Over-current
protection
14 0 Current through the converter portion has
exceeded the specified value.
1) Failure of servo driver (failure of the
circuit, IGBT or other components)
2) Short of the motor wire (U, V and W)
3) Earth fault of the motor wire
4) Burnout of the motor
5) Poor contact of the motor wire.
6) Timing of pulse input is same as or
earlier than Servo-ON.
1) Turn to Servo-ON, while disconnecting the
motor. If error occurs immediately, replace
with a new driver.
2) Check that the motor wire (U, V and W) is
not shorted, and check the branched out
wire out of the connector. Make a correct
wiring connection.
3) Measure the insulation resistance between
motor wires, U, V and W and earth wire. In
case of poor insulation, replace the motor.
4) Check the balance of resister between
each motor line, and if unbalance is found,
replace the motor.
5) Check the loose connectors. If they are, or
pulled out, fix them securely.
6) Enter the pulses 100ms or longer after
Servo-ON.

Over-heat
protection
15 0 Temperature of the heat sink or power
device has been risen over the specified
temperature.
1) Ambient temperature has risen over
the specified temperature.
2) Over-load
1) Improve the ambient temperature and
cooling condition.
2) Increase the capacity of the driver
and motor. Set up longer acceleration/
deceleration time. Lower the load.
Over-load
protection
16 0 Torque command value has exceeded
the over-load level set with Pr5.12
(Setup of over-load level) and resulted in
overload protection according to the time
characteristics (described later)
1) Load was heavy and actual torque has
exceeded the rated torque and kept
running for a long time.
2) Oscillation and hunching action due to
poor adjustment.
Motor vibration, abnormal noise.
Inertia ratio (Pr0.04) setup error.
3) Miswiring, disconnection of the motor.
4) Machine has collided or the load has
gotten heavy. Machine has been
distorted.
5) Electromagnetic brake has been kept
engaged.
6) While wiring multiple axes, miswiring
has occurred by connecting the motor
cable to other axis.
• The over-load protection time characteristics are described on P.6-13.
Caution
Once this error occurs, it cannot be cleared at least for 10 sec.
Check that the torque (current) does not
oscillates nor fluctuate up an down very much
on the graphic screen of the PANATERM.
Check the over-load alarm display and load
factor with the PANATERM.
1) Increase the capacity of the driver
and motor. Set up longer acceleration/
deceleration time. Lower the load.
2) Make a re-adjustment.
3) Make a wiring as per the wiring diagram.
Replace the cables.
4) Remove the cause of distortion. Lower the
load.
5) Measure the voltage between brake
terminals. Release the brake
6) Make a correct wiring by matching the
correct motor and encoder wires.

• When protective function marked with
*
in the protective function table is activated, it can-
not be disabled by the alarm clear input (A-CLR). To return to the normal operation, turn off
power, remove the cause, and then turn on power again.
