The information (0…15) after the field name Positioning indicates that the selection " relative " applies
to all positions in the 0 to 15 position group. Some of the other parameters in this menu apply to all 64
positions. In this case the field name is followed by (0…63). If no information is given after the field
name, the parameter applies only to this position.
The Positioning field can be used to state whether the specified destination should be interpreted as
an absolute value (referring to the reference point) or as a relative value. Relative refers to the
current position setpoint, e.g. during a positioning run being performed. The option relative to last
destination calculates the new position on the basis of the destination reached or currently being
approached.
The relative option leads to different results depending on the setting in the field Start during
positioning (see below). If the combination relative / Wait for end of positioning run is selected, the
new position refers to the destination.
In the case of the combination relative/Interrupt actual positioning , the new destination will be
calculated starting from the current positioning setpoint.
The field Start during positioning defines the behaviour of the servo positioning controller when a
positioning run is still running and the controller receives a start command for a new destination. It has
the following options:

Wait for end of positioning run : The current positioning run will be completed before the new
positioning process is started. The next positioning run can be selected prior to the running
positioning run. The new positioning run will be started automatically when the current
positioning run is completed.

Interrupt actual positioning : The current positioning run will be interrupted and the new
position will be approached immediately.

Ignore start command : The positioning command for the new position cannot be selected or
started before the current positioning run is completed.
Please note that a bouncing switch at the digital start input may lead to problems if wait
for end of positioning run or interrupt actual positioning is allowed in the case of a
relative positioning run. As a result, the drive may move just a little too far!
The Messages field can be used to parameterize trigger signals which can be issued via the field bus
or a digital output. These trigger signals indicate the remaining distance up to the end of a positioning
run. The parameterized remaining distance applies to all 64 destinations.
Information on how to feed this message to the digital outputs can be found in chapter 5.5 Digital
outputs DOUT0 to DOUT3 .
The Start delay field can be used to define a certain delay period. After a start command, the servo
positioning controller has to wait until this delay is over before it can start the positioning run.
