Sequence I/O Signals

This section explains sequence I/O signals.
In this section, the word "open" or "close" shown in parentheses in parameter descriptions indicates that
the contact is open or closed.

5.3.1 Servo ON Signal (/S-ON)

This sets the servo ON signal (/S-ON) that determines whether the servomotor power is ON or OFF.

5.3.2 Overtravel

The overtravel limit function forces movable machine parts to stop by turning ON a limit switch if they exceed
the allowable range of motion.
For rotating applications such as rotary tables and conveyors, an overtravel function is not always necessary,
and in this case no wiring for overtravel input signals is required.
