Connections Drawing
There are several configuration options available when pump program is activated. These options
can be configured like in standard program.
Nevertheless, unlike standard program, when pump program is activated, the drive will only allow
setting the options of each digital input (from G4.1.5 to G4.1.10) and will not consider the setting
realized in parameter ‘G4.1.4 DIGIT I MODE’, where digital inputs are set in groups.
This means that user will configure the pump program as he wants, by selecting the functionality
and protections that he needs. For a correct configuration of the inputs when pump program is
active, see chapter G25 Pump Control to get additional information.
