You can now also control NORDAC FLEX frequency inverters from NORD DRIVESYSTEMS via ASi-5 – and take advantage from greatly reduced costs and easy commissioning.

The new ASi-5 motor module for NORDAC FLEX (BWU4371) makes use of ASi-5 to change process control ramps and speed cyclically, thereby enabling extremely quick adjustment. An optimized process data image is provided for this purpose. Motor feedback is also very comprehensive thanks to ASi-5. This is because in addition to the error flags, even the current consumption of the motor and addtional information are available for evaluation in the cyclic input data. The additional four digital inputs and two digital outputs enable cost-effective connection of further sensors and actuators to the module.

The ASi-5 motor module for NORDAC FLEX (BWU4371) will of course allow you to benefit from the well-known ASi advantages, such as drastically reduced wiring complexity. Yet another advantage is gained from the use of our Bihl+Wiedemann Software Suite: Once you have configured an ASi-5 motor module and stored the NORDAC parameters, you can simply copy this information to numerous other ASi-5 motor modules. During commissioning, all motor parameters are downloaded automatically. Parameterization also takes place automatically when motors and motor modules are replaced. This spares you a lot of time and costs avoiding at the same time possible parameterization errors.
