Parameters With Follow-On Parameterization - Siemens SINAMICS G110D Operating Instructions Manual

Display parameters
Display parameters are represented with four digits preceded by the letter "r". You cannot
change the value of these parameters.
Example:
r0027 is the parameter for the inverter output current. The inverter measures the current and
writes the current value to the parameter. You can display the parameter value, e.g. using an
analog output of the inverter.
Change protection for write parameters
The process of changing parameter values is subject to certain conditions. If an attempt to
change a parameter is rejected by the inverter, this can have a number of causes:
1. The inverter operating state does not allow you to change parameters.
2. In some cases, you may not be able to change certain parameters due to automatic
3. Parameter protection via P0927 has been activated.
For each parameter, the List Manual specifies whether and which conditions apply for
changing the values.

Parameters with follow-on parameterization

When you change certain parameters, the system may automatically change other
parameters accordingly. This makes it much easier to parameterize complex functions.
Example: Parameter P0700 (command source)
Parameter P0700 can be used to switch the command source from the fieldbus to digital
inputs. When the value of P0700 is changed from 6 (command source "fieldbus") to 2
(command source "digital inputs"), other parameter values are changed automatically:
● New functions are assigned to the digital inputs (P0701 ... P0704)
● Inverter control is interconnected with the signals from the digital inputs (P0800, P0801,
For more information about follow-on parameterization for P0700, see the List Manual.

For example, certain parameters can only be changed when the inverter is in
commissioning mode.
follow-on parameterization.
Example: When P0701 = 1, the ON/OFF1 command is connected to digital input 0. As
follow-on parameterization, P0840 (source of the ON/OFF1 command) is assigned value
722.0 (status of digital input 0). which means that P0840 can no longer be changed.
Example: P0927 = 1101 prevents parameters from being changed from the BOP.
