Dual Rating S1 is the new simple and easy to use inverter with top performance. Targeting for OEM equipment markets, mainly covering general applications like packaging, winding, Fan & Pump and many others. Product Features J Supports SVC control J Enables high precision of speed torque control and fast speed response J Integrates safety function-STO (Safe Torque OFF, SIL2) J The unique I/F control is very suitable at low speed with high torque requirements J The transition from rotating state to dc braking is very smooth. The current impact is small, and the current response of dc braking...

Excellent performance at "Catch-on-the-Fly" The S1 is very suitable for applications where large flywheel masses continue to run for a very long time after the power supply has been interrupted. These are for example applications with large fans or centrifuges. S1 detects the remaining speed and catches the motor at the correct position to accelerate back to the intended speed.

Dual Rating (4kW – 110kW) S1-IP55: Well equipped for decentralized drive applications with the robust S1 in high protection class. Many applications require that the inverter can be used in close proximity to the motor. A high protection class is therefore essential. In applications such as overhead air vents or agitators in the activated sludge tanks of sewage treatment plants as well as many other applications, it is often a mandatory requirement to be able to install the inverter in a harsh environment threatened by dust or moisture. The S1 in IP55 version offers this in an efficient...
