RW
Defines the analog input 1 source mode for current or voltage, also need to set DIP switches on control
board SW1.
0 = 0-20mA - current loop with an external supply the ground jumper is not required.
1 = 0-10V - If using the 10V supply on Terminal 1 of the drive, it will require a ground jumper from Terminal 6
to the AI- input terminal 3.
