6.5 Additional information on configuring the SINAMICS Integrated
6.5.1 Settings for DP slave properties
Settings in HW Config
Depending on the cycle clock ratios (bus cycle clock, servo cycle clock) and the drives used,
it may be necessary to change the properties of the DP slave (SINAMICS Integrated) on the
PROFIBUS Integrated.
Open HW Config. Double-click the SINAMICS Integrated to display and, if necessary,
change the properties of the DP slave on the "Isochronous mode" tab. Example:
● Synchronizing a drive to the isochronous DP cycle
SINAMICS Integrated and CX32-2 can only be operated isochronously. For this reason,
this option cannot be deactivated.
● Changing the master application cycle (T
MAPC
)
The master application cycle must always be the same as the servo cycle clock set
(setting: "Context menu of the D4x5-2" > "Set system cycle clocks" in the project tree).
Provided that the DP cycle is not scaled down to the position control cycle clock, the
master application cycle will always be the same as the DP cycle.
Note
As of V4.3, a reduction ratio for the DP cycle to the Servo cycle clock is possible. The
reduction ratio is only permitted when PROFINET IO with IRT has not been configured.
● Changing the DP cycle (T
DP
)
Depending on the requirements in terms of the quantity structures and the response
times, the DP cycle may need to be changed (see also
SIMOTION SCOUT Basic
Functions
Function Manual).
In addition, the minimum DP cycle for vector drives also depends on the speed controller
clock cycle, which in turn depends on the drive quantity structure and the device type
used. This means that, particularly in the case of vector drives, the DP cycle must be
checked and changed if necessary (see Using vector drives (Page 211)).
Note
After T
DP
has been changed on the PROFIBUS master, the drive system must be
switched on (POWER ON).
● Changing the T
I
and T
O
times
A change to T
I
/T
O
is required in the case of vector drives, for example, where the T
I
/T
O
time depends on the number of vector drives or, with chassis devices, on the device type
used.
