
and turns OFF its output.
Check if the application can accept softer accel-
eration rates to minimize peak currents F002/
F202/A092/A292).
Check if motor parameters are not correctly set
(H020 to H034), depending in motor control
method (A044/A244).
E06 Braking resistor overload
protection
When the BRD operation rate exceeds the set-
ting of "b090", this protective function shuts off
the inverter output and displays the error code.
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 prob-
lems 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 detec-
tion system, the inverter will shut off its output
and display the error code.
E11 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 (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 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 pro-
tect humans.
E15 Input over-voltage The inverter tests for input over-voltage after
the inverter has been in Stop Mode for 100 sec-
onds. If an over-voltage condition exists, the
inverter enters a fault state. After the fault is
cleared, the inverter can enter Run Mode again.
