11.11.2.3 Hardware limit positions (limit switch)

Monitoring of the travel range limit by means of limit switches is effected via the inputs

LIM_bLimitSwitchPositive and LIM_bLimitSwitchNegative of the LS_Limiter SB.

• The two inputs respond to the TRUE state and are to be connected to the corresponding digital

inputs to which the limit switches are connected:

[11-28] Example: Connection of the travel range limit switches to the digital inputs DI3 & DI4

• If the limit switches are connected to decentralised terminals, the two inputs

LIM_bLimitSwitchPositive and LIM_bLimitSwitchNegative can be connected to the decentralised

terminal via a bus system (e. g. system bus).

• If one of the two monitoring inputs is set to TRUE:

• The error response "quick stop by trouble" is carried out, i.e. the drive is braked to standstill

within the deceleration time set for the quick stop function irrespective of the setpoint

selection.

• The fault message "Pos. SW limit switch has tripped" or "Neg. SW limit has tripped" is entered

in the logbook of the controller.

• A corresponding status is output via the LIM_dnState output.

• The drive can only be traversed again after the error has been acknowledged.

 Note!

If the digital inputs used for the connection of the limit switches are to be designed in a

fail-safe manner (activation at LOW level), you simply change the terminal polarity of

the corresponding digital inputs in C00114

.

 Stop!

If a limit switch is approached by means of the basic function Position follower and by

this a fault with the "Quick stop by trouble" response is activated, always a set/actual

adjustment of the position has to be carried out before the fault is acknowledged

, as

otherwise an uncontrolled motor movement may result after the fault is acknowledged!
