Emergency Stop and Enable Circuits: Example for Wiring Considering Safety Category 3
* Regarding the contact in connector area for teaching, there is a bypass relay connected, thus it
cannot be used as a safety circuit. (It can be applicable with a special order of “with no bypass”
when using a contact on the connector area for teaching. In such a case, use a dummy plug (DP-2)
when the connector for teaching is not to be in use.)
* Use a duplexing PC connection cable (CB-ST-A1MW050-EB) when teaching is conducted with PC
by using the connector for teaching.
* The power supply specifications between the terminals for MPO and MPI are as described below.
