Drive solutions for Lenze

On this page, we present our ASi-3 and ASi-5 drive solutions for Lenze. All modules are plug-and-play solutions with pin assignments adapted to the respective Lenze drive. We currently provide modules for the following drives:


  • Lenze Smart Motor
  • Lenze i550 IO-Link 

Please contact us if the drive you are looking for is not listed here. Here you will find detailed information about the advantages of our AS-Interface drive solutions.


Here you will find the product overview of our drive solutions for Lenze Smart motors.  


To the product overview

ASi-3 Modules for Lenze Smart Motors

Your advantages at a glance

  • Remote installation, easy maintenance
  • Reliable use, even in extreme temperatures of up to -30 °C
  • Connections for up to 3 sensors in one module 
  • Can control up to 5 speeds
  • Simple connection of the Lenze Smart motor via M12 sockets or pre-assembled cables
  • Transmission of standard signals and safety signals on the same cable
  • Optimum connection to the control system via all popular fieldbus systems
  • Different module designs are available for the control system of the Lenze Smart motor depending on the desired method of installation

ASi-5 Self-Configuring Module for Lenze Smart Motors

The ASi-5 Self-Configuring 8 I/O Module (BWU4232) is perfectly suited for the Lenze Smart motor or other drives with a binary interface. You can control two Lenze Smart motors using one 8-I/O module. That is because the binary connection of the motor allows for three digital inputs and one output – distributed over two M12 cables.


Your advantages at a glance

  • ASi-5 transmits the 8-bit bidirectional process data consistently in just 1.27 ms
  • Thanks to the high I/O density per ASi-5 module, ASi addresses are greatly reduced
  • The detailed channel-specific diagnostics enable individual detection of an output short circuit or overload of the sensor supply at each connection
  • Errors can be quickly localized and rectified by means of cyclic diagnostics
  • Combined with Bihl+Wiedemann diagnostic software, system troubleshooting is made even easier through active assistance features
  • Status of outputs individually readable
  • Cost-efficient digital outputs
  • All signals on a single cable

that can be used as inputs or outputs.

ASi-5 IO-Link Modules for Lenze i550

The decentralized Lenze i550 protect (IP66) frequency inverter can be easily integrated into ASi-5 with our compact active distributor (BWU4088), whereas our IO-Link Master in IP20 (BWU3843) matches perfectly the i550 control cabinet inverter. By integrating the inverters in ASi, you immediately benefit from all the advantages: easy installation, high flexibility, and low costs with maximum functionality.


Your advantages at a glance

  • ASi-5 transfers the 12 bytes of process data in only 2.54 ms and is comparable to the Lenze PROFINET data image
  • Simple parameterization of the frequency inverters through the integrated IODD
  • Automatic configuration and commissioning of replacement devices
  • Extensive diagnostic capabilities of the i550 enable predictive maintenance. They are made available by the ASi-5/ASi-3 gateway, e.g., via OPC UA.
  • Monitoring of operating time, utilization, controller deviation and heat sink temperature e.g. via OPC UA.

Fig.: Our broad product portfolio enables the implementation of a wide range of application scenarios. The example in the middle shows how one motor is simultaneously detected with an infra-red distance sensor in the ASi-5 system via the Lenze frequency inverter. This is made possible by our BWU4088 IO-Link drive solution. Here you find further information about all IO-Link solutions by Bihl+Wiedemann.
