Hello friends, I am currently facing a challenging situation with a project deadline approaching rapidly, leaving me in urgent need of assistance. Originally, the project called for the use of AB Powerflex 4M, a system I am quite familiar with. However, in an effort to reduce costs, our boss has instructed us to utilize LENZE 8200 vector drives, a technology that I am unfamiliar with and unsure how to commission. This project involves a simple application that requires a stop/start command, speed control via a potentiometer, and fault notification through the use of auxiliary contacts. I am struggling with the wiring at the drive terminals and programming processes. I am certain that there are forum members out there who have experience with LENZE 8200 vector drives and can provide valuable insights. I have been going through the system manual for the Lenze EDS82EV903, but I am still struggling to comprehend it fully. For further reference, the LENZE 8200 vector drive details are as follows: Type: E82EV751 Input: 230V 1~ Output: 230V 3~ Power: 0.75 Kw/1Hp Thank you.
Our plant is equipped with a shared drive system. I utilized the Lecom A/B communication module to configure the settings using Lenze's global drive control software. I had to replace the module as the original one was faulty, requiring me to upload and download the parameters. Using the software made it significantly easier to locate specific parameters. I will share our parameter settings for reference and to assist you in troubleshooting further.
Setting up a Lenze drive control connection is straightforward and requires no modifications to default settings. If you are using a 4-20mA control signal from a PLC, you may need to make adjustments for a potentiometer input.
While reviewing my notes, I came across the following information:
BryanG drawings are accurate and suitable for factory settings. E4 represents CW/CCW rotation, E3 is for DC injection brake, and E2 and E1 are used for selecting fixed speed setpoints. X1.2/K11 Relay output features a normally-closed contact that opens to indicate a TRIP, while X1.2/K12 Relay has a mid-position contact. X1.2/K14 Relay output includes a normally-open contact that closes in case of a TRIP. For detailed instructions on setting up the system, refer to the system manual available at http://src.lenze.com/lenze-bibliothek/en/A1%20-%20Frequency%20inverter/A10%20-%208200%20vector/SHB_8200vector_0,25-90kW_SW3-X_v3-0_EN.pdf. Chapter 8 of the manual provides a step-by-step guide for commissioning the drive.
Hey Bryan, can you tell me which terminal number the -black goes to? It's located right across from terminal 28. Thanks!
Hello! I've had experience with Lenze 8200 Vector drives, so maybe I can help a bit. It indeed requires a slightly different approach compared to the AB Powerflex 4M. The basic wiring for your application isn't too complicated. For start/stop command, you could use terminals 33 (Start) and 34 (Stop), assuming the drive is in Terminals mode. The speed control should go to terminal 53 (AIN1), and fault notification could make use of terminal 13 (Output relay). You may have to set appropriate parameters both in 'I/O Setting' and 'Error Reaction' menus. Always ensure to power the drive down before tampering with the wiring, for safety reasons. Programming these drives can indeed be a challenge when you've not done it before. Primarily, you'll need to focus on P001 (operation mode selection), P006 (motor type), P020 (Motor rated voltage), P021 (Motor rated current), P022 (motor rated frequency), P027 (motor rated speed), and P033 (motor rated Power). These are the ones you have to set from your motor's nameplate. Once you've done these correctly, you should be good to go. Hope this helps a bit. Good luck!
Hi there, sounds like you're dealing with a pretty complex switch over. I have some experience with the LENZE 8200 vector drives. For a basic start/stop command and speed control, you'll want to wire your potentiometer to inputs X1.01 (0V) and X1.02 (+10V). Your start/stop commands can be assigned to the terminals X1.05 and X1.07. The error or fault notifications can be reflected at the relay outputs K1/K2 - the specific pin depending on the notification type. On the programming side, use the Lenze "Global drive control easy" (GDC easy) software to set your parameters and control the drive. The software is more user-friendly than manual programming. I recommend that you do a dry run with a motor, if possible, before implementing it into your project. Lastly, don't hesitate to reach out to LENZE support line - they've been really helpful whenever I had queries. Good luck with your project!
Hey there! I totally get how stressful it can be when you're suddenly facing a new system under a tight deadline. The LENZE 8200 series can definitely throw you a curveball if you're used to AB Powerflex. For your application, I'd recommend starting with the basic wiring—make sure the power connections are solid, then focus on the input terminals for the start/stop commands and the potentiometer for speed control. The manual is dense, but the sections on wiring diagrams and parameter settings are key. It might also help to check out online tutorials or even reach out to LENZE’s customer support—they can be super helpful. Good luck, you’ve got this!
Hey! I can definitely relate to the pressure of switching technologies under a tight deadline. For your LENZE 8200 drive, I'd suggest starting with the basic wiring diagrams in the manual—focus on the terminals for the start/stop commands and speed control first. Make sure to check the auxiliary contacts for fault notifications too; they usually have clear input/output assignments in the documentation. If you can, look for any online tutorials or videos specific to the E82 series—it might clarify some of the programming nuances for you. Finally, don't hesitate to reach out to LENZE support or your local distributor; they can be a great resource when you're in a crunch. Good luck, and hang in there!
Hey there! I totally get how tricky it can be to switch gears on a project like this, especially under time pressure. For wiring the LENZE 8200, a good approach is to start with the basic terminal functions outlined in the manual—focus on connecting the stop/start commands and the potentiometer for speed control first. Make sure you're using the right parameters in the drive's programming software; it often has a user-friendly interface that can guide you through setting up those functions. It might also be helpful to check out some online videos or tutorials, as seeing the setup in action can make things clearer. Don't hesitate to reach out here with specific questions about the wiring or settings as you go; we're all here to help! Good luck!
