1 OVERVIEW
1.1
SYSTEM CONFIGURATION
I/O Unit-A is connected to a CNC and cell controller through a high-speed serial interface, I/O Link i or I/O
Link.
(*1) Operator’s panel connection unit
(1) The I/O Link i or I/O Link consists of a master and slaves.
Master: Series0-C, Series15/16/18/20/21, Series15i/16i/18i/20i/21i/30i/31i/32i/35i/0i, Power
Mate-D/H, Power Mate i-D/H, F-D Mate
Slave: I/O Unit-A, I/O Unit-B, Power Mate, operator's panel connection unit, and Series 0-C, and so
on
(2) One I/O Link can connect to up 16 groups of slaves. If the master is not a CNC, one slave group can
contain up to 2 of I/O Unit A (2 base units). If the master is the F-D Mate, however, one group can
contain up to 4 I/O Units.
(3) One I/O Link i can connect to up to 24 slave groups.
Only one I/O Unit-A (one base) can connect to one group.
(4) I/O Link i allows no base expansion.

d A The fuse in the interface module has blown.
⇒ Eliminate the cause that made the fuse to blow, then replace the fuse with a spare. (See
Chapter 3.) The following may cause the fuse to blow:
• A sum of power requirements for all input modules exceeds the rating. (Refer to Section 4.4
in Part I.)
• A voltage of +24 VDC, supplied from input module AID32A1, AID32B1 or AID32H1 to
the outside, is short-circuited to the cabinet or the like.
• The interface module or any of the I/O modules is defective.

c
If PWR is off, go to item 1).
d
The attempted power turn-on sequence was incorrect.
⇒ The slaves (I/O Unit-A, Power Mate, Series 0, etc.) must be supplied with power at the same
time or before the master (CNC or F-D Mate) is supplied with power. (Refer to Section 4.2
in Part I.)
If an attempt is made to supply power to a slave on an interface module after the master is
turned on, LINK on the interface module is not turned on provided that the interface module
corresponds to that slave or to any slave ahead of that slave (one on the far side with respect
to the master).
e
I/O Link cables are broken or short-circuited.
⇒ With reference to Note below, check the cables, and take an appropriate action.
f
Any device on the I/O Link is defective.
⇒ With reference to Note below, find a defective device, and take an appropriate action. If an
I/O Unit seems to be defective, replace interface module with a spare.
NOTE
How to pinpoint a failure in the I/O Link in event of items d to f .
Check the LEDs on the master to find out which group contains slaves whose I/O
Link is established with the master. (Refer to the maintenance manual for the
master.)
For example, if the master is linked to slaves (slave #0 and #1) that belong to separate
groups, the timing of turning on slave #2 is bad, the cable is broken or short-circuited at
point (a), slave #2 is defective.
If the master is not linked to any slave, the master may be defective.
NOTE
Some i series CNC models check the number of I/O Link slaves. If there is a group
that is not recognized, I/O Link is not established with all groups.
Recognized groups can be checked on the PMC diagnosis screen of each CNC.
(3) LINK is turned on once, then off.
c
One of the devices on the I/O Link is turned off.
⇒ Turn off all devices, then turn them on.

f
Any device on the I/O Link is defective.
⇒ With reference to the maintenance manual for the master, find a defective device, and take
