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 5-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.
Recommended surge absorption diode: RU2 (Sanken Electric) or the
equivalent
