28. Er.650: Heatsink overheat
Cause:
•
The power module of the servo drive is higher than the overtemperature protection level.
Cause Conrming Method Corrective Action
1. The ambient
temperature is too high.
•
Measure the ambient temperature.
Improve the cooling conditions
to reduce the ambient
temperature.
2. The servo drive is
powered off and powered
on several times to reset
the overload fault.
•
View the fault records.
Set H0B-33 and view H0B-34, and
check whether the overload fault
(Er.610, Er.620, Er.630, Er.650,
Er.909, Er.920, Er.922) occurs.
Change the fault reset method.
After the overload occurs,
wait 30s and then perform
the reset operation. Increase
the capacity of the servo
drive and motor, increase the
acceleration/deceleration time,
and reduce the load.
3. The fan is damaged.
•
Observe whether the fan works
during running.
Replace the servo drive.
4. The installation
direction and clearance
of the servo drive are
improper.
•
Check whether the installation of the
servo drive is proper.
Install the servo drive according
to the mounting requirements.
5. The servo drive is
faulty.
•
Power off the servo drive, restart
it after 5 minutes. The fault still
remains.
Replace the servo drive.
29. Er.740: Encoder interference
Cause:
•
The Z signal of the encoder suffers interference, resulting in too large change of
corresponding electrical angle of the Z signal.
Cause Conrming Method Possible Solution
1. The encoder wiring is
incorrect.
•
Check the encoder wiring.
Connect the encoder cable
correctly.
2. The encoder cable
becomes loose.
•
Check whether the on-site vibration is
too large, which loosens the encoder
cable and even damages the encoder.
Re-connect the encoder
cable securely.
