Chapter 6 Inspection, Maintenance and Warranty
6.1 Inspection
Spindle drives consist of semiconductor devices, passive electronics, and motion devices, and all these devices have a service life. Even
under normal operating conditions, some of the devices may change their characteristics or fail if their service life is exceeded. To prevent this
kind of failure, preventive inspection and maintenance such as daily inspection, periodic inspection, and device replacement must be performed.
It is recommended that inspection be performed every 3~4 months after the machine is installed.
●
Daily inspection: to avoid damage to the spindle drive and shortened service life, please check the following items daily.
Item
Inspection content
Solution
Power
supply
Check whether the supply voltage meets the requirements and whether there is
a lack of phase supply.
Solve by nameplate.
Surroundings
Check whether the installation environment meets the requirements.
Identify the source and address it properly.
Cooling
system
Check whether there is abnormal heat and discoloration on the spindle drive
and motor, and the working condition of cooling fan.
Confirm if there is overload, whether the heat
sink of the spindle drive is dirty, or the fan is
blocked. Tighten the screws.
Motor
Check whether there is abnormal vibration and abnormal sound of the motor.
Fasten mechanical and electrical connections
and lubricate mechanical parts.
Load
condition
Check whether the spindle drive output current is higher than the motor or
spindle drive rating for a certain period.
Verify that no overload has occurred and that
the spindle drive is correctly selected.

●
Periodic inspection: generally, it is appropriate to conduct periodic inspection every 3 to 4 months, but in actual cases, please inspect based on
the actual usage and working environment of each machine.

Solution
Overall
Insulation resistance check; environmental check.
Fasten and replace defective parts; clean and
improve the working environment.
Electrical
connection
