When Error Checked Error Processing Corrective Action
•
The servo motor connected is not
as set.
•
Reconsider the system settings.
•
The U, V, and W phases of the
ADU output resulted in a short
circuit or ground fault.
•
Check the servo motor cable.
•
Wiring mistake of the U, V, and W
phases of the ADU output.
•
Correct the servo motor wiring.
•
Damage to the ADU's transistor
module.
•
ADU fault.
•
Change the ADU.
•
Coupling fault of servo motor and
encoder.
•
Change the servo motor.
A
•
The servo motor oscillated.
•
At power-on of servo
amplifier
•
At servo error reset
•
Reconsider the servo parameters.
•
U, V, W in the servo amplifier
outputs have short circuited with
each other.
•
Check if there is a short circuit between
U, V, W of the servo amplifier outputs.
•
U, V, W in the servo amplifier
outputs have shorted to ground.
•
Check if U, V, W of the servo amplifier
outputs have been grounded to the
ground terminal. Check if U, V, W of
the servomotor are grounded to the
core.
If grounding is found, replace the servo
amplifier and/or motor.
•
Incorrect wiring of U, V, W phases
in the servo amplifier outputs.
•
Correct the wiring.
•
The servo amplifier transistor is
damaged.
•
Replace the servo amplifier.
•
Failure of coupling between
servomotor and encoder
•
Replace the servomotor.
•
Encoder cable failure
•
Replace the encoder cable.
•
A servomotor that does not match
the setting has been connected.
•
Check the connected motor set in the
system settings.
•
The servomotor oscillated.
•
Check and adjust the gain value set in
the servo parameters.

M
Overcurrent
•
Noise entered the overcurrent
detection circuit.
•
Check if any relays or valves are
operating in the vicinity.
•
The converter bus voltage has
reached 400 V or more. (800VAC
or more for 400VAC series servo)
•
The frequency of acceleration and
deceleration was too high for the
regenerative ability.
•
The regenerative resistor has been
connected incorrectly.
•
Increase the acceleration time and
deceleration time in the fixed
parameters.
•
Check the connection between C and P
of the terminal block for the terminal
block for regenerative resistance.
•
The regenerative resistor in the
servo amplifier is destroyed.
•
Measure between C and P of the
terminal block for regenerative
resistance with a multimeter; if
abnormal, replace the servo amplifier.
(Measure about 3 minutes after the
charge lamp has gone out.)
•
The power transistor for
regeneration is damaged.
•
Replace the servo amplifier.

M
Overvoltage
•
The power supply voltage is too
high.
•
Measure the input voltage (R, S, T) with
a voltmeter.

error
•
Error in data received from the
servo system CPU
At any time during operation
Immediate stop
•
Check the connection of the motion bus
cable.
•
Check if there is a disconnection in the
motion us cable.
•
Check if the motion bus cable is
clamped correctly.
