50.2 Thermal
overload error
2 during
operation
Check it with the check method for [AL. 50.1].
50.3 Thermal
overload error
4 during
operation
50.4 Thermal
overload error
1 during a stop
(1) A moving part collided
against the machine.
Check if it collided.
It collided.
Check operation
pattern.
[A]
[B]
[WB]
[RJ010]
[GF]
It did not collide.
Check (2).
(2) The servo motor power
cable was
disconnected.
Check the servo motor
power cable.
It is disconnected.
Repair or replace
the servo motor
power cable.
It is not
disconnected.
Check (3).
(3) Hunting occurs during
servo-lock.
Check if the hunting
is occurring.
The hunting is
occurring.
Adjust gains.
The hunting is not
occurring.
Check (4).
(4)
The
electromagnetic
brake has not released.
(The electromagnetic
brake has been
activated.)
Check if the
electromagnetic brake
is released.
It is not released.
Release the
electromagnetic
brake.
It is released.
Check (5).
(5) A current was applied to
the servo amplifier in
excess of its continuous
output current.
Check the effective
load ratio.
The effective load
ratio is high.
Reduce the load. Or
use a larger capacity
motor.
The effective load
ratio is small.
Check (6).
(6)
The
connection
destination of the
encoder cable is
incorrect.
Check the connection
destinations of CN2A,
CN2B, and CN2C.
It is not correct.
Connect it correctly. [WB]
It is correct.
Check (7).
(7) The servo system is
unstable and
resonating.
Check if it is
resonating.
It is resonating.
Adjust gains.
[A]
[B]
[WB]
[RJ010]
[GF]
It is not resonating.
Check (8).
(8) 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 (9).
(9) The encoder, servo
motor, or linear encoder
is malfunctioning.
Replace the servo
motor or linear
encoder, and then
check the
repeatability.
It is not repeatable.
Replace the servo
motor or linear
encoder.
50.5 Thermal
overload error
2 during a stop
Check it with the check method for [AL. 50.4].
50.6 Thermal
overload error
4 during a stop
