VF-S11 is the standard TOSHIBA drive incorporating  a wide range of useful functions for machinery and facilities in various industrial sectors and applications. The advanced sensorless vector control algorithm provides high torque throughout the speed ranges. Excellent performance, high level of flexibility and user-friendly features, the VF-S11 reveals the potential and future of inverters.

• Powerful Torque Control
  - 250% Torque at 1.0Hz
  - One step motor auto-tuning
  - 0.1% Speed Regulation on 60:1 Speed Range
  
  The VF-S11incorporates TOSHIBA's proprietary current vector calculation control system to generate starting torque of 1Hz -200% or more*. This provides sufficient leeway in applications that require large starting torque and ensures smooth operation in the regeneration area and in the motoring area. In addition, auto tuning and auto torque boost can be activated in a single step.

• Side-by-side installationmeans that you can further save space as two or more units can be installed in close proximity next to each other.

• All VF-S11 units are equipped with a high attenuation EMI/RF noise filter. Single phase and 500 class devices include filters that bring the drive into compliance with Class A group 1 to satisfy the CE EMC directive.*
  　
• Capacitors on the main circuit have been designed to have a life of 10 years*. In addition, the VF-S11 can be used in an ambient temperature of up to 60°C and demonstrates excellent environmental resistance.

• Fans, pumps, blowers, and air-conditioning equipment must be maintained on a regular basis. The VF-S11 monitors the expected replacement period of spare parts and outputs an alarm to serve as a rough guideline for when to perform maintenance.

• Integrated Modbus® and CANopen protocols are available as standard. Flexible, fully programmable I/O, as well as being highly expandable, the VFS11 uses a detachable type of control terminal board, which allows you to easily mount optionally available communication boards.

• The VF-S11 is the best in its class when it comes to environmental considerations. Equipped with energy savings modes, applications reach a higher level of efficiency.

• IP54 compliant structure protects contents from dust and harmful effects of water. Can be brought into IP55 by making wiring port watertight. IP54 version has built-in circuit breaker and self cooling structure.

• Compliance with global standards including CE, CSA and UL.
