ABB Industrial Drives, ACS800 Preventive Maintenance

ABB recommends regular preventive maintenance of AC drives to ensure maximum availability, minimum unscheduled repair costs, optimum performance and longevity throughout their lifetime. Driver preventive maintenance consists of annual driver inspections and component replacements according to a product-specific maintenance schedule.

Advantages

- Increased drive reliability

- Optimum maintenance costs and minimized repair costs

- Easy to plan maintenance budget

- Extended drive lifetime

- Genuine, factory-approved ABB spare parts

Service Content

The preventive maintenance service includes the labor and spare parts necessary to perform the maintenance work on site according to the maintenance schedule:

Visual check of the driver and environmental conditions

- Checking the connections

- Checking flat cables and fiber optic cables

- Functional control of the fan and cooling system

- ESD protected drive cleaning

- Checking the Emergency Stop circuit

- Unexpected work? checking the circuit

- Examination of error logs

- Control and saving of parameters

- Performing function tests of the drive under normal conditions

- Basic measurements of supply voltage

- Control of spare parts inventory

- Reforming redundant module capacitors

The drive preventive maintenance program is based on ABB's extensive knowledge and experience in AC drive manufacturing and maintenance for more than 30 years. Environmental and usage conditions are also taken into account. Preventive maintenance work is carried out on site by authorized and certified experts. When the maintenance work is finished and the checks are done, a detailed service report is provided with recommendations for further action.

In the maintenance calendar ?R? Information on pre-made preventive maintenance kits for component replacements marked with is available at www.abb.com/partsonline.
Preparations before preventive maintenance

The success of preventive maintenance depends on the information recorded. The more information provided by the end user, the more efficient the result.

ABB service personnel should be able to work comfortably on the drive during the predetermined downtime with the customer. Preventive maintenance must be planned well in advance to ensure that the required resources and spare parts are available.

Maintenance Schedule

According to ABB's experience, the probability of failure in devices containing electronic components such as drives increases with operating time. For drivers, this period is between 5-10 years. Although the main cause of failures is the aging of the components, the operating conditions are also an important factor. As a result of the failure of any component, power semiconductors and other components can be affected and damaged.

The maintenance schedule is a systematic and functional representation of the maintenance action to be performed for a particular drive type. This calendar was created based on extensive knowledge and experience in drive manufacturing and maintenance. Component suppliers' specifications have also been studied in detail. Environmental and working environment conditions of the driver should also be taken into consideration. Heavy operating conditions such as high temperature, humidity, pollution, and periodic overload significantly reduce the life of the drive components and shorten the maintenance and material replacement intervals.

Note ! Recommended service intervals and component replacements are valid for the operating conditions stipulated by ABB. ABB recommends that drive checks be carried out annually to keep drive reliability at the highest level and to ensure optimum performance.
