Control signals
The drive can receive its control signals through the digital and analogue inputs, from the control
panel or through serial communications. Using parameters in groups 10, 11, 12 and 16 it is possible
to define sources for start and stop signal, direction, frequency reference, run enable signal, EXT1/
EXT2 selection signal and for fault reset signal.
Figure 29 illustrates this principle, showing how the parameters are used to select sources for
controlling signals.
By selecting application macro using parameter 9902
APP MACRO
the values of the parameters are
set to their macro dependent values. Figure 30 and Figure 31 show how drive’s internal signals are
affected when various macros are selected.
