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.
E 1 1
E 2 2
CPU error A malfunction in the built-in CPU has occurred, so
the inverter trips and turns OFF its output to the
motor.
E 1 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.
E 1 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.
E 1 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.
E 1 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.
E 2 1
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.
E 2 3
Gate array error An internal inverter error has occurred in communica-
tions between the CPU and gate array IC.
E 3 5
Thermistor When a thermistor is connected to terminals [6] and
[L] and the inverter has sensed the temperature is too
high, the inverter trips and turns OFF the output.
E 6 0
Communications error The inverter’s watchdog timer for the communica-
tions network has timed out.
- - -
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.

OVSRC(E15) trip level is relatively changed for 200/400V class in 3440(Core) and
3524(I/O) software.
