Baldor's VS1SP and VS1GV Drives
VS1SP and VS1GV drives have a PLC mode that allows 30 rungs of simple ladder logic to be embedded in the drive. Each rung consists of two input conditions that can be logically combined (AND, OR, XOR, NOR, NAND) to create an output condition. The input conditions can be the digital inputs of the drive or status bits in the drive itself. The outputs can be digital outputs or drive commands.
