Another attraction is that dedicated motion controls typically have a maximum power rating of around 20kW. The ACS880 with embedded position control offers a power range up to 5.6MW, as well as regenerative and encoderless positioning capabilities. The drives support most motor, feedback and communications protocols.
The motion control capabilities include pre-programmed functions such as homing modes, absolute and relative positioning, profiled positioning, position synchronising and fast position latching. The motion functions are available through a simple parameter interface. They can be modified and extended using PLCopen motion blocks based on IEC 61131.
The VSDs’ motion control capabilities have been tested in a variety of applications including cranes, presses, rotary tables, and sorting and packaging systems. “These tests have proven the drives’ high performance and flexibility,” reports ABB’s global product manager for drives, Tuomo Tarula.
