ABB integrates position control in variable speed drives
Published by Lucy Stewardson,
ABB has announced that it has embedded position control into its ACS880 variable speed drives, with the aim of reducing costs and simplifying machine building. The integrated position control within the speed drives allows operators to meet motion system demands without the need for an external controller.
With position control embedded inside the drive, machine engineering and installation work is minimised, the need for additional equipment removed, and costs lowered.
Separate devices are traditionally used for position control, speed, and torque. However, for the company, position control is implemented using a motion controller with specific tools, user interfaces, and programming languages. These separate controllers are typically limited to a power range of under 20 kW, depending on the manufacturer.
The ACS880 offers an alternative solution and power range up to 5600 kW. Several pre-programmed functions are featured, including homing modes, absolute and relative positioning, profiled positioning, position synchronising, and fast position latching. Encoderless position capabilities and regenerative solutions are also offered.
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. Almost any type of motor, feedback device, and communication protocol are supported.
“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,” said Tuomo Tarula, Global Product Management Manager of drives at ABB. “These tests have proven the drives’ high performance and flexibility.”
ABB is a technology leader in power grids, electrification products, industrial automation, and robotics and motion.
