Error Codes
The X200 series inverters will trip on over-current, over-voltage, and
under-voltage to protect the inverter. The motor output turns OFF,
allowing the motor to free-run to a stop. Press the Stop/Reset key to
reset the inverter and clear the error.
Basic Error Codes
Error
Code Name Probable Cause(s)
E_01 Over current event
while at constant speed
E_02 Over current event
during deceleration
E_03 Over current event
during acceleration
yInverter output was short-circuited
yMotor shaft is locked
yLoad is too heavy
yA dual voltage motor is wired
incorrectly
Note: The X200 will over-current trip at
nominally 200% of the rated current.
E_04 Over current event for
other conditions
yDC braking power (A_54) set too high
yCurrent transformer / noise error
E_05 Overload protection yMotor overload is detected by the
electronic thermal function
E_07 Over voltage protection
yDC bus voltage exceeds a threshold,
due to regeneration energy from the
motor
E_08 EEPROM error
yBuilt-in EEPROM memory
experienced noise, high temperature,
etc.
E_09 Under voltage error
yDC bus voltage decreased enough to
cause a control circuit fault
yInstantaneous power failure occurred
E_11 CPU error yBuilt-in CPU had internal error
E_12 External trip y[EXT] input signal detected
E_13 USP (Unattended Start
Protection)
yWhen (USP) was enabled, an error
occurred when power was applied while
a Run signal was present
E_14 Ground fault
yA ground fault was detected between
the inverter output and the motor. This
feature protects the inverter, and does
not protect humans.
E_15 Input over-voltage yInput voltage was higher than the
specified value, 100 sec. after powerup
E_21 Inverter thermal trip yInverter internal temperature is
above the threshold
E_30 Driver error Refer to E_01~E_04
E_35 Thermistor yThermistor input, [5] and [L] is over
the temperature threshold
E_37 Emergency stop yEmergency stop signal has given
E_60 Communications error yCommunication error on RS485
MODBUS communication
- - -
Under-voltage
(brownout) with output
shutoff
yLow input voltage caused the inverter
to turn OFF the motor output and try to
restart. If unsuccessful, a trip occurs.
