June 30, 20223 yr TSDZ2, 860C, 52V, OSF V20.1.3.....Just got a brake error after one year of no problems. This started after a recharge to 58.6 volts and the error occurs with or without the brake cables connected. I can access the menu, and all looks good and normal accept I don't get a Voltage reading on the display and the motor is locked. Trying new cables and upgrading OSF to V20.1C.4 did not help. Is there anyway of testing or bench checking the controller?
June 30, 20223 yr Is there anyway of testing or bench checking the controller? not without proven working LCD and cable.
July 3, 20223 yr Author not without proven working LCD and cable. I did try a replacement Display, with the correct firmware, and checked the cables for shorts/opens and I still get the brake error. Everything has been working flawlessly for the past year, until this problem.
July 3, 20223 yr Everything has been working flawlessly for the past year, until this problem. even after you unplug the brake sensors?
July 3, 20223 yr Author even after you unplug the brake sensors? Yes, I get the error even with both brake sensors unplugged.
July 3, 20223 yr Unplug the speed sensor to see if the brake error goes away. If it does not,then your controller is the source of the error.
July 3, 20223 yr Author Unplug the speed sensor to see if the brake error goes away. If it does not,then your controller is the source of the error. Thanks for your replies, I will give that a try.
July 18, 20223 yr Author Update, I finally made time to replace the controller, add thermal pads to the motor, update OSF V20 to .4 and now everything is back to normal. The controller was the culprit, but I not sure if my shutting off the battery first caused the "Brake Error" failure or just a defective controller. There were no visual burnt components on the controller.
July 18, 20223 yr Update, ............ There were no visual burnt components on the controller. I suspect that for what ever reason, the micro controller itself can become firmware corrupt or electronically fail and simply stops working. I have no proof that this is the case but my installation just stopped working after around 2,700km and shortly after I'd loaded v20.1c.2 for my vlcd6 setup - coincidence or not, I really couldn't say, but I could not communicate with the controller with my laptop, so that was it until I installed a new controller.
