Servo Alarm
Cause and Remedy
Power supply voltage dropped.
MR-J2S-B:160 V AC or less
(Cause 1) Power supply voltage is low.
(Cause 2) There was an instantaneous control circuit power
failure of 60 ms or longer.
(Cause 3) Shortage of power supply capacity caused the
power supply voltage to drop at start, etc.
(Cause 4) Power was restored after the bus voltage had
dropped to 200 V DC. (Main circuit power switched
on within 5 s after it had switched off.)
(Remedy) Review the power supply.
(Cause 5) Faulty parts in the servo amplifier
[Checking Method]: Alarm (A.10) occurs if power is
switched on after all connectors are
disconnected.
(Remedy) Change the servo amplifier.
Power supply voltage dropped.
MR-MD08: 40 V AC or less
MR-MD18 and MR-MD18-FJ: 35 V AC or less
(Cause 1) Power supply voltage is low.
(Cause 2) There was an instantaneous control circuit power
failure of 15 ms or longer.
(Cause 3) Shortage of power supply capacity caused the
power supply voltage to drop at start, etc.
(Cause 4) Main circuit power switched on within 5 s after it
had switched off.
(Remedy) Review the power supply.
10 Undervoltage
(Cause 5) Faulty parts in the servo amplifier
[Checking Method]: Alarm (A.10) occurs if power is
switched on after all connectors are
disconnected.
(Remedy) Change the servo amplifier.

Servo Alarm
Cause and Remedy
RAM or ROM memory fault 12 Memory error 1
(Cause 1) Faulty parts in the servo amplifier
[Checking Method]: Alarm (any of 12, 13 or 15) occurs if
power is switched on after
disconnection of all cables but the
control circuit power supply cables.
(Remedy) Change the servo amplifier.
Printed board fault 13 Clock error
(Cause 1) Faulty parts in the servo amplifier
[Checking Method]: Alarm (any of 12, 13 or 15) occurs if
power is switched on after
disconnection of all cables but the
control circuit power supply cables.
(Remedy) Change the servo amplifier.
EEP-ROM fault 15 Memory error 2
(Cause 1) Faulty parts in the servo amplifier
[Checking Method]: Alarm (any of 12, 13 or 15) occurs if
power is switched on after
disconnection of all cables but the
control circuit power supply cables.
(Remedy) Change the servo amplifier.
Communication error occurred between encoder and servo
amplifier.
(Cause 1) Encoder connector (CN2) disconnected.
(Remedy) Connect correctly.
(Cause 2) Encoder fault
(Remedy) Change the servo motor.
16 Encoder error 1
(Cause 3) Encoder cable faulty (Wire breakage or shorted)
(Remedy) Repair or change cable.

Cause and Remedy
CPU/parts fault 17 Board error
(Cause 1) Faulty parts in the servo amplifier
[Checking Method]: Alarm (any of 17 or 19) occurs if
power is switched on after
disconnection of all cables but the
control circuit power supply cables.
(Remedy) Change the servo amplifier.
ROM memory fault 19 Memory error 3
(Cause 1) Faulty parts in the servo amplifier
[Checking Method]: Alarm (any of 17 or 19) occurs if
power is switched on after
disconnection of all cables but the
control circuit power supply cables.
(Remedy) Change the servo amplifier.
Wrong combination of servo amplifier and servo motor. 1A Motor
combination
error
(Cause 1) Wrong combination of servo amplifier and servo
motor connected.
(Remedy) Use correct combination.
Communication error occurred between encoder and servo
amplifier.
(Cause 1) Encoder connector (CN2) disconnected.
(Remedy) Connect correctly.
(Cause 2) Encoder fault
(Remedy) Change the servo motor.
20 Encoder error 2
(Cause 3) Encoder cable faulty (Wire breakage or shorted)
(Remedy) Repair or change cable.
