Corrective measures
Cause Corrective measures
1
Faulty amplifier control board or power
module
Replace servo amplifier.
2 Faulty servomotor encoder circuit Replace servomotor.
3 Effective torque exceeds rated torque
Monitoring torque generated by motor using
the estimated effective torque (Trms) to
check if effective torque is exceeding rated
torque.
Or, calculate effective torque of motor from
the load and operating conditions → If
effective torque is higher than rated torque,
review operating or load conditions, or
replace with larger capacity motor.
4
Incorrect combination of amplifier and
motor.
Check if motor code conforms to servomotor.
Correct if necessary.
5 Holding brake of servomotor is not released
Check brake wiring for errors. Replace
servomotor if brake wiring is found to be correct
(and voltage is applied as specified).
6
Incorrect wiring of U, V, W phases between
amplifier and motor
Check wrong wiring and correct it.
7
One or all of the U, V, W phase wirings
between amplifier and motor is
disconnected
Check wrong wiring and correct it.
8 Mechanical interference Review operating conditions and limit switch.
9
Encoder pulse number setting does not
meet motor
Make it meet encoder pulse number of motor.
Caution
In case of alarm cause #3, repeatedly turning the control
power OFF --> ON may cause the servomotor to bum.
After eliminating this above cause, turning off the power
supply, and sufficient time passes over (30 minutes or
more), reoperate.

Corrective Measures
Cause Corrective measures
1
Allowable regeneration power
of built-in regenerative resistor
is exceeded.
Load inertia is too large, or
conducted time (for one cycle)
is too short
Review the load inertia and the
operational pattern
Use an external regenerative resistor
module.
Smaller load inertia within specified
range
Increase deceleration time
Increase conducted time
2
Built-in regenerative resistor
module is specified, but faulty
wiring.
Check wrong wiring and correct it.
3
Though external regenerative
resistor module is specified,
wiring is incorrect.
Check wrong wiring and correct it.
4 Faulty regenerative resistor.
Replace servo amplifier if using built-in
regenerative resistor module.
Replace resistor if using external
regenerative resistor module.
5
Resistance value of external
regenerative resistor module is
too large
Change to resistor that meets
specification.
6
Input power voltage is over
specification.
Review input power voltage
7 Faulty amplifier control circuit Replace servo amplifier.
8
Though selecting “Using external
regenerative resistor (02)” in
Page 0E of System Parameter
Regenerative resistor selection, it
is not equipped.
Equip an external regenerative
resistor.
Specify “Regenerative resistor is not
connected”.

Caution
For the setting that internal or external regenerative resistor
is used, detect regenerative error if it is not actually
connected.
For the setting that regenerative resistor is not used,
regenerative error is not detected when it is actually
connected. In other words that may damage or bum the
amplifier and its peripheral circuit.

Corrective measures
Cause Corrective measures
1
Faulty internal circuit of Servo
Amplifier
Replace amplifier.
2 Regenerative power is too large
Review operational conditions
Use external regenerative resistor
3
Although regenerative power is
within specification, ambient
temperature of Servo Amplifier is
out of specification.
Review cooling method so that
temperature in control board is from
32°F (0℃) to 131°F (55℃).
4
Though regenerative power is
within specification, the cooling
fun in Servo Amplifier stops.
Check if the cooling fan in amplifier is
rotating. Replace the amplifier if fan is
not operating.
5
Regenerative power when
emergency stoppage was too
large.
Replace Amplifier
Review load condition
Caution
Detect the error by amplifier internal temperature regardless
of ambient temperature. If warning of amplifier ambient
temperature is detected, make sure to review the cooling
method in the control board.
