9.10.1.2 Hardware limit positions (limit switch)
The travel range limits are monitored via limit switch inputs LIM_bLimitSwitchPositive and
LIM_bLimitSwitchNegative of the SB LS_Limiter.
Both inputs react to the TRUE status and must be connected to the corresponding digital
inputs which are connected with the limit switches.
[9-6] Example: Connection of the travel range limit switches to the digital inputs 3 & 4
r If the limit switch is activated, the drive axis is stopped automatically and a changeover
via the function state "Drive is stopped" to the function state "Error" is effected.
r An error is caused via an internal system interface and entered in to the logbook of the
controller. The drive can only be traversed again when the error is acknowledged.
r An activated limit switch can be retracted using the function "Retracting the limit
switch".Retracting of an activated limit switch
(C 161)
r When the limit switches are connected to the distributed terminals, both inputs
LIM_bLimitSwitchPositive and LIM_bLimitSwitchNegative of the SB LS_Limiter
can be
connected via a bus system (e.g. system bus) with the distributed terminal.

inputs in C00114
