– A standard PROFIBUS or PROFINET interface and various analog and digital
interfaces allow them to be easily integrated into automation solutions.
– Vector control ensures that they fulfill the most exacting requirements regarding the
accuracy and dynamic response of drives.
– Individual modules and power components can be replaced quickly and easily, which
ensures a higher level of plant availability.
– The motor-side inverters are coupled via the common DC link and allow energy to be
exchanged between motors that are motoring and generating. This means that energy
is saved, there is less load on the supply infeed and line harmonics are reduced.
– The supply infeed is generally only dimensioned for the maximum motor power
required / maximum motor current and not the sum of the energy requirements of the
Motor Modules connected to the DC link. For example, for conveyor systems or
engine test stands with Motor Modules that are simultaneously in the motoring and
generating modes, this frequently results in smaller supply infeeds.
– Simple commissioning thanks to the menu-driven "STARTER" commissioning tool.
– Optional menu-prompted AOP30 advanced operator panel for clear and user-friendly
drive monitoring / diagnostics, commissioning, and operation using a user-friendly,
backlit graphic LCD for plain-text display and a bar-type display of process variables.
– All device modules are easily accessible, which makes them extremely service
friendly.
– The converters are exceptionally quiet and compact thanks to state-of-the-art IGBT
power semiconductors and an innovative cooling concept.
