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.
