Rules for SIMOTION D410 DP
The general rule for SIMOTION D410 specifies that the DP cycle (D410 DP) forms the basic
clock of the cycle system. All cycles longer than this basic clock must be an integer multiple
of the basic clock.
This rule also applies to SINAMICS cycles, if one of the successive cycles is longer than the
basic clock:
●
Speed controller p0115[1]
●
Flux controller p0115[2]
●
Setpoint channel p0115[3]
●
Position controller p0115[4]
●
Positioning p0115[5]
●
Technology controller (p0115[6])
●
Onboard I/O p0799
●
Terminal module I/O p4099
The corresponding cycle must be an integer multiple of the basic clock (DP cycle).
If any change to the DP cycle violates this rule you must also change the SINAMICS cycle
clocks. In order to change the cycles in the Expert list of SIMOTION SCOUT, select the
"Control_Unit" from "SINAMICS_Integrated" in the Project Navigator, and then open the
"Expert List" by selecting the "Expert" command from the shortcut menu.
Example:
A default value of 4 ms is set at the SINAMICS setpoint channel. If the DP cycle is to be set
to 3 ms, the fact that an integer multiple value is required means that you will need to set
3 ms or 6 ms (for example) for the setpoint channel.
Current controller cycle clock
With the SIMOTION D410, the following current controller cycle clocks p0115[0] are
configured for the SINAMICS Integrated:
●
for servo: 125 μs or 250 μs
●
for vector: 375 μs (chassis) or 500 μs (PM340).

Operating the PROFIBUS interface (X21) as an MPI interface
The X21 interface can also be operated as an MPI interface instead of a PROFIBUS DP
interface. The typical (default) baud rate is 187.5 kBaud. A baud rate of up to 12 MBaud can
be set for communication with other CPUs. It should be noted, however, that a rate of
12 MBaud is not supported by all CPUs (e.g. smaller SIMATIC S7 CPUs).
