ABB S-073N phase module in the ACS6000 system Medium voltage AC drive

ABB’s ACS 6000 medium voltage drive provides the optimum solution for applications where high power and maximum reliability is required. Since its introduction, the ACS 6000 has gained an excellent reputation for high quality and reliability. As a result ABB has worldwide one of the largest installed bases of medium voltage multidrives incorporating the latest technology.

ACS6000

ABB’s ACS 6000 is a modular drive designed for the most demanding single-motor or multi-motor applications. The optimum configuration for each application is reached by combining the standardized modules resulting in lower investment costs and a smaller footprint. The ACS 6000 is available with several different inverter modules in the power range from 3 to 13 MVA.

Key features

Powerful performance

Fast and accurate process control in combination with low energy consumption results in top performance. The motor control platform of the ACS 6000 is based on ABB’s awardwinning Direct Torque Control (DTC) technology. DTC provides the highest torque and speed performance ever achieved in medium voltage drives. As a result, control of the drive is immediate and smooth under all conditions.

Key product features

– Modular design for optimum configurations

– Common DC bus for single and multi-motor operation andminimized energy consumption

– Line Supply Unit (LSU) for two-quadrant operation with aconstant power factor of 0.95 over the whole speed range

– Active Rectifier Unit (ARU) for regeneration and power factorcorrection

– DTC control platform for exceptionally high torque anddynamic performance

– High level of personal safety and drive availability due tosuperior arc protection

High efficiency and reliability

The ACS 6000 uses a power semiconductor known as IGCT (Integrated Gate Commutated Thyristor), which is an ideal switch for high-power medium voltage applications. The use

of IGCTs results in low parts count, providing an efficient and reliable drive.

High availability

Maximum reliability and short repair time results in a drive with high availability.

Optimized energy flow

The common DC bus allows several motors to be connected to the same DC bus, providing an optimized energy flow.

The braking energy generated in one motor can be transferred to other inverters via the common DC bus without power consumption from the supply network. Due to the near unity power factor throughout the whole speed range the energy efficiency is optimal.

Optimum configuration

The modular design of the ACS 6000 allows the optimum configuration of any drive system. Each configuration, consisting of well-proven and certified modules, exactly fits the customer’s requirements.

Smooth system integration

The ACS 6000 integrates easily into the industrial environment because it can be optimally configured for single-motor and multi-motor applications without additional control equipment. The high power density and compact design and the drive’s communication abilities minimize the overall installation and operational costs. The drive can be connected to the network through one or several transformers depending on power and harmonics requirements. A transformerless solution is also available for certain applications.
