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 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
The inverter tests for input over-voltage after the
inverter has been in Stop Mode for 100 seconds. If an
over-voltage condition exists, the inverter enters a
fault state. After the fault is cleared, the inverter can
enter Run Mode again.
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 3 0
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.
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.
