B and L look like an output from the drive and an input to the controller, but the description makes it sound like contacts that enable the drive. I would recommend taking an open circuit voltage reading between B and L and putting a relay coil rated for that voltage. It could be an output that shorting could damage. Other than that I think you have it pretty much figured out.
