there's a red light active on the inside the corner of my cw230 stepper driver, but there's nothing that says what it's for. is that bad? on the cw8060 driver there's two LED's and the red one says al

For the 3.0A driver (CW230), the red led means that it is functioning correctly. It is confusing that they are made this way, but if the red led is lit then everything is fine. As the 6.0A driver (CW8060) the green led means that it is functioning correctly, and the red led when there is a error.
