Operation with long cams:
In this instance, there is no restriction, which means that the function is initialized across the whole trajectory.
Stop at distance calculated after deceleration limit switch
This function can be used to control the stopping of the moving part automatically once a preset distance has
been traveled after the slowdown limit switch.
On the basis of the rated linear speed and the speed estimated by the drive when the slowdown limit switch
is tripped, the drive will induce the stop at the configured distance.
This function is useful in applications where one manual-reset overtravel limit switch is common to both
directions. It will then only respond to help management if the distance is exceeded. The stop limit switch
retains priority in respect of the function.
The [Deceleration type] (dSF) parameter can be configured to obtain either of the functions described
below:
Note:
• If the deceleration ramp is modified while stopping at a distance is in progress, this distance will not be
observed.
• If the direction is modified while stopping at a distance is in progress, this distance will not be observed.

WARNING
LOSS OF CONTROL
• Check that the parameters configured are consistent (in particular, you should check that the required
distance is possible).
• This function does not replace the stop limit switch, which remains necessary for safety reasons.
Failure to follow these instructions will result in death, serious injury, or equipment damage.
