Operation
■For FX5-SF-MU4T5
Connect I0/I1 and I2/I3 of an FX5-SF-MU4T5 using OR logic.
■For FX5-SF-MU4T5 and FX5-SF-8DI4
Connect the inputs of an FX5-SF-MU4T5 and the inputs of the OR function
*1
of an FX5-SF-8DI4 using OR logic.
*1 When the INPUT A rotary switch of an FX5-SF-8DI4 is set to '7', I0/I1 and I2/I3 will be the input of the OR function. When the INPUT B
rotary switch of an FX5-SF-8DI4 is set to '7', I4/I5 and I6/I7 will be the input of the OR function.
• The output of the FX5-SF-MU4T5 is kept ON while the OR function is enabled and any of the safety inputs are turned ON.
• During the OR function is active, make sure that there is no danger to people or parts of the machine by using other
protective equipments. For example, when using the OR function for a setup mode, make sure that the protective
equipments, such as a safety setup mode of a machine, are forcibly enabled.
