ABB integrates position control in ACS880 drives

ABB is integrating positioning control within its ACS880 variable speed drives to allow operators to meet motion system demands without the need of an external controller

Embedding position control inside the drive minimises machine engineering and installation work, and removes the need for additional equipment and lowers costs.

Traditionally, separate devices are used for position control and speed and torque. Position control is implemented using a motion controller with specific tools, user interfaces and programming languages. The power range of these separate controllers are typically limited to under 20kW depending on the manufacturer.

The ACS880 with embedded position control offers an alternative solution and a power range up to 5,600kW. It features several pre-programmed functions, including homing modes, absolute and relative positioning, profiled positioning, position synchronising and fast position latching. The ACS880 also offers encoderless position capabilities and regenerative solutions.

The motion functions are available through a simple parameter interface. Modification and extension of the functions are done by common IEC61131 programming using PLC Open motion blocks. The ACS880 supports almost any type of motor, feedback device and communication protocol.

The ACS880 drives are suitable for a variety of applications and engineered to perform in harsh environments, including mining. Tuomo Tarula, global product management manager, drives at ABB, said: "These drives have been successfully tested in numerous motion control applications, including stacker cranes, metal presses, sorting and packaging lines, rotary tables and cutting systems. These tests have proven the drives' high performance and flexibility."

The ACS880 platform enables the same product family to be used across the whole production line regardless of whether there is a need for positioning, speed or torque control. This means less training, tools and spare parts are required.
