Inverter
hardware
fault
OUOC
1: Overvoltage exists.
2: Overcurrent exists.
1: Remove the overvoltage.
2: Remove the overcurrent.
Short circuit
to ground
fault
GND
The motor is short circuited to
the ground.
Replace the cable or motor.
Accumulative
running time
reached
END1
The accumulative running
time reaches the setting
value.
Clear the record through the
parameter initialization
function.
Accumulative
power-on
time reached
END2
The accumulative power- on
time reaches the setting
value.
Clear the record through the
parameter initialization
function.
Zero load
LOAD
The inverter operation
current is lower than P9.64.
Check that the load is
disconnected or the setting of
P9.64 and P9.65 is correct.
PID feedback
lost during
running
PIDE
The PID feedback is lower
than the setting of PA.26.
Check the PID feedback signal
or set PA.26 to a proper value.
Pulse-by-pulse
current limit
fault
CBC
1: The load is too high or the
rotor is blocked on the motor.
2: The inverter model has a
too low power class.
1: Reduce the load and check
the motor and mechanical
condition.
2: Select an inverter of higher
power class
Too large
speed
deviation fault
ESP
1: The encoder parameters
are set incorrectly.
2: The motor auto-tuning is
not performed.
3: Parameters of too large
speed deviation P9.69 and
P9.70 are set incorrectly.
1: Set the encoder parameters
properly.
2: Perform the motor auto-
tuning.
3: Set P9.69 and P9.70
correctly based on the actual
situation.
