Routine maintenance
Routine maintenance shall be carried out during regular operation of the driver to guarantee excellent operating environment; and
record daily operation data, parameter setting data, parameter changing and so on, establish and improve equipment application
file.
Through routine maintenance and inspection, various abnormal situations may be found timely and find out causes, and eliminate
hidden fault, ensure normal operation of equipment, and prolong service life of the driver.

Regular maintenance
To eliminate hidden fault, and guarantee long term table operation of high performance, user shall carry out a regular inspection to
the driver every 3~6 months or shorter interval according to the service environment.
Regular inspection content
1. The connector is loose or not;
2. Check main circuit terminals for poor contact, and copper row connection for mark of overheat;
3. Check power cable, control cable for damage, especially cutting mark on skin which in contact with metal surface;
4. Check insulation binder of power cable nose for falling off;
5. Clean dust on printed circuit board and air passage completely. It is best to use the cleaner;
6. Before insulation test to the driver, all connections between driver, power supply and motor, and short all of main circuit input and
output terminals with wire reliably, and then test against ground.
