555 External power control
Via this interface the inverter can receive digital signals for the specification of the set-
point of active and reactive power. It is possible to connect ripple control receivers to this
interface.
The interface is configured with the free MaxTalk 2 Pro service software (see Section 12).
Figure 22 shows the connection of the ripple control receiver to the interface.
