Overview

Compact Design

Distinguishes the S15 as one of the smallest drives available in the industry. Its compact design allows installation in tight spaces, providing users with more valuable real estate for running applications.

 

Easy Installation and Programming

Install and program the S15 drive with minimal downtime, making it efficient and user-friendly. DIN Rail Kits allow for easy drive mounting onto a pre-existing DIN inside a cabinet or on a panel.

 

Power the Control Section with 24 VDC

+SU Terminal allows programming the drive without needing 230 V, 460 V, or 600 V three-phase power, simplifying the setup process.

 

Tough Environment

Engineered to endure extreme environments, the S15 can operate at temperatures up to 122°F (50°C) without derating. It can also be configured to function at temperatures exceeding 122°F (50°C) with a de-rate.

 

Superior Control

Ultimate application flexibility with Toshiba’s advanced vector-control algorithm, achieving 0.1% sensor-less speed regulation. Energy-saving, user-selectable V/Hz patterns make the S15 a smart choice for any application.

 

Heavy Duty Performance

Sets the S15 apart from the competition with one of the most robust micro-drive overload ratings of 110% full-load amp rating for continuous operation and 150% for up to one minute.

Insulated Bearings

  • An electric motor operating on an adjustable speed drive is at risk for premature bearing failure caused by stray currents. Experience indicates using insulated bearings on both ends of the motors is the most effective way to protect the motor from destructive currents. A high level of bearing protection is especially beneficial in applications where motor maintenance and replacement are difficult.
  • Extended Horsepower Capability

  • Extended horsepower capability allows a smaller motor to run at a higher horsepower than its baseline depending on the application requirements. This provides motor users potential cost savings while achieving the same motor performance.
  • Insulation with Wide Thermal Capability

  • Critical cooling motors utilize many Class H insulation materials in its winding designs, which provides increased thermal protection. These motors operate with a very low temperature rise at rated conditions, giving them a wide thermal margin and extended motor life.
  • Low Vibration

  • A vibration level exceeding NEMA MG1 requirements provides stability and durability by prolonging motor and bearing life and helping to reduce downtime.
