51.1 Thermal
overload error
3 during
operation
(1) The servo motor power
cable was
disconnected.
Check the servo
motor power cable.
It is disconnected.
Repair or replace
the servo motor
power cable.
[A]
[B]
[WB]
[RJ010]
[GF]
It is not
disconnected.
Check (2).
(2) The connection of the
servo motor is incorrect.
Check the wiring of
U/V/W.
It is incorrect.
Connect it correctly.
It is correct.
Check (3).
(3) The connection of the
encoder cable is
incorrect.
Check if the encoder
cable is connected
correctly.
It is incorrect.
Connect it correctly.
It is correct.
Check (4).
(4) The torque is
insufficient.
Check the peak load
ratio.
The torque is
saturated.
Reduce the load or
review the operation
pattern. Or use a
larger capacity
motor.
The torque is not
saturated.
Check (5).
(5) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the
repeatability.
It is not repeatable.
Replace the servo
amplifier.
It is repeatable.
Check (6).
(6) An encoder or servo
motor is malfunctioning.
Replace the servo
motor, and then check
the repeatability.
It is not repeatable.
Replace the servo
motor.
51.2 Thermal
overload error 3
during a stop
(1) A moving part collided
against the machine.
Check if it collided.
It collided.
Check operation
pattern.
It did not collide.
Refer to (2).
(2) The servo motor power
cable was
disconnected.
Check it with the check method for [AL. 51.1].
(3) The connection of the
servo motor is
incorrect.
(4) The connection of the
encoder cable is
incorrect.
(5) The torque is
saturated.
(6) The servo amplifier is
malfunctioning.
(7) An encoder is
malfunctioning.
