VelocitySegment:
The VelocitySegment is used for a movement with constant
velocity, independent from the velocity of the guide value.
It is similar to a P1 TimePoly of type relative, but velocity
controlled instead of position controlled.

Value Description
range/
allowed
values
Float Velocity of the axis
during this segment.
The velocity must be
given in rps.
To ensure smooth
movements, the
velocities of all
segments that are
connected in the same
node should be the
same. If this is not
parameterized correctly,
a jump in velocity may
occur.

Representation
Coefficient representation: This representation is not
available.
SyncSegment:
The SyncSegment is used for a synchronized, velocity
controlled movement in relation to the velocity of the
guide value. It is similar to a VelocitySegment, but with a
coupling factor for the velocity (velocityRatio).
Illustration 2.98 Start/Endpoint Representation
Description
Acceleration of the axis
when increasing the
velocity. The
acceleration must be
given in rps per
second.
It is possible to
parameterize jumps in
acceleration when 2
succeeding segments
have different startAcc
and endAcc values.
Deceleration of the axis
when decreasing the
velocity. The
deceleration must be
given in rps per
second.
It is possible to
parameterize jumps in
acceleration when 2
succeeding segments
have different startAcc
and endAcc values.
Configures the
maximum torque used
during this segment.
The value is given per
mNm.
