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.

Servo Alarm
Cause and Remedy
Ground fault occurred at the servo motor outputs (U, V, and
W phases) of the servo amplifier.
(Cause 1) Power input wires and servo motor output wires are
in contact at main circuit terminal block (TE1).
(Remedy) Connect correctly.
(Cause 2) Sheathes of servo motor power cables deteriorated,
resulting in ground fault.
(Remedy) Change the cable.
24 Main circuit error
(Cause 3) Main circuit of servo amplifier failed.
[Checking Method]: Alarm (24) occurs if the servo is
switched on after disconnecting the
U, V and W power cables from the
servo amplifier.
(Remedy) Change the servo amplifier.
Absolute position data in error
(Cause 1) Battery voltage low
(Cause 2) Battery cable or battery is faulty.
(Remedy) Change battery. Always make home position
setting again.
Power was switched on for the first time in the absolute
position detection system.
25 Absolute
position erase
(Cause 3) Super capacitor of the absolute position encoder is
not charged.
(Remedy) After leaving the alarm occurring for a few
minutes, switch power off, then on again.
Always make home position setting again.
