I just received a new VESC from Ollinboard. I adjusted the settings using a current limiting power supply at 12V and 10A. After successfully running the auto detection, and adjusting the voltage cutoff settings, I tested it with full 12s voltage. The motor would spin up with no load, but had no torque when a load was applied. The motor would just cog. Even when allowing the motor to reach a higher RPM before applying a load, the motor would cog. I tried increasing the startup boost to 0.1, but that didn’t help too much. I did a little more bench testing, trying different startup boost settings. The last time I tested it with the full 12s voltage, I saw smoke coming from the DRV chip. Any help with this issue is greatly appreciated. It’s pretty frustrating since I just received the VESC.
