Servo drives enhanced by real-time communication via Ethernet
B&R's Acopos servo drives have seen wide industrial application, such as in packaging and material handling for textile and plastic manufacturing.
Acopos bus-capable servo drives from B&R Industrial Automation Corp. now offer the power range of 400 W to 64 kW for machine manufacturing. An Ethernet Powerlink connection allows operation of these drives with up to 240 motion axes on one line using the same network. The company also states that Ethernet Powerlink is the only network currently on the market that provides real-time communication for servo drives. When using multiplex operation to control the motion axes, 200e, to support system commissioning, motor and junction temperatures and current and lag error data sampling are supported. These data are also useful by the human-machine interface associated with the drive.
Acopos servo drives work with various standard motor types, including synchronous and asynchronous (induction) motors—with or without a feedback device—as well as linear and direct-drive motors.
