5.5.1.3 Setting connection macros
NOTICE
Connection macro settings
When commissioning the converter, 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 converter to accept the parameter settings from both the
currently and the previously selected macros, which may lead to undefined and
unexplainable converter 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 converter. 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.
Note
The wiring diagrams later in this section use PNP control mode as examples.
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.
Connection macro Description Display example
Cn000 Factory default setting. Makes no parameter changes.
The minus sign indicates that this macro
is the currently selected macro.
Cn001 BOP as the only control source
Cn002 Control from terminals (PNP/NPN)
Cn003 Fixed speeds
Cn004 Fixed speeds in binary mode
Cn005 Analog input and fixed frequency
Cn006 External push button control
Cn007 External push buttons with analog setpoint
Cn008 PID control with analog input reference
Cn009 PID control with the fixed value reference
