Terminal 37 is used for Safe Stop. For instructions on Safe Stop installation, please refer to the section
Safe Stop Installation
of the Design
Guide.
* Terminal 37 is not included in AutomationDrive FC 301 (Except AutomationDrive FC 301 A1, which includes Safe Stop).
Relay 2 and Terminal 29, have no function in AutomationDrive FC 301.
In rare cases, very long control cables and analog signals may, depending on installation, result in 50/60 Hz ground loops due to noise from line power
supply cables.
If this occurs, it may be necessary to break the shield or insert a 100 nF capacitor between shield and chassis.
