| − | The example below illustrates an alternative way of connecting limit switches that are connected in series. However this way requires that axis is being manually pulled away from end of travel if either switch is open as drive doesn't know which way is the safe running direction.

If such feature is desired, it's recommended to install second pair of limit switches or use soft travel limits that stop motion ''before'' the STO switches, so STO switches would serve only as backup.
