YASNAC PCNC Connecting Manual Chapter 9: Connection of I/O Module
9.2 I/O Module Connection Details
This section describes the connection details between the CNC unit and the I/O module.
9.2.1 Connection between Units
If FC810, FC815 or FC860 is used, +24V of standard power supply unit is output to CN7-1
and CN7-2 terminals. Use the twisted-pair shielded cable with characteristic impedance of
120
Ω
for the signal cable of /SIG AND SIG signals.
Note: Without the power supply having overcurrent protection or overcurrent protection
countermeasure for output signal (Section 10.3.2 “I/O Circuit of I/O Port”), a fuse
should be installed in the +24V line for I/O overcurrent protection. As the required
capacity of the fuse changes depending on the I/O points, refer to Section 10.3.3
“Power Supply for I/O Signal” for details (e.g. A 7.5 Amp fuse is required for 112
inputs and 96 outputs).
