• Toshiba’s Proprietary Windows®-Based ASD Pro Software is available at no additional cost. This easy-to-use software is designed to provide a full range of programming and monitoring tools for all Toshiba low voltage drives, including the S15. ASD Pro offers parameter reading, trending, and logging features that allow the user to save and transfer parameters and export data and graphs to an electronic file. Parameter groups and trending data can be easily converted into spreadsheets or graphs for field and validation reports.

• VF-S15’s 'Easy' Key is a configurable key that simplifies startup and operation. The
  easy key quickly accesses commonly changed parameters. In addition, the easy key can also function as a simple local/remote key for easy operation switching.

• Easy Maintenance
  Monitor number of starting: Displaying number of starting and output the alarm signal are helpful for maintenance.
  Details on history trip records: Output current, input voltage etc, a monitor to identify the cause of the problem and help to find countermeasures. VF-S15 can keep memories of the last eight trips even after resetting.

• The VF-S15 is one of the smallest drives offered in the industry. The compact design allows the unit to be installed in areas with limited space, allowing users more space for running applications.
