VFD expands Unitronics offerings to motion control

August 7, 2018 – Unitronics, a PLC manufacturer, has announced a new variable frequency drive (VFD) line to meet demand for motor and motion control solutions.

VFDs, also called inverters, optimize machine performance, save energy, and lower machine lifecycle costs across a range of applications, including packaging, conveyance and material handling, machining, pump and fan applications.

The new VFDs integrate with UniStream, Vision and Samba, the company’s existing lines of PLC + HMI all-in-one controllers.

Unitronics offers options for both single and three-phase VFDs from 0.4 kW and up to 110 kW. Features include EMC built-in filters, braking units, mounting options, sensorless vector and torque control, extended operating range for temperature, STO (Safe Torque Off), Modbus RTU fieldbus and heavy-duty overload capacity. The VFDs are also UL approved, TÜV SÜD Safety and CE Certified.

The addition of a VFD product line simplifies workflow by enabling customers to obtain VFDs, PLCs and HMIs from a single supplier, program them all in a single software, and receive support from the same team throughout a project. The company’s software enables the user to set up, configure and commission multiple VFDs, as well as to monitor and debug the VFD via online watch or Scope Trace graph. Users can also operate their VFD directly from the controller’s integrated HMI panel, allowing them to take advantage of the full-colour touchscreen. Through remote access, users can also monitor the VFD via the software, web server or a VNC connection.
