15 00 Servo Drive
Overheat The internal tempera-
ture of Servo Drive
exceeded the circuit
protection level. The ambient tempera-
ture of the Servo Drive
exceeded the specified
value. Improve the ambient temperature
and the cooling conditions of the
Servo Drive.
Overload Increase the setting of the accelera-
tion/deceleration time or stopping
time to lighten the load. Or,
increase the capacities of the Servo
Drive and the motor.
01 Motor Over-
heat Error The encoder detected
the temperature that
exceeded the protec-
tion level of motor. The temperature is high
around the motor. Adjust the temperature around the
motor to be within the range of the
operating temperature.
The motor is over-
loaded. Adjust the motor load ratio to be
within the specified range.
Encoder failure Replace the motor if this event
occurs repeatedly.
16 00 Overload
Error The load ratio of Servo
Drive or motor (4105-81
hex) exceeded 100%. Operation was contin-
ued for a long time with
high load. Take the following actions accord-
ing to conditions.
• Increase the set value of the
acceleration/deceleration time or
the stop time.
• Lighten the load.
• Adjust the gain or inertia ratio.
• If torque waveforms oscillate
excessively, adjust the system by
the tuning so that the oscillation
does not occur.
• Set the appropriate brake timing.
• Increase the capacities of the
Servo Drive and the motor.
There is incorrect wir-
ing of the motor cable or
a broken cable. • Connect the motor cable as
shown in the wiring diagram. If
the cable is broken, replace it. Or,
connect the motor cable and
encoder cable that are used
together to the same motor.
• Measure the voltage at the brake
terminal. If the brake is applied,
release it.
Increase in friction Check machine conditions and
remove the cause of the friction.
Error No.
