MANUAL
B-63173EN/03-3
Item 6.9.9 Other Notes
Modified as follows
Before) DO signal reaction to a system alarm
If a system alarm occurs in the Power Mate using this 48/32-point I/O module,
or if I/O Link communication between the Power Mate and operator’s panel I/O
module fails, all the DO signals of the I/O module are turned off. Therefore,
sufficient care is necessary when setting up the machine sequence. Also, the
same phenomenon occurs if the power to the Power Mate or the I/O module is
turned off.
After) DO signal reaction to a system alarm
There is a possibility that the I/O module will not operate normally due to a failure of
CNC or I/O Link slave module, or abnormally power supply voltage. To prevent
accidents even in this case, design the machine to operate safely by making a safety
circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a
system alarm is occurred in the Power Mate which controls the I/O module, or if a
power of the Power Mate or the I/O module is turned off. However, it cannot be
guaranteed that DO signals of the I/O module will certainly be turned off. Therefore,
manage signals related to safety by making a safety circuit outside this I/O module.
Item 6.10.9 Digital Input/Output Module
Added the following description
DO signal reaction to a system alarm
There is a possibility that the Digital Output Module will not operate normally due to a
failure of CNC or I/O Link slave module, or abnormally power supply voltage. To
prevent accidents even in this case, design the machine to operate safely by making
a safety circuit outside the Digital Output Module.
The circuit of this Digital Output Module is designed so that all DO signals are turned
off if a system alarm is occurred in the Power Mate which controls the Digital Output
Module, or if a power of the Power Mate or the Digital Output Module is turned off.
However, it cannot be guaranteed that DO signals of the Digital Output Module will
certainly be turned off. Therefore, manage signals related to safety by making a
safety circuit outside this Digital Output Module.
