AE8 Cooling
fan
speed
reduction warning
The speed of the servo
amplifier decreased to or
below the warning level.
(This warning is not
displayed with MR-J3-
70T/100T among servo
amplifiers equipped with a
cooling fan.)
1. Cooling fan life expiration (Refer to
section 2.5.)
Change the cooling fan of the
servo amplifier.
2. The power supply of the cooling fan is
broken.
Change the servo amplifier.

warning
Servo-on (SON) was
switched on with main
circuit power off.
Switch on main circuit power.
AEC Overload
warning
2
Operation, in which a
current exceeding the
rating flew intensively in
any of the U, V and W
phases of the servo
motor, was repeated.
During a stop, the status in which a current
flew intensively in any of the U, V and W
phases of the servo motor occurred
repeatedly, exceeding the warning level.
1. Reduce the positioning
frequency.
2. Reduce the load.
3. Change the servo amplifier/
servo motor to the one with
larger capacity.
AED
Output watt excess
warning
The status, in which the
output wattage (speed
torque) of the servo motor
exceeded the rated
output, continued steadily.
Continuous operation was performed with
the output wattage (speed torque) of the
servo motor exceeding 150% of the rated
output.
1. Reduce the servo motor
speed.
2. Reduce the load.
3. Replace the servo amplifier/
servo motor with the one of
larger capacity.
