The following chapters are all based on the "New Set Value" method. The "Start Position-

4.8.2.2 Positioning Data

The controller has 16 positioning records (1..16) and one active positioning set (0).
The Current Positioning Set Number parameter
which the data will be taken at the next start command (rising edge of "New Set Value"
control bit, control word Bit 4). The data will be copied from the specified positioning set
into Positioning Set 0.
It is also possible to set a mode (see also Z118.2–, Bit 10) in which the positioning data
are transferred and the positioning is started when the current positioning set
changed. In this case the edge of the "New Set Value" control bit is not required, however
the bit must be set.
There are two different positioning procedures:
m Set specification ("Single set value"): Procedure using individual positioning records: 
m Set Value specification ("set of set values"): Procedure using a speed profile.
The state of the "Change Set Immediately" bit in the control word is evaluated in conjunc-
tion with the activation of a motion task, i.e., always on the rising edge of "New Set Value".

Bit 4 "New Set Value" in the drive manager control word is used here. The positioning
set data are copied on each rising edge of this bit (Set X to Set 0), adopted internally
and the positioning procedure started.
The start of positioning takes place with Bit 11 "Start Positioning" of the drive manager
control word.
on page 562).
With this procedure, a positioning set is started and the drive positions at the target and
holds there. It is possible to activate a new task, even during positioning (edge of New
Set Value). This is then taken up immediately; the drive thus changes directly to the
new positioning data.
The selection of Set Specification depends on the setting in
n Bit 11 = 0: Interpretation of Bit 5 is compatible with b maXX 4400. Set Specification
is selected when Bit 5 is cleared.
n Bit 11 = 1: Interpretation of Bit 5 in accordance with IEC61800-7-201. Set Specifica-
tion is selected when Bit 5 is set.
With this procedure, several positioning data are activated in sequence. The drive is
not intended to remain at the first target, but rather to activate the next data from the
first target position. 
The selection of Set Value Specification depends on the setting in
Bit 11.
n Bit 11 = 0: Interpretation of Bit 5 is compatible with b maXX 4400. Set Value Speci-
fication is selected when Bit 5 is set.
n Bit 11 = 1: Interpretation of Bit 5 in accordance with IEC61800-7-201. Set Value
Specification is selected when Bit 5 is cleared.
