Integration of Lenze servomotors with Siemens S120 drives: Tips for Resolver and Servo Parameter Configuration

Question:

Has anyone successfully integrated Lenze servomotors with Siemens S120 drives? Any tips or recommendations for configuring resolver and servo parameters? Specifically, we are working with Siemens CU310-2 PN 6SL3040-1LA01-0AA0 and Siemens PM240-2 6SL3210-1PE31-1AL0 drives. The Lenze motors in question are the MDFQARS112-22 with resolver IDNR00397002 and the GFQBT112-24 with resolver IDNR00397002. These resolvers are either installed on or inside the motor.

Could you please provide the specifications for those two motors? Thank you.

After conducting a quick search, I was unable to locate the specifications for the motor or resolver I needed. In the past, I have successfully used the Siemens S120 to control obsolete resolver-based servos. To determine the specs for the motor, I required the Siemens SMC20 module (6SL3055-0AA00-5AA3) to input the necessary information into the S120.

To ensure accuracy, please verify the servomotor data on the Lenze website at www.lenze.com. The MDFQA asynchronous servo motors can be found at https://www.lenze-com.ru/content/files/MCA-MCS-MQA-MDxKS-MDFQA__Servo%20motors__v3-0__EN.pdf, where you can access the operating instructions.

When considering Lenze motors, they can be likened to Siemens 1PH7/8 motors. Operating these motors should not pose any issues, especially since your motor is asynchronous. To ensure compatibility, make sure to obtain the right SMC for the encoder.

In order to set up a resolver, it is necessary to use an SMC10 module instead of an SMC20.

I've actually had some firsthand experience with this. Integrating Lenze motors with Siemens S120 drives mostly relies on configuring the drive to recognize the Lenze motor parameters, and pay special attention to the resolver configuration - it's all about the feedback signals. I'd recommend using Startdrive commissioning software from Siemens for setting up the motor parameters, it's made the process quite straightforward for me. Moreover, when it comes to resolver configuration, it would be ideal to use the resolver evaluation board to convert the resolver signals into a format that the Siemens S120 drive can understand. However, keep in mind that one of the challenges you might face is the tuning of control loops because Lenze motors have slightly different electrical characteristics compared to Siemens motors. Hope this helps, and feel free to ask if you have any other questions.

In my experience, integrating Lenze servomotors with Siemens S120 drives is possible, though it requires meticulous configuration of the resolver and servo parameters. The key is to ensure that the resolver's signal is correctly read by the Siemens drives. Pay attention to the RDW (resolver data word) setting, which you should adjust based on your Lenze resolver specifications. You should also modify the motor speed and torque settings as per your application requirements to prevent against any unforeseen complications. Another critical area is reviewing your cabling - follow Siemens' installation guide and check any signal conversions. Would strongly advise testing in a controlled environment before going live with any application. Remember, safety always comes first.
