4�4�3 SPI logic
With this interface it is possible to connect the inverter to an external SPI frequency
monitoring device ("Segnale Esterno" is only available when "Italy" is selected in the
country setting).
The interface is configured with the free MaxTalk 2 Pro service software.
Procedure
1. Open the inverter as described in the instruction manual.
