Product information ABB ACS800-01-0040-3+P901  :

Protecting the motor insulation and bearings The output of the drive comprises – regardless of output frequency – pulses of approximately 1.35 times the equivalent mains network voltage with a very short rise time. This is the case with all drives employing modern IGBT inverter technology. The voltage of the pulses can be almost double at the motor terminals, depending on the attenuation and reflection properties of the motor cable and the terminals.

This in turn can cause additional stress on the motor and motor cable insulation. Modern variable speed drives with their fast rising voltage pulses and high switching frequencies can generate current pulses that flow through the motor bearings, which can gradually erode the bearing races and rolling elements. The stress on motor insulation can be avoided by using optional ABB du/dt filters. du/dt filters also reduce bearing currents. To avoid damage to motor bearings, the cables must be selected and installed according to the instructions given in the hardware manual. In addition, insulated Nend (non-driven end) bearings and output filters from ABB must be used according to the following table. Two types of filters are used individually or in combinations:

• optional du/dt filter (protects motor insulation system and reduces bearing currents).
• common mode filter (mainly reduces bearing currents).

A full selection of both mechanical and electrical installation kits is available for liquid-cooled ACS800 frequency converter modules. These make cabinet installation into RITTAL TS8 cabinets efficient and easy. A large variety of support material such as dimensional drawings and circuit diagrams is also available for making cabinet assembly, planning and implementation as straightforward and rapid as possible. It is also possible to use optional installation racks instead of cabinets. Installation racks are a compact and cost efficient way to assemble a full liquid-cooled ACS800 frequency converter drive system inside a closed environment such as, for example, a container without an existing air-conditioning system.
