Precautions for Correct Use
Incorrect signal wiring can cause damage to units and the drive.
Leave unused signal lines open and do not wire them.
Use mode 2 for origin search.
Use the power supply for command pulse (24 VDC) as a dedicated power supply.
Do not share the power supply for brakes (24 VDC) with the 24-VDC power supply for controls.
The diode recommended for surge absorption is the RU 2 (Sanken Electric Co., Ltd.) or the
equivalent.
