Warning No. EB Name: The other axis fault warning
Stop method: All axes stop (warning detected
at both axes).
Warning description In the other axis, alarm demanding all axes stop (11. , 15. , 17. , 24. and 32. ) is output.
Display Name Cause Checkpoint Finding Action
EB.1 The other axis
fault warning (1) Alarm No. 11. is output
in the other axis.
Check that Alarm No.
11. is output in the
other axis. Alarm is output. Remove the cause of
Alarm No. 11. in
other the axis.
(2) Alarm No. 15. is output
in the other axis.
Check that Alarm No.
15. is output in the
other axis. Alarm is output. Remove the cause of
Alarm No. 15. in
other the axis.
(3) Alarm No. 17. is output
in the other axis.
Check that Alarm No.
17. is output in the
other axis. Alarm is output. Remove the cause of
Alarm No. 17. in
other the axis.
(4) Alarm No. 24. is output
in the other axis.
Check that Alarm No.
24. is output in the
other axis. Alarm is output. Remove the cause of
Alarm No. 24. in
other the axis.
(5) Alarm No. 32. is output
in the other axis.
Check that Alarm No.
32. is output in the
other axis. Alarm is output. Remove the cause of
Alarm No. 32. in
other the axis.
Warning No. EC Name: Overload warning 2
Stop method: Axes can operate (detected at
the corresponding axis).
Warning description
The operation, in which current exceeding the rating flows intensively in any of U, V and W phases of the
servo motor, is repeated.
Display Name Cause Checkpoint Finding Action
EC.1 Overload warning
2
(1) During a stop, current
flows intensively in any of
U, V and W phases of the
servo motor repeatedly.
Change the stop position
and check the
reproducibility of the error. Not reproduced. Reduce the
positioning frequency
at the specific
positioning address.
Reproduced. Check (2).
(2) Load is too large or the
capacity is not enough.
Check the effective load
ratio with MR
Configurator. Effective load ratio is
large. Reduce the load.
Use servo amplifier
and servo motor with
larger capacities.
Warning No. ED Name: Output watt excess warning
Stop method: Axes can operate (detected at
the corresponding axis).
Warning description
The status, in which the output wattage (speed x torque) of the servo motor exceed the rated output,
continues steadily.
Display Name Cause Checkpoint Finding Action
ED.1 Output watt
excess
(1) Output wattage of the
servo motor exceeds
150 of the rated output.
Measure motor speed
and torque with MR
Configurator. Output wattage
exceeds 150 of the
rated output. Reduce the servo
motor speed.
Reduce the load.
