    TB6600HG Stepper Driver Alert LED Lit Up, Motor Not Working?

    Hi all, I have a cheap stepper driver that I can't find elsewhere aside from the eBay auction that I bought it from so I can't find any documentation. It was working fine previously, but I went to begin a cut and it didn't move the motor, and the "warning" LED lit up, which is connected to the "ALERT" pin of the TB6600HG chip. The datasheet for the TB6600HG says it is the "TSD/ISD Monitor Pin", (I guess it could mean thermal shutdown and current shutdown, but i'm unsure), but I am not very good with electronics, and don't know what caused this or how to fix it, can anyone help?

    Josh

    If you connected or disconnected the motors with the power on, you probably fried the chip. The chip cost more than the driver, so it is not worth fixing. Buy another.
