Posi- and synchronous operating
PS.40 "reference point window" = 300 increments
The initiator signal is evaluated only if the direction of rotation is counter clockwise and the actual position lies
within a range of700...1300 increments. With this, the reference marker 2 is masked for the return path.
The following figure illustrates the connection between direction of rotation, target, the values
of PS.46 / 47 and
the reference point window PS.40.

Index A:
PS.24 = 4000
PS.46 = 500
PS.47 = 500 Index B:
PS.24 = 6000
PS.46 = 650
PS.47 = 800
The parameter PS.45 "adjustment index selection" is identical to parameter PS.23 "index/selection". It has
been inserted here a second time only to simplify the operation.
7.12.4.14 Posi mode / start positioning
A "start positioning" command can be generated by various means:
●
via digital input
The digital input is selected via parameter PS.29 "start positioning input selection". Alternatively, the
function "start positioning" can be associated with an input in the parameters di.11...di.22 (see chapter
7.3 Digital inputs)
●
by means of the control word SY.50 or SY.43
To start the positioning by means of the control word Sy.43 ("control word long") and Sy.50 ("control
word low"), respectively, bit 10 "start positioning" must be switched from 0 to 1.
Sy.43: Control word long
Sy.50: Control word low

0 Without function for positioning
1024 Switch from not activated to activated starts positioning
Starting a new positioning is only possible if bit 10 has temporarily been set to 0.
