L

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.

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:

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 ... 100) 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 ... 100) 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.
