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-clicking the SINAMICS Integrated enables you to display and, if
required, 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:
"Shortcut menu of the D4x5‑2" > "Set system cycle clocks" in the project tree). Provided
that the DP cycle is not reduced to the servo 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 response times, the
DP cycle may need to be changed (see also
SIMOTION Runtime Basic Functions Function
Manual).
In addition, the minimum DP cycle for vector drives also depends on the speed controller
cycle clock, 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 Section Use of vector drives (Page 227)).
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.
If you change the settings for the SINAMICS Integrated, you must also change the settings on
the CX32‑2 modules accordingly. This is easily done by using the Align button to transfer the
settings for all the CX32‑2 modules.
