Error Codes - Hitachi X200 Series Quick Reference Manual

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.

Name
Inverter output was short-circuited
Motor shaft is locked
Load is too heavy
A dual voltage motor is wired
incorrectly
Note: The X200 will over-current trip at
nominally 200% of the rated current.
DC braking power (A_54) set too high
Current transformer / noise error
Motor overload is detected by the
electronic thermal function
DC bus voltage exceeds a threshold,
due to regeneration energy from the
motor
Built-in EEPROM memory
experienced noise, high temperature,
etc.
DC bus voltage decreased enough to
cause a control circuit fault
Instantaneous power failure occurred
Built-in CPU had internal error
[EXT] input signal detected
When (USP) was enabled, an error
occurred when power was applied while
a Run signal was present
A ground fault was detected between
the inverter output and the motor. This
feature protects the inverter, and does
not protect humans.
Input voltage was higher than the
specified value, 100 sec. after powerup
Inverter internal temperature is
above the threshold
Refer to E_01~E_04
Thermistor input, [5] and [L] is over
the temperature threshold
Emergency stop signal has given
Communication error on RS485
MODBUS communication
Low input voltage caused the inverter
to turn OFF the motor output and try to
restart. If unsuccessful, a trip occurs.
