(2) Dedicated wiring STO function
[1] System configuration
This method is used to shut off the motor power with STO function only for the specific axis.
For example, to shut off the motor power with STO function only for the magazine rack axis, install a safety
door for tool change and directly connect the door open/close signal to the STO signal input (CN8) of the drive
unit. Warning A4(sub-number 0001) is detected while STO function is shutting off the motor power.
(Note) Always insert the provided short-circuit connector to CN8 for other than magazine rack axis and
cause short circuit in the STO signal.
