3.1.2 X5, X6, X7 and X8 digital Inputs
X5 ~ X8: Optically isolated, differential, 5-24VDC; Minimum pulse width = 100
μ
s, Maximum pulse
frequency = 5KHz;
X5 can be configured as servo on input or general purpose input
X6 can be configured as alarm reset signal input or general purpose input
X7 can be configured as Touch Probe 1 trigger input or general purpose input
X8 can be configured as Touch Probe 2 trigger input or general purpose 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. In the case
of SS series, 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 connect to the
power .
Please use
Step-Servo Quick Tuner
software to configure the function of X5, X6, X7 and X8
The diagrams below show how to connect the X5, X6, X7 and X8 to various commonly used devices.
