The Revolution



The high-performance TOSHIBA VF-AS3 achieves high speed/real time network communication via embedded Ethernet without any optional devices, ready to meet the requirement of modern automation with IoT and Industry 4.0.

Also, VF-AS3 with TOSHIBA excellent motor control technology and hardware design helps for all your applications and is available in the power range from 0,4 kW to 315 kW.

The TOSHIBA VF-AS3 improve effectivity and productivity of plant and machinery. The high torque-precision and the excellent dynamic, both with and without speed feedback, effect a superior motor control performance, associated with substantially less energy consumption and extended life cycle of the plant. Furthermore, diverse safety functions are modular realisable.
The safety standard with STO (Safe Torque Off) function, 2-channel and other safety functions optional, ensures the reliable cut-off in emergency situations according to IEC61800-5-2.

The integrated Web-Server enable the user a system-independent access to all data and parameters of the application and provide in addition the complete possibility for optimisation and fault analysis.
The built-in dual DC reactor suppresses harmonic current and improves power factor. VF-AS3 complies with IEC61000-3-12 and achieves total harmonic distortion (THDi) ? 48% without external reactor (480V Class only). The integrated EMC filter is designed according to IEC61800-3 category C2 / C3 (400V-class).

Over the complete power range up to 90 kW these inverters are also available with protection class IP54/55.
