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" or the "Drive" from "SINAMICS_Integrated" in the Project Navigator, and then
open the "Expert List" by selecting the "Expert" command from the shortcut menu.
If p0115 sampling times are required which cannot be set using p0112 > 1, then you can directly
set the sampling times using p0115. To do so, p0112 must be set to "0" (Expert).
If p0115 is changed online, the values of higher indices will be adapted automatically.
Note
At
the SINAMICS end, there are further rules for setting the sampling times. You will find these
described in the
SINAMICS S120
Function Manual, Section Rules for setting the sampling
time.
Example
A default value of 4 ms is set for the SINAMICS Integrated setpoint channel p0115[3]. 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.
Incorrect cycle clock setting
If the SINAMICS cycle clocks are not set correctly, this can be seen by the following messages:
● A01223 CU: Sampling time inconsistent and/or
● A01902 PB/PN isochronous operation parameterization impermissible and/or
● F01043 seruizs error downloading project
In this case, check the cycle clock settings on all drive objects signaling this error.
Note
An overview of errors reported by the SINAMICS Integrated is provided in the
SINAMICS S
List Manual.
