16. INDEXER POSITIONING OPERATION
Display Name
Definition
Cause
Action
AE3 Absolute
position
counter warning
Absolute position
encoder pulses faulty.
1. Noise entered the encoder.
Take measures against noise.
2. Encoder faulty.
Change the servo motor.
The multi-revolution
counter value of the
absolute position
encoder exceeded the
maximum revolution
range.
3. The movement amount from the home
position exceeded a 32767 rotation or
37268 rotation in succession.
Make home position setting
again.
The update cycle for
writing the multi-
revolution counter value
of the absolute position
encoder to EEP-ROM is
short.
Refer to POINT in section 16.7.
Refer to POINT in section 16.7.
AE6 Servo
forced
stop
warning
EMG is off.
External forced stop was enabled. (EMG
was turned off.)
Ensure safety and deactivate
forced stop.
AE8 Cooling fan
speed reduction
warning
The speed of the servo
amplifier cooling fan
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.
3. The cooling fan is clogged with foreign
matter and the speed was decreased.
Remove the foreign matter.
AE9 Main circuit off
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 with the one of
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. Change the servo
amplifier/servo motor with the
one of larger capacity.
