4.3.3 Setting connection macros
CAUTION
When commissioning the inverter, the connection macro setting is a one-off setting. Make
sure that you proceed as follows before you change the connection macro setting to a
value different from your last setting:
1. Do a factory reset (P0010 = 30, P0970 = 1)
2. Repeat the quick commissioning and change the connection macro
Failure to observe may cause the inverter to accept the parameter settings from both the
currently and the previously selected macros, which may lead to undefined and
unexplainable inverter operation.
However, communication parameters P2010, P2011, P2021 and P2023 for connection
macros Cn010 and Cn011 are not reset automatically after a factory reset. If necessary,
reset them manually.
After changing P2023 setting for Cn010 or Cn011, power-cycle the inverter. During the
power-cycle, wait until LED has gone off or the display has gone blank (may take a few
seconds) before re-applying power.
Functionality
This menu selects which macro is required for standard wiring arrangements. The default
one is "Cn000" for connection macro 0.
All connection macros only change the CDS0 (command data set 0) parameters. The CDS1
parameters are used for the BOP control. For more information about the CDS parameters,
see SINAMICS V20 Inverter Operating Instructions.
