Symptom Cause Comment Solution
Speed loop gain value
too high.
—
Reduce speed loop gain
(Pn100) preset value.
Increase integration time
constant (Pn101).
High rotation speed
overshoot on
starting
and stopping.
Speed loop gain is too
low compared to
position loop gain.
—
Increase the value of
parameter Pn100 (speed
loop gain).
Reduce the integration time
constant (Pn101).
Ambient temperature
too high
Measure servomotor
ambient temperature.
Reduce ambient temperature
to 40°C maximum.
Servomotor surface
dirty
Visual check
Clean dust and oil from
motor surface.
Servomotor
overheated
Overloaded Run under no load.
Reduce load or replace with
larger capacity servomotor.
Servomotor mounting
screws loose?
Tighten mounting screws.
Coupling not centered? Center coupling.
Incorrect mechanical
mounting
Coupling unbalanced? Balance coupling.
Bearing defective
Check noise and
vibration near bearing.
Consult your YET
representative if defective.
Abnormal noise
Machine causing
vibrations
Foreign object intrusion,
damage, or deformation
of sliding parts of
machine.
Consult with machine
manufacturer.
Speed reference
0V but servomotor
rotates.
Speed reference
voltage offset applied
—
Adjust reference offset.
Refer to sections 7.2.4 and
7.2.5

Alarm Name Description
A.02
Parameter Breakdown
*
EEPROM data of servo
amplifier is abnormal.
A.03
Main Circuit Encoder
Error
Detection data for power circuit
is abnormal.
A.04
Parameter Setting
Error*
The parameter setting is outside
the allowable setting range.
A.05
OFF OFF OFF OFF
Servomotor and
Amplifier
Combination Error
Servo amplifier and servomotor
capacities do no match each
other.
A.10
ON OFF OFF OFF
Overcurrent or Heat
Sink
Overheated
**
An overcurrent flowed through
the IGBT.
Heat sink of servo amplifier was
overheated.
A.30
Regeneration Error
Detected
•Regenerative circuit is faulty
•Regenerative resistor is faulty.
A.32
ON ON OFF OFF
Regenerative Overload
Regenerative energy exceeds
regenerative resistor capacity.
A.40
OFF OFF ON OFF
Overvoltage
Main circuit DC voltage is
excessively high.
* These alarms are not reset by the alarm reset signal (/ALM-RST). Eliminate the cause of the alarm and then turn
OFF the power supply to reset the alarms.
Note: OFF: Output transistor is OFF.
ON: Output transistor is ON.
**
This alarm display appears only within the range of 30W to 1kW.
