No support. The document provided with the controllers states that they will work until approval (48 hours after signing the contract), but many days later and nothing. no contact. The controllers seem to work. The values used to set the motor in motion are very different from other controllers. The heat worries me the most. The heat generated by the controllers is very bad and I'm worried about my project as it's a bit closed and the heatsink is so hot you can't touch it. Spend a little more and get a MOSFET-based controller.
