Principle State Machine
The Inverter’s reaction to commands is defined by a state machine. This determines which
commands provide the demanded action, and in which sequence.
Main Sequencing States
The main sequencing state of the unit is indicated by an enumerated value given by the parameter
MAIN SEQ STATE under SEQUENCING LOGIC menu at level 4.
