9.4.2.3 Retracting of an activated limit switch
By setting MAN_bReleaseLimitSwitch to TRUE a retraction from an activated limit switch is
possible. Travel in the retracting direction until the limit switch is not active anymore.
r If, while retracting, a direction is selected additionally via the control inputs
MAN_bJogPositive or MAN_bJogNegative towards the retracting direction, the travel is
continued even the limit switch has been abandoned until MAN_bJogPositive or
MAN_bJogNegative are reset to FALSE.
r If the direction is selected against the retracting direction, the drive stops and a
corresponding status is output via the status output MAN_dnState of the system block
LS_ManualJog .
O
Tip!
An activated limit switch can also be abandoned by manual jog in retracting
direction via the control inputs MAN_bJogPositive or MAN_bJogNegative.

Note!
It can only be retracted from a limit switch if this is still activated, i.e. the
corresponding limit switch input of the limiter is still active. Therefore ensure
that while travelling towards a limit switch that the trigger mechanics will not
be overtravelled by a too high mass or swing so that the limit switch will not be
activated by this.
