10. TROUBLESHOOTING
10.2.2 Remedies for alarms
CAUTION
When any alarm has occurred, eliminate its cause, ensure safety, then reset the
alarm, and restart operation. Otherwise, injury may occur.
If an absolute position erase (AL.25) occurred, always make home position setting
again. Otherwise, misoperation may occur.
As soon as an alarm occurs, turn off Servo-on (SON) and power off the main
circuit.
POINT
When any of the following alarms has occurred, always remove its cause
and allow about 30 minutes for cooling before resuming operation. If
operation is resumed by switching control circuit power off, then on to reset
the alarm, the servo amplifier and servo motor may become faulty.
Regenerative error (AL.30)
Overload 1 (AL.50)
Overload 2 (AL.51)
The alarm can be deactivated by switching power off, then on press the
"SET" button on the current alarm screen or by turning on the reset (RES).
For details, refer to Section 10.2.1.
When an alarm occurs, the trouble (ALM) switches off and the dynamic brake is operated to stop the
servomotor. At this time, the display indicates the alarm No.
The servo motor comes to a stop. Remove the cause of the alarm in accordance with this section. The
optional MR Configurator (servo configuration software) may be used to refer to the cause.
Display Name Definition Cause Action
1. Power supply voltage is low.
2. There was an instantaneous
control power failure of 60ms or
longer.
3. Shortage of power supply capacity
caused the power supply voltage to
drop at start, etc.
4. The bus voltage dropped to
200VDC.
Review the power supply.
AL.10 Undervoltage Power supply
voltage dropped.
MR-J2S-
A:
160VAC or less
MR-J2S-
A1:
83VAC or less
5. Faulty parts in the servo amplifier
Checking method
Alarm (AL.10) occurs if power is
switched on after disconnection
of all cables but the control
circuit power supply cables.
Change the servo amplifier.
AL.12 Memory error 1 RAM, memory fault
AL.13 Clock error Printed board fault
Faulty parts in the servo amplifier
Checking method
Alarm (any of AL.11 and AL.13)
occurs if power is switched on
after disconnection of all cables
but the control circuit power
supply cables.
Change the servo amplifier.
