S-ramp time
When the S-ramp time is selected for a profile, it is executed with S-shaped ramps, e.g. acceleration and
deceleration processes are started smoothly to reduce the jerk and thus prevent the drive components
from damage.
• The acceleration/deceleration specified in the profile are only reached after the defined S-ramp time
has elapsed.
• This type of acceleration/deceleration is required for e.g. sensitive machine parts with clearance.
• The slower acceleration increase with the S profile prolongs the positioning time compared to the
time optimal L profile.
n without jerk limitation (L profile)
o with jerk limitation (S profile)
Final speed
Selection of the speed by which the drive is to start the next profile after reaching the target position.
"Velocity changeover" or "Overchange" can be implemented with a final speed that is non-zero, i.e.
when the target position is reached, a second positioning process is started immediately without the
drive being decelerated to standstill at the first target position:
n Target position
o Final speed (here unequal "0")
Start of TP window / End of TP window
These profile parameters serve to restrict the range for a touch probe positioning (residual path
positioning) in which touch probes are to be detected.
Sequence profile with TP
Profile data set (profile no. 1 ... 75) in which the profile data of the profile are stored which is to be
executed after a touch probe has been detected.
• For the setting "0" no further profile connection by touch probe is effected.
Sequence profile without TP
Profile data set (profile no. 1 ... 75) in which the profile data of the profile is stored which is to be
executed after the standard profile has been executed (profile chaining).
• With the setting "0" no profile chaining is carried out.
• The sequence profile defined in this profile parameter is executed even if no touch probe has been
detected within the defined TP window.
