Danfoss Drives (Milwaukee, WI) introduced the VACON 20 AC drive that features built-in PLC functionality. It is available in all common voltages (110- 600V), and a power range up to 18.5 kW/25 HP. The built-in RS-485 interface offers a serial control interface for the drive. With optional modules, the drive can be connected to almost any communication system including CANOpen, Fieldbus, DeviceNet, and Profibus DP. Features include accessible terminals, built-in DIN rail mounting, and the MCA parameter-copying tool that can clone settings without main power in the drive. Users can build their own control logic in the drive, and utilize unused I/O of the drive for performing other machine-related tasks. In addition, the parameter list can be freely modified, and application-specific parameter sets and default settings can be created.
