Danfoss VLT 5000 Flux

The VLT 5000 Flux is an extension of the VLT 5000 series. Full torque control under acceleration as well as very accurate speed control even at low speed or standstill can be obtained. Flux control is the future technology for high performance drives.  It provides excellent dynamics and accuracy, suited for drives systems with and without feedback.  The VLT 5000 Flux features automatic acquisition of motor Danfoss VLT 5000 Flux Syncposequivalent circuit diagram and provides 100% control of flux and torque, taking the system inertia into account. The VLT 5000 Flux provides up to 60% torque from 0 to rated speed.


SyncPos makes VLT 5000 Flux highly programmable and provides synchronising and positioning.

Flux Principle

The Danfoss VLT 5000 Flux PrinciplePlug in TerminalsThe flux principle provides high shaft performance (torque control about 3 ms), excellent synchronising also at very low speed. Speed accuracy with open loop +/- 0.5% (8 rpm) and with
closed loop +/0.001% (0.02 rpm). Flux control provides 180% acceleration torque (0.5 sec), 160% holding torque at 0 RPM in 60 sec (closed loop). The accuracy of torque control is : closed loop +/- 10%.
