Servo Alarm
Cause and Remedy
The initial magnetic pole detector did not work normally.
(Cause 1) A collision was caused.
(Remedy) Review the composition of the machine.
(Cause 2) The accuracy is low in detecting the initial magnetic
pole.
(Remedy) Review the setting of Parameter No. 97 (Magnetic
Pole Detection Voltage Level LPWM).
(Cause 3) Defective Wiring for U, V, and W
(Remedy) Review the wire distribution of U, V, and W.
(Cause 4) The resolution of the linear scale signal is different
from the specified one.
(Remedy) Check how the linear scale is mounted.
27 Initial Magnetic
Pole Detection
Error
(Cause 5) The limit switch is not working.
(Remedy) Connect the limit switch correctly.
Set Parameter No. 57 to turn on the limit switch
forcibly.
The margin of the linear scale has deteriorated.
(Cause 1) The temperature of the linear scale is too high.
(Remedy) Check the temperature of the linear scale and
inquire the details of the linear scale to the maker.
28 Linear Scale
Error 2
(Cause 2) The signal level of the linear scale went down.
(Remedy) Check how the linear scale is mounted.

Servo Alarm
Cause and Remedy
The linear scale emitted an alarm.
(Cause 1) The speed of the linear scale exceeded the allowable
range.
(Remedy) Change the speed of the linear scale in the
allowable range.
(Cause 2) Some noises are mixed.
(Remedy) Take some countermeasures against noises.
(Cause 3) Alarm from Linear Scale
(Remedy) Inquire the details of the remedial procedures to
the maker of the linear scale.
2A Scale Error 1
(Cause 4) The scale and the detection head are not mounted
correctly in place.
(Remedy) Position the scale and the detection head
correctly.
Permissible regenerative power of the built-in regenerative
brake resistor or regenerative brake option is exceeded.
(Cause 1) Mismatch between used regenerative brake option
and parameter No. 2 setting
(Remedy) Set correctly.
30 Regenerative
error
(Cause 2) Built-in regenerative brake resistor or regenerative
brake option is not connected.
(Remedy) Connect correctly.

Servo Alarm
Cause and Remedy
(Cause 3) High-duty operation or continuous regenerative
operation caused the permissible regenerative power
of the regenerative brake option to be exceeded.
[Checking Method]: Call the status display and check the
regenerative load ratio.
(Remedy 1) Reduce the frequency of positioning.
(Remedy 2) Use the regenerative brake option of larger
capacity.
(Remedy 3) Reduce the load.
(Cause 4) Power supply voltage is abnormal.
MR-J2S-B: 260 V or more
MR-J2S-B1: 135 V or more
(Remedy) Review power supply.
(Cause 5) Built-in regenerative brake resistor or regenerative
brake option faulty.
(Remedy) Change servo amplifier or regenerative brake
option.
Regenerative transistor fault
(Cause 6) Regenerative transistor faulty.
[Checking Method]: 1) The regenerative brake option has
overheated abnormally.
2) The alarm occurs even after
removal of the built-in
regenerative brake resistor or
regenerative brake option.
(Remedy) Change the servo amplifier.
