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