Emotron VFB/VFX is a range of high performing frequency inverters designed for controlling asynchronous motors over a wide speed and torque range. Typical applications include centrifuges, cranes, elevators, saws, winders and milling machines. Full control with less equipment The direct torque control gives you full speed and/or torque control without encoder feedback. When using VFB/VFX you eliminate the need for brake choppers and resistors that often are used in industrial applications. For e.g. cranes, you will have complete control of hoist and grab without external plc.
Protects your machines and processes The built-in load monitor protects your machines and processes from over- and underload. Thus you can avoid expensive breakdowns and production downtime caused by e.g. jammed mills or saws. The load monitor has the same functions as the Emotron EL-FI M20 Shaft Power Monitor.
Everything you need
- Display of frequency, current, torque, voltage, power and process status in clear text
Complete motor protection Protection of mains failures 4 parameter sets Different ramp times up to pre-set minimum frequency Application functions
Vector braking Comparators and logic functions Functions dedicated for cranes Selectable alarm and warning signals at any frequency
VFB/VFX is avaialble in eight physical sizes
- 4-750 A
- Motor voltage:400 or 500 VAC
- VFB, 4-16 A, IP 20 narrow size
- VFX, 18- 175 A, IP 20 or IP 54
- VFX, 210- 750 A, IP 20 and IP 54 in cabinets
