Powerful True Torque Control
- 250% Torque at 1.0Hz
- One-Step Motor Auto Tuning
- 0.1% Speed Regulation on 60:1 Speed Range
High Torque
Initial torque surpasses 1Hz-200%* at start up instantly from low speed. Smooth operation in the regeneration area and in the motoring area is possible through proprietary power vector control. Equipped with an energy savings mode, applications reach a higher level of efficiency.
In addition, you can activate auto tuning and auto torque boost in a single step.

Dynamic brake chopper transistor standard on all models
Easy Maintenance
A warning signal is output to the display panel when the electrolytic capacitors on the main circuit, the cooling fan or the control board reach the replacement period. This is a valuable indicator, which can be used as a maintenance guideline. The cooling fan is replaced easily, and the automatic on/off function provides extended product life. Furthermore, this is a long-
life inverter. Its main circuit capacitors are designed with a 10-year lifetime.* It is designed to be used in ambient temperatures up to 60˚C for maximum environmental resistance (with minimum current derating required).
*Ambient temperature: average yearly temperature of 40˚C. Output current: operating
24 hours per day for 365 days at 80% of the current rating.
Easy-to-Use
The S11ʼs design gives you the ability to apply power, connect a
motor and run right out of the box. It has an easy-to-use customer
terminal strip for integration into complicated applications, and
its small footprint and side-by-side mounting capabilities make
it an excellent OEM product.
Built-In EMI Noise Filter
The S11 is the best in its class when it comes to environmental
considerations. All 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.*

Compact
The S11 saves space with its reduced dimension compact design. Multiple units can be mounted side-by-side for high-density installation. The compact design does not hinder its capabilities. The high-level of functionality and user-friendly features of the S11 make it a top class inverter.
Communications
External communication modules are available with functionality
for multiple drive connectivity. Available protocols are Ethernet
TCP/IP, Ethernet IP, DeviceNet, Modbus Plus, Modbus RTU,
Metasys, Landis and Staefa, Profibus DP. These interfaces are
already used extensively on 7-Series and 9-Series Toshiba
inverters.
