8.1 Periodic Inspections
8.1.1 Inspections
Periodic inspection of the following items is recommended.
[1] Are any of the screws on the terminal block loose? If loose, tighten them.
[2] Is any abnormal noise heard from the servo motor bearings or brake section?
[3] Are any of the cables damaged or cracked? If the cables move with the machine, periodically inspect the cables
according to the working conditions.
[4] Is the core of the load coupling shaft deviated?
8.1.2 Cleaning of Spindle Motor
If you continue to use the spindle motor with dirt such as oil mist and dust adhered, its cooling performance degrades
and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. In some
cases this may result in damage to the bearing or cooling fan. To ensure the cooling capability of the spindle motor's fan,
carry out periodical cleaning of the spindle motor and its cooling fan according to the following cleaning procedure.
Note that the spindle motor SJ-D Series and the spindle motor SJ-VL Series is used as an example in this procedure.
When cleaning the other spindle motors, carry it out based on this procedure.
WARNING
1. Before starting maintenance or inspections, turn the main circuit power and control power both OFF.
Wait at least fifteen minutes for the CHARGE lamp to turn OFF, and then using a tester, confirm that the input and output
voltage are zero. Failure to observe this could lead to electric shocks.
2. Inspections must be carried out by a qualified technician. Failure to observe this could lead to electric shocks. Contact
your nearest Mitsubishi branch or dealer for repairs and part replacement.
CAUTION
1. Never perform a megger test (measure the insulation resistance) of the drive unit.
Failure to observe this could lead to faults.
2. The user must never disassemble or modify this product.
CAUTION
Do not touch the motor for some time after turning OFF the power, as the motor remains at a high temperature.
This may lead to burns.
