Display
Detail name
Cause
Check method
Check result
Action
The brake is
operating.
Review the wiring.
1) The electromagnetic brake
is operating.
Check if the
electromagnetic brake
does not operate during
operation.
The brake is not
operating.
Check 2).
The effective load
ratio is high.
Reduce the load.
Check operation pattern.
Switch to a larger capacity
servo motor.
2) Servo amplifier was used in
excess of its continuous
output current.
Check the effective load
ratio with MR
Configurator.
The effective load
ratio is small.
Check 3).
It is resonating.
Adjust gains.
Check the applied voltage
of the main circuit is
48VDC when 24VDC is set
for the main circuit power
supply.
3) The servo system is
unstable and resonating.
Check if it is resonating.
It is not resonating.
Check 4).
It was not released.
Take enough time before
resetting the alarm.
4) The motor was driven
without taking a cooling
time after the overload
alarm occurred.
Check if the alarm was
released after 30
minutes from alarm
occurrence.
It was released.
Check 5).
50.1 Thermal
overload error 1
during
operation
5) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the repeatability.
It is not repeatable.
Replace the servo
amplifier.
The brake is
operating.
Review the wiring.
1) The electromagnetic brake

Check 3).
The hunting is
occurring.
Make gain adjustment.
3) Hunting occurs during
servo-lock.
Check if the hunting is
occurring.
The hunting is not
occurring.
Check 4).
It was not released.
Take enough time before
resetting the alarm.
4) The motor was driven
without taking a cooling
time after the overload
alarm occurred.

overload error 1
during a stop
5) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the repeatability.
It is not repeatable.
Replace the servo
amplifier.
