6.15.3 Retracting from hardware limit switches
)
Note!
Retracting from a hardware limit switch is only possible if the limit switch is
still activated.
Ensure by the trigger mechanics that an approached hardware limit switch
remains activated as long as the drive is outside the permissible travel range.
The two hardware limit switches must not be activated at the same time.
Otherwise it is not possible to detect the traversing direction for retracting.
By setting the control bit Ctrl1.RelLimSwitch = 1, retracting from an active hardware limit
switch is possible by travelling in the corresponding retracting direction until the limit
switch is not active anymore.
ƒ Positive hardware limit switch approached:
– Retracting in negative direction until the positive limit switch is not active
anymore.
ƒ Negative hardware limit switch approached:
– Retracting in positive direction until the negative limit switch is not active
anymore.
