Indicators
Error
Status when error
occurs
Cause of error Countermeasure
Operated while the holding brake was
engaged. Measure the voltage at the brake
terminals and release the brake.
The ambient Servo Driver
temperature exceeds 55°C.
There is a problem with the Servo
Driver’s installation environment, such
as the installation direction, spacing
between Units, or surroundings.
Review the installation conditions
so that the Servo Driver’s
ambient temperature is below
55°C.
Occurs during normal
operation.
(Continued)
The Servo Driver is faulty. Replace the Servo Driver.
Re-evaluate the load conditions.

Overload
(Continued)
Occurs when the
servo is turned OFF. The Servomotor did not stop even
though 3 seconds passed after the
servo was turned OFF.
Check whether an external force
is rotating the Servomotor.
The encoder cable is wired incorrectly
or the connector is loose. Check the wiring.
Noise is infiltrating the cable because
the encoder cable does not meet
specifications.
Use an encoder cable with
twisted-pair wires or shielded
twisted-pair wires that are at least
0.12 mm
2
(26 AWG).
Noise is infiltrating the encoder cable
because the cable is too long. Shorten the encoder cable to less
than 20 m.
The encoder cable is broken. Replace the encoder cable.

error Occurs when the
power is turned ON or
during operation.
Faulty encoder
Replace the Servomotor.
The power supply voltage exceeded
the allowed range. Keep the power supply voltage
within the allowed range.
The Servo Driver’s power was turned
ON again before it was completely
turned OFF. Wait until the REF Indicator is
OFF before turning ON the power
supply again.
Occurs when the
power is turned ON.
The Servo Driver is faulty. Replace the Servo Driver.
There was a large voltage change in
the main circuit power supply. Keep the power supply voltage
within the allowed range.
The motor is rotating at high speed
and the load inertia is too large. Re-evaluate the load and
operating conditions.
An external Regeneration Resistance
Unit is not connected or the wrong
external Regeneration Resistor was
selected.
Calculate the regenerative
energy, and connect an external
Regeneration Resistance Unit or
Regeneration Resistor with
sufficient capacity.
