2 - Drive initialization. Max duration time: 5 s.
3 - End of drive initialization. The Enable drive terminal (12) is L (0V).
4 - Delay time during which the Enable drive terminal must be L (0V): 1s.
5 - Drive enabling. Terminal 12 is H (+24V).
If at the end of the drive initialization (step 3) or during the 1s delay time the Enable
drive terminal (term. 12) is High (+24V) a fault is detected

1 - Regulation board power-up: Enable terminal (term.12) in any state.
2 - Drive initialization. Max duration time: 5 s.
3 - End of drive initialization.
4 - Delay time during which the Enable drive terminal must be L (0V) and Enable
drive [314] = Disable ( 0 ): 1s. During this time the Process data channels setup
initialization occurs.
5 - Drive enabling. Terminal 12 is H (+24V) and Enable drive [314] = Enable ( 1 ).
If at the end of the drive initialization (step 3) or during the 1s delay time the Enable
drive terminal (term. 12) is High (+24V) and Enable drive [314] = Disable ( 0 ) a fault
is detected.
