7 Maintenance
7.1 Routine Maintenance
Many factors such as ambient temperature, humidity, smog, internal component aging will give rise to the occurrence of
potential faults. Therefore, it is necessary to conduct routine and periodic maintenance during storage or using of the
driver.
When the driver operates normally, please check if there are the following items:
1)
abnormal sound or vibration of the motor;
2)
abnormal heat producing from the driver or motor;
3)
high ambient temperature;
4)
whether the load current is as usual;
5)
whether the cooling fan of the driver runs normally.
7.2 Periodic Maintenance
To maintain a long-term normal operation, it is necessary to conduct periodic maintenance according to the working life
of internal electronic components. The working life varies with the operation condition. The following table is for
reference.
Part
Normal working life
Cooling fan
2~3 years
Electrolytic capacitor
4~5 years
PCB
5~8 years
You should check the driver every 3 months or 6 months according to the actual environment, thus could lower fault risks
