Bihl+Wiedemann: Lenze Drives Are a Perfect Match for ASI-5

February 2, 2021

For many years, customers have enjoyed the benefits of AS-Interface for controlling Lenze Drives and frequency inverters. The free topology and cost-effective installation technology of ASi saves both time and money. Bihl+Wiedemann added to this perfect match with additional products like the ASi-5 self-configuring 8 I/O module (BWU4232). This module is ideal for the Lenze Smart Motor or other drives with binary control and four additional signals – either inputs or outputs.

This allows you to control two Lenze Smart motors with one 8 I/O module. The binary interface of the motor provides three digital inputs and one output – distributed over two M12 lines, which fits the module perfectly.

Flexible in use

Due to its flexibility, the ASi-5 self-configuring 8 I/O module works in other applications as well: For example, the IP20 version for a control station (pushbuttons and lights) in the control cabinet and the IP67 version for collecting sensors with either one or two switching signals per M12 socket.

High I/O density, precise diagnosis

Thanks to ASi-5, the 8-bit bidirectional process data are transmitted consistently in only 1.27 ms. Due to the high I/O density per ASi-5 module, the number of ASi addresses is greatly reduced. The channel-specific diagnosis in the module make it possible to detect a short circuit on the output or an overload of the sensor supply for each individual connection. Thanks to the cyclic diagnosis, errors can be quickly localized and eliminated. And in combination with our diagnostic software which provides you active assistance, troubleshooting becomes even easier.

All signals on a single line

In addition to controlling motors with AS-Interface you can transmit other standard or safety signals over the same network. This reduces the wiring effort and the associated costs.

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
