Regular maintenance
Depending on the usage environment, the user can perform regular routine inspections of the drive
controller within 3-6 months to eliminate potential hazards and ensure long-term high performance
and stable operation of the equipment.
The inspection contents are as follows:
•
The control terminal is not loosened. If it is loose, it can be tightened with a suitable torque;
• The power terminals are in firm contact and there are no signs of overheating at the copper bars or
cable connections;
• Power cable, control cable for damage, especially for the skin that is in contact with the metal
surface;
•
The wire nose insulation wrap of the power cable and control signal wire does not fall off or rupture;
•
For dust cleaning on the circuit board and on the air duct, it is best to use a vacuum cleaner.
Note:
1. The drive controller has passed the pressure test before leaving the factory. The user does not need to
carry out the test. Otherwise, it will be damaged if the test is improper.
2. If the insulation test is performed on motor, the U / V / W terminal of the drive controller must be
disconnected and the motor tested separately, otherwise the drive controller will be damaged.
3. The long-term storaged drive controller must conduct a power-on experiment within 2 years. Use the
voltage regulator to slowly increase the input voltage of the driver to the rated value, and energize for at
least 5 hours.
