New-generation compact inverter
May 2001
Motion Control & Drives
This powerful unit is compact in size, but offers excellent performance from its sensorless flux vector control, combined with easy installation and setting. The drive inherently satisfies CE certification requirements (as it has an integral EMC filter). Panel space saving is significant and there is less wiring during installation.
Toshiba has retained the simple potentiometer speed setting it pioneered some time ago with the VF-S7, but the adjustment knob is larger and clearer allowing immediate and easy operation. The drive has been designed for a global marketplace and meets with all standards including UL/CUL, CE and C-tick. Input and output phase failure is automatically detected by the drive. Unusually for a small drive of its type, the new VF-S9 has four automatic setting functions for acceleration/deceleration, torque mode, v/f control mode and terminal assignment. Other features include a wide voltage tolerance band, from 380-500 V ±10% and a switchable control logic interface (sink/source). It offers programmable terminal functions for assigning suitable functions to each terminal. This is a drive that really can be fitted straight out of the box.
The unit has been designed with panel builders very much in mind, as the inverters can fit neatly alongside each other for multiple drive arrangements, for example, installing five units of VFS9-2007P side by side requires only 60% of the area for conventional inverters. The VF-S9 can also be DIN rail-mounted for the single-phase versions from 200 W up to 0,75 kW.
Optional extras include communications functions (RS232C/RS485), IP40/IP54 kits and an extended parameter writer for remote programming of the drives.
The range spans 200 W up to 2,2 kW in single-phase 200 V class, from 200 W to 1,5 kW in three-phase 200 V class and from 0,75 to 15 kW in three-phase 400 V class. The smallest 200 W drives measure just 105 mm wide x 130 mm high x 139 mm deep, while the largest 15 kW version still only measures 245 mm wide x 330 mm high x 195 mm deep.
