For PROFIBUS/PROFINET:
In the case of systems with a PROFIBUS DP connection, this MD corresponds to the
PROFIBUS DP cycle
time. This time is read from the configuration file (SDB-Type-2000)
during startup and written to the MD.
This MD can only be changed via the configuration file.
Note:
Reducing this MD can result in an automatic correction of
MD10064 $MN_POSCTRL_CYCLE_DESVAL_DELAY
that cannot be undone by a subsequent increase!
Details:
The basic cycle is incremented in multiples of units of the measured value sampling
cycle. When the system powers up, the entered value is automatically rounded to a
multiple of this incrementation.
Note:
Discrete timer division ratios can give rise to the entered value producing a value
that is not an integer after a Power OFF/ON.
For example:
Input =0.005s
after power OFF/ON =0.00499840
or
Input =0.006s
after power OFF/ON =0.0060032

Description: For SINAMICS-Integrated only:
Only relevant to operation with SINAMICS-Integrated drives on SOC modules.
Offset of the output of the setpoints via DMA in relation to the PROFIBUS DP cycle.
Modification of MD10064 POSCTRL_CYCLE_DESVAL_DELAY requires a warm restart of the NCK
and drive.
Offsets that exceed the set DP cycle are automatically corrected to a substitute value.
MD10062 $MN_POSCTRL_CYCLE_DESVAL_DELAY > 0: Default setpoint offset
MD10062 $MN_POSCTRL_CYCLE_DESVAL_DELAY = 0: Automatic determination of the setpoint
offset on the basis of the hardware transfer rates
The actually active offset value is displayed in MD10063
$MN_POSCTRL_CYCLE_DIAGNOSIS[4].
Note:
MD10064 $MN_POSCTRL_CYCLE_DESVAL_DELAY > 0 can reduce MD10050 $MN_SYSCLOCK_CYCLE_TIME
to the automatic correction of this MD, which cannot be undone by a subsequent
increase.
Recommendation:
In this case, set the original value or default value again.
