• When using MECHATROLINK I/O Modules, use establishing MECHATROLINK communications as an
interlock condition.
Failure to observe this caution may result in damage to the product.
When using MP2000 series option output modules or option output units, if the Machine
Controller main unit power supply is turned ON after an external power supply such as a 24-
V power supply for the I/O is turned ON, the output from the option output module or the
option output unit may be momentarily turned ON.
Before turning ON the Machine Controller main unit power supply, configure the circuit that
turns it ON.
