Meaning
The motor has overheated.
The motor has overheated.
The deceleration time is too short and
the regenerative energy from the
motor is too large.
The load is too heavy. The accelera-
tion time, deceleration time, and cycle
time are too short.
The V/f characteristics voltage is too
high or too low.
The Motor Rated Current (E2-01) is
incorrect.
The load is too heavy. The accelera-
tion time, deceleration time and cycle
time are too short.
The V/f characteristics voltage is too
high or too low.
The Inverter capacity is too low.

Corrective Actions
Check the size of the load and the
length of the acceleration, deceler-
ation, and cycle times.
Check the V/f characteristics.
Check the motor temperature
input on terminals A1 and A2.
Check the size of the load and the
length of the acceleration, deceler-
ation, and cycle times.
Check the V/f characteristics.
Check the motor temperature
input on terminals A1 and A2.
• Reduce the load, increase the
deceleration time, or reduce the
motor speed.
• Change to a Braking Resistor
Unit.
• Try turning the power supply
off and on.
• Replace the Inverter if the fault
continues to occur.
Check the size of the load and the
length of the acceleration, deceler-
ation, and cycle times.
Check the V/f characteristics.
Check the Motor Rated Current
(E2-01).
Check the size of the load and the
length of the acceleration, deceler-
ation, and cycle times.
Check the V/f characteristics.
Replace the Inverter with one that
has a larger capacity.
• Make sure that the settings in
L6-02 and L6-03 are appropri-
ate.
• Check the mechanical system
and correct the cause of the
overtorque.
• Make sure that the current set-
ting in L6-05 and time setting in
L6-06 are appropriate.
• Check the mechanical system
and correct the cause of the
overtorque.
