Protective function Causes Measures
Main Sub
15 0 Over-heat protection The temperature of the radiator and power
element of the driver module exceeded the
specified value. Check the operating temperature range of
the driver module.
1) Ambient temperature has risen over
the specified temperature. 1) Improve the ambient temperature and
cooling condition.
2) Use with an overload. 2) Increase the capacity of the driver
module and motor. Set up longer
acceleration/ deceleration time. Lower
the load.
3) Failure of driver module.
(Failure of the temperature detection
circuit) 3) Replace the driver module.
1 Encoder over-heat error
protection The driver module detected that the
temperature of each axis encoder exceeded
the encoder overheat error level. Check the operating temperature range of
the servo motor.
1) The ambient temperature of the driver
module is high. 1) Improve the ambient temperature and
cooling conditions of the servo motor.
2) Use with overload. 2) I Increase the capacity of the driver
module module and motor.
Set a longer acceleration/deceleration
time.
Reduce the load.
3) Failure of driver module.
(Failure of the temperature detection
circuit in encoder) 3) Replace the driver module.
