3. Only for linear axes:
– p2503 = 1,000,000
– p2506 = leadscrew pitch in µm (SINUMERIK: MD 31030 * 1000)
4. p0010 = 0
5. Backup the drive data by copying from RAM to ROM.
Note
If it is necessary to reverse the measurement direction for the direct measuring system, then
both the speed and position must be reversed together (p0410[1].1 = p0410[1].0 = 1) so that
p0410[1] = 3H.
If the measuring direction for the direct measuring system matches the measuring direction of
the motor measuring system, then p410[1] must be parameterized = 0H.
Licensing
The license for SINAMICS standalone is an axis license. Detailed information about licensing
is provided in Chapter "Licensing (Page 776)".
The license for SINAMICS with SINUMERIK is a machine license within SINUMERIK. The
license can be activated in SINUMERIK Operate in the menu "Commissioning > Licenses".
Activation means that the NC must be switched on (power on).
Preassigning parameters
We recommend the following parameter preassignments:
Parameter Default value
p3702 APC load speed/motor speed
weighting
p3778 APC speed limit
p3779 APC speed limit monitoring
time
p3701 Selecting the direct measur‐
ing system
Drive functions

9.14 Advanced Position Control (including Active Vibration Suppression)
signifies that the internal resolution is 1 LU = 1 µm.
Explanation
The value is preassigned to "1" to allow compatibility with older firmware
versions. Set a starting value of "0" to optimize the encoder combination.
Setting the limit for the APC output value. For standard Siemens motors
(1FT, 1FK) with rated speeds in the range 2000 to 6000 rpm, we recom‐
mend that a speed limit of 500 rpm is set. Set the speed limit so that the
required manipulated variable of the APC controller is reached.
Monitoring time for speed limiting. A suitable value is 50 ms.
Measuring systems integrated in the drive: If a direct measuring system is
used, then this must be selected for the APC. In the default setting, the 2nd
measuring system of the drive (p3701 = [2] encoder 2) is used. If a 3rd
measuring system (p3701 = [3] encoder 3) is available, then this can also
be used.
Measuring systems not integrated in the drive: Direct measuring systems
from signal sources that do not belong to the drive can also be used. To do
this, BICO sink (p3749) is connected, and the signal scaling is set using
p3748. Activation is realized with p3700.9 = 1, where p3701 is ignored.
The use of this technique is relevant for master-slave axes (see also the
example in Chapter "APC with load velocity control (Page 576)").
