The all-rounder



The VF-S15 is convincing in functionality and precision in the mid-range performance class. With its constant response time, the dual rating operation and many functions for easy operation and configuration the VF-S15 becomes the first choice in most applications within the power range from 0.25 kW up to 18.5 kW. Many common field bus interfaces are available as plug-in hardware modules.
Depending on the model, the premium equipment of the VF-S15PL-W1 enhances the application range to demanding applications with respect to safety functions, energy efficiency and drive control. It includes a safety function STO, integrated PLC functions (Logic Sequence), servo lock, PM motor drive capability and an application software package for quick and easy configuration.
