 Incorrect signal wiring can cause damage to Units and the Servo Drive.
 Leave unused signal lines open and do not wire them.
 Use mode 2 for origin search.
 Use the 24-VDC power supply for the command pulse inputs as a
dedicated power supply.
 Do not share the power supply for brakes (24 VDC) with the 24-VDC power
supply for controls.
