The VLT® Positioning Controller is user-friendly, enabling set-up of all parameters via the VLT® Automation-Drive Local Control Panel or via the VLT®set-upsoftwareMCT10.

AstheMCO351isastandardproductwith fixed functional properties, no additional application programming is required.

The Positioning Controller can handle most positioning applications with vertical as well as horizontal move-ments.

The option is mainly suited for appli-cations with an overall control system, for example a PLC.

Positioningontheuser’stermsThe technology behind the Position-ing Controller option offers a host of user-friendly benefits for positioning applications in many industries, like:

• Warehouses• Ice cream manufacturers• Bakeries• Production assembly lines• Distribution centres• Foodandbeverageprocessing

The MCO 351 Posi-tioning Controller option is fully inte-grated in the VLT® AutomationDrive. No additional wiring is required.
