Name: Overload 1
Stop method: Corresponding axis stops
Alarm description
Load exceeds overload protection characteristic of servo amplifier.
Display Name
Cause
Checkpoint
Finding
Action
50.3
(1) Machine struck something. Examine checkpoints described in the alarm display "50.2".
(2) Power cable is cut.
Thermal overload
error 4 during
operation
(3) Incorrect
connections
to/from the linear servo
motor.
(4) Resolution of the linear
encoder and the
resolution setting of the
parameter are different.
(5) Polarity of the linear
encoder is incorrect.
(Installation direction is
incorrect.)
(6) Initial magnetic pole
detection is not
performed.
(7) Linear encoder is faulty.
(8) Servo amplifier is used in
excess of its continuous
output current.
(9) Servo system is instable
and causing oscillation.
(10) Servo amplifier is faulty.
50.4 Thermal
overload
error 1 during a
stop
(1) Servo amplifier is used in
excess of its continuous
output current.
Check the effective load
ratio with MR
Configurator.
Effective load ratio is
large.
Reduce load.
Check operation
pattern.
Use servo motor that
provides larger output.
Effective load ratio is
small.
Check (2).
(2)
Check for hunting.
Hunting occurs.
Adjust the gain.
Hunting occurs during
servo lock.
Hunting does not
occur.
Check (3).
(3)
Not reset.
Reset the alarm after
sufficient cool-off time.
After the overload alarm
has been output, the
operation is restarted
without having cool-off
time.
Check if the alarm is
reset after waiting 15
minutes or longer
subsequent to the output
of the alarm.
Reset. Check
(4).
(4) Servo amplifier is faulty.
Replace the servo
amplifier, and check the
reproducibility of the error.
Not reproduced.
Replace the servo
amplifier.
