3.1.2 X5, X6, X7 and X8 Digital Inputs
X5 ~ X8: Optically isolated, differential, 5-24VDC; Minimum pulse width = 100μs, 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
Since the input is an optically isolated circuit, a 5-24V power supply is needed.
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 StepSERVO Quick Tuner
software to configure the function of X5, X6, X7 and X8.
The diagram below show how to connect the X5, X6, X7 and X8 to various commonly used devices.
