3.1.2 X5, X6, X7 and X8 Digital Inputs
X5, X6, X7 and X8: optically isolated, single-ended, 5-24VDC for high level voltage, minimum
pulse width 100μs, maximum pulse frequency 5KHz
• X5 can be used as motor enable input or general purpose input.
• X6 can be used as alarm reset input or general purpose input.
• X7 can be used as general purpose input or touch Probe 1 trigger input.
• X8 can be used as general purpose input or touch Probe 2 trigger input.
Because the input is an optically isolated circuit, a 5-24V power supply is needed. For example,
you can use the power supply of the PLC when you are using a PLC control system, but if you
want to connect a relay or mechanical switch to the input , you must need a power supply.
XCOM is an electronics term for a single-ended signal connection to a common voltage. If you are
using a sourcing (PNP) input signals, you need to connect XCOM to the ground (power supply
-), if you are using a sinking(NPN) input signals ,the XCOM need to be connected to the power
supply +.
Use STF Congurator software for X5, X6, X7 and X8 function conguration.
