Retracting of an operated limit switch

If control bit 7 (ReleaseLimitSwitch) in the
operated limit switch is possible. Traversing is carried out in the corresponding retracting
direction until the limit switch is not longer operated.
 If a direction preselection is made for retracting by means of control bit 4/5
(ManJogPos/ManJogNeg) in the retracting direction, travelling is continued, even after
the limit switch has been left, until the corresponding control bit is reset.
 If, instead, a direction preselection is made against the retracting direction, the drive
remains at a standstill.

Note!
Retracting from a limit switch is only possible if this switch is still in the operated
state, i.e. the corresponding limit switch input is still active. You must therefore
make sure that, when travelling to a limit switch, its tripping mechanism is not
"driven over" due to e.g. an excessively high mass or too much momentum so
that the limit switch is no longer in the operated state as a result.

Tip!
A limit switch that is in the operated state can also be moved away from again
through manual jogging in the retracting direction by means of control bits 4/5
(ManJogPos/ManJogNeg).
