19. Amplifier Overheat
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
Reduce the ambient temperature to 55 [°C] or lower. (40
[°C] or lower temperatures are recommended for regular
operation.)
The ambient temperature exceeds
55 [°C].
Move heat generating bodies near the servo amplifier as
far away as possible.
Perform operation at a continuous load factor within 100%.
20. Encoder Overheat
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
Excessive ambient temperature
•
Reduce the ambient temperature of the servomotor to
40 [°C] or lower.
•
Remove shields interrupting heat radiation, if there
are any.
The effective torque exceeds the
rating.
Increase the cycle time and reduce the operation
frequency.
The main body of the encoder detects this alarm according to results of self-diagnosis.
21. Absolute Data Lost
[Display]
[Description of detected alarm]
The temperature of the servo amplifier has exceeded the
allowable limit.
The encoder inside the servomotor may be overheated.
The absolute data of the encoder is lost.
dL1: Battery voltage drop, broken encoder cable, loss of
multi-rotation data
dL2: Multi-turn data fault in encoder
dL3: Detection at power-on after an ET alarm
