2-3-2 Standard Wiring Method
The number of man hours required for wiring will be reduced and the reliability of the Unit
will be improved if OMRON Cables are used.
Give sufficient consideration to noise countermeasures when wiring
H Using Connection Cables
Use the following Cables to connect the Unit to peripheral devices. Always use OMRON Cables when
connecting the Resolver, in particular, to ensure reliability of the Unit.
