8. TROUBLESHOOTING
8 - 10
Alarm No.: 17 Name: Board error
Alarm content A part in the servo amplifier is malfunctioning.
Display Detail name Cause Check method Check result Action
17.1 Board error 1 (1) A current detection
circuit is malfunctioning.
It occurs. Replace the servo
amplifier. Check if the alarm
occurs during the servo-
on status.
It does not occur. Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
etc. It has a failure. Take countermeasures
against its cause.
17.3 Board error 2 Check it with the check method for [AL. 17.1].
17.4 Board error 3 (1) It is repeatable. Replace the servo
amplifier. The servo amplifier
recognition signal was
not read properly. Disconnect the cables
except the power supply,
and then check the
repeatability.
It is not repeatable. Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
etc. It has a failure. Take countermeasures
against its cause.
Alarm No.: 19 Name: Memory error 3 (FLASH-ROM)
Alarm content A part (Flash-ROM) in the servo amplifier is failure.
Display Detail name Cause Check method Check result Action
19.1 FLASH-ROM
error 1
(1) The Flash-ROM is
malfunctioning.
It is repeatable. Replace the servo
amplifier. Disconnect the cables
except the power supply,
and then check the
repeatability.
It is not repeatable. Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
etc. It has a failure. Take countermeasures
against its cause.
19.2 FLASH-ROM
error 2
Check it with the check method for [AL. 19.1].
Alarm No.: 1A Name: Servo motor combination error
Alarm content The combination of servo amplifier and servo motor is incorrect.
Display Detail name Cause Check method Check result Action
1A.1 (1) The combination is
incorrect. Use them in the correct
combination. Servo motor
combination
error The servo amplifier and
the servo motor was
connected incorrectly. Check the model name
of the servo motor and
corresponding servo
amplifier.
The combination is
correct. Check (2).
(2) An encoder is
malfunctioning.
Replace the servo motor,
and then check the
repeatability. It is not repeatable. Replace the servo motor.
Alarm No.: 1E Name: Encoder initial communication error 2
Alarm content An encoder is malfunctioning.
Display Detail name Cause Check method Check result Action
1E.1 (1) It is not repeatable. Replace the servo motor. Encoder
malfunction An encoder is
malfunctioning. Replace the servo motor,
and then check the
repeatability.
It is repeatable. Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
vibration, etc. It has a failure. Take countermeasures
against its cause.
