8.2.1.4Infinitemotiontaskwhenusingindexingtablefunction
In the case of infinite motion tasks the drive moves at constant speed, regardless of a
transmitted target position, until the mode is deactivated or is overwritten by a new
motion task. On switching to the next driving set (absolute or relative), the new target
position is approached in the current direction of movement. A preset path
optimization is ignored when the indexing table is active.
8.2.1.5Relativemotiontaskwhenusingindexingtablefunction
Relative driving jobs may relate to the current target position or to the actual position.
For more information see "Field Buses" user manuals.
In the case of relative driving jobs greater travel distances than the circumferential
length are possible.
Example without gear ratio:
l Circumferentiallength=360°
l Relativetargetposition=800°
l Startposition=0°

8.2.2Sercos
When using the Sercos profile, scaling of the units is termed weighting. The
weighting describes the physical unit and the exponent with which the numerical
values of the parameters exchanged between the master control system and the
drives are to be interpreted. The method of weighting is defined by the parameters
for position, speed, force/ torque and acceleration weighting.
