4.4.2 Factory setting of the frequency inverter
Default command and setpoint sources
Inverters used in automation solutions have the appropriate fieldbus interfaces. These
inverters are preset in the factory so that the appropriate control and status signals can be
exchanged via the fieldbus interface.
Inverters without a fieldbus interface are pre-set in the factory so that the digital and analog
and input output signals are exchanged via terminals.
For instance, if you do not want to control an inverter equipped with a fieldbus interface via
the fieldbus, but instead using switches and pushbuttons that are connected to the digital
inputs, then you must change parameter P0700 as follows.
Table 4- 2 Command and setpoint sources
Parameters Description
P0700 = 2 or 6 Select the command source
2: Digital intputs (P0701 … P0709) (factory setting for CUs without fieldbus interface)
6: Fieldbus (P2050 … P2091), (factory setting for CUs with fieldbus interface)
P1000 = 2 or 6 Select the setpoint source
2: Analog setpoint (factory setting for CUs without fieldbus interface)
6: Fieldbus (factory setting for CUs with fieldbus interface)
