11.4.3.5 Retracting of an activated limit switch
By setting MAN_bReleaseLimitSwitch to TRUE, retracting from an operated limit switch is possible.
The traversing process in the corresponding retracting direction is carried out until the limit switch
is no longer activated.
• 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 after the
limit switch has been abandoned until MAN_bJogPositive or MAN_bJogNegative are reset to
FALSE.
• If the direction opposite to the retracting direction is preselected instead, the drive stops, and a
corresponding status is shown via the status output MAN_dnState.

Tip!
An activated limit switch can also be exited again by manual jog in the retracting direction
via the control input MAN_bJogPositive or MAN_bJogNegative.

Note!
Retracting from a limit switch is only possible if it is still activated, i. e. if the
corresponding limit switch input of the limiter is still activated. Therefore ensure that if
a limit switch is approached, its trigger mechanics is not "overtravelled", for instance by
a too great mass or drive, so that by this the limit switch is no longer activated.
