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
可作为使能信号输入口或通用输入口。
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.
