3.5 Alarm occurrence timing chart
CAUTION
When an alarm has occurred, remove its cause, make sure that the operation
signal is not being input, ensure safety, and reset the alarm before restarting
operation.
As soon as an alarm occurs, turn off Servo-on (SON) and power off the main
circuit.
When an alarm occurs in the servo amplifier, the base circuit is shut off and the servo motor is coated to a
stop. Switch off the main circuit power supply in the external sequence. To reset the alarm, switch the
control circuit power supply from off to on, press the "SET" button on the current alarm screen, or turn
the reset (RES) from off to on. However, the alarm cannot be reset unless its cause is removed.

about
(1) Overcurrent, overload 1 or overload 2
If operation is repeated by switching control circuit power off, then on to reset the overcurrent
(AL.32), overload 1 (AL.50) or overload 2 (AL.51) alarm after its occurrence, without removing
its cause, the servo amplifier and servo motor may become faulty due to temperature rise.
Securely remove the cause of the alarm and also allow about 30 minutes for cooling before
resuming operation.
(2) Regenerative alarm
If operation is repeated by switching control circuit power off, then on to reset the regenerative
(AL.30) alarm after its occurrence, the external regenerative brake resistor will generate heat,
resulting in an accident.
(3) Instantaneous power failure
Undervoltage (AL.10) occurs when the input power is in either of the following statuses.
A power failure of the control circuit power supply continues for 60ms or longer and the
control circuit is not completely off.
The bus voltage dropped to 200VDC or less for the MR-J2S- A, or to 158VDC or less for the
MR-J2S-
A1.
(4) In position control mode (incremental)
When an alarm occurs, the home position is lost. When resuming operation after deactivating
the alarm, make a home position return.
