It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM860T can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM860T an ideal choice for high requirement applications. Features Step & direction (PUL/DIR) control Input voltage 18-80VAC or 36-110VDC Pulse input frequency up to 200 KHz. 16 selectable microstep resolutions from 400 to 40000 8 selectable peak current including 2.40A, 3.08A, 3.77A, 4.45A, 5.14A, 5.83A, 6.52A, 7.20A Soft-start with no “jump” when powered on Specifications Mechanical Specfications DIP Switch Configurations Protection Functions Troubleshooting In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently. It is important to document each step in the troubleshooting process. You may need this documentation to refer back to at a later date, and these details will greatly assist our Technical Support staff in determining the problem should you need assistance. Review: Works with my Acorn CNC controller - Did a milling machine CNC conversion. Used 3 of these drives with NEMA 34 motors. Works good Review: Purchased to update older Cnc router..machine runs smooth and quieter - So i have been running my industrial cnc router for some time now, and thought i should update the drivers. Glad i did because these drivers are much smoother with motion control and quieter. Worth it for the price. Note used on 80v ac and nema 34’s. ## Features - Stepper motor driver DM860T is updated to version V3.0, but New and Old versions in desertcart's warehouse are shipped randomly. - Top-level Quality, Affordable Price, Professional Driver, Manufactured by Leadshine - Suit for Nema 34 and 42 Stepper Motor - 2.4~7.20A, 18-80VAC or 36-110VDC, 1/256 Microstep Resolution - Ideal solution for applications that require low-speed smoothness ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06Y68Q8ND | | Best Sellers Rank | #282,044 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #227 in Electrical Motor Controls | | Brand | STEPPERONLINE | | Brand Name | STEPPERONLINE | | Customer Reviews | 4.6 out of 5 stars 92 Reviews | | Item Weight | 580 Grams | | Manufacturer | Leadshine Technology Co., Ltd. | | Material | Copper | | Material Type | Copper | | Model | DM860T | | Model Name | nema | | Part Number | DM860T | | Speed | 6 RPM | | UPC | 715624558980 715624558805 | | Voltage | 110 Volts | ## Product Details - **Brand:** STEPPERONLINE - **Material:** Copper - **Model Name:** nema - **Speed:** 6 RPM - **Voltage:** 110 Volts ## Images ![STEPPERONLINE CNC Digital Stepper Motor Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 and 42 Motor DM860T - Image 1](https://m.media-amazon.com/images/I/61ArIMYd58L.jpg) ![STEPPERONLINE CNC Digital Stepper Motor Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 and 42 Motor DM860T - Image 2](https://m.media-amazon.com/images/I/61uN2IlKk4L.jpg) ![STEPPERONLINE CNC Digital Stepper Motor Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 and 42 Motor DM860T - Image 3](https://m.media-amazon.com/images/I/61c9L7n3sTL.jpg) ![STEPPERONLINE CNC Digital Stepper Motor Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 and 42 Motor DM860T - Image 4](https://m.media-amazon.com/images/I/51RZUvulCjL.jpg) ![STEPPERONLINE CNC Digital Stepper Motor Driver 2.4-7.2A 18-80VAC or 36-110VDC for Nema 34 and 42 Motor DM860T - Image 5](https://m.media-amazon.com/images/I/51Eluf2hqfL.jpg) ## Questions & Answers **Q: The driver says it can be wired ac or dc power, but the directions do not say how to connect dc (+) and (-) to the terminals labeled ac and ac. which one is the (+) terminal?** A: It's a good question. On the driver, it show two AC terminals, that meaning you can connect DC+ and DC- to these two AC terminals at random. Best regards Daniel Zhang **Q: I have 1 of these units currently throwing a fault code. Is it resettable or must it be replaced?** A: I have been through about a dozen of these. For me if cycling the power did not clear the fault I had to replace the drive. I know it has to be something simple so I have a box full of them that I "plan" to fix when I have time. **Q: can this this be used with nema 23 4.0 amp 1.8mh .9ohm ?** A: yes, of course. **Q: I see stepperonline also has power supplies. which one is best for this driver? i'd like to get one with a vent fan if possible. thank you.** A: We are pleasure to recommend you a suitable power supply, but we should know your stepper motor's size and the current.

Note used on 80v ac and nema 34’s. ### ⭐⭐⭐⭐⭐ The "Go-To" Drive for our Stepper-Based Controls *by S***R on April 25, 2019* We have used about three dozen of these drives without issue or failure. Amazon Prime is the best source for these drives (price, stock, and speed to get). Our small company builds retrofit controls and rebuilds CNC machinery. We have successfully used these drives on NEMA 23, 34, and 42 motors. For us this drive was a game changer because of the power supply requirements. Nearly every older CNC machine that we come across has a large stepdown transformer in it. Instead of scrapping these transformers and buying or building a custom power supply we simply reuse the old machine transformer to provide 60VAC input. In the few cases where we did not have a spare old transformer we used a 2000 watt power converter (also purchased from Amazon) to step down 120V line voltage to 60VAC.
