Programmable Inputs (Sequence start)
When sequence start is going to be used, the wiring should be according to Figure 18 or Figure 19.
The start command (Terminal 5, 6 and 7) must be maintained during th complete starting sequence;
otherwise, a direct stop will be performed.
Soft stop can only be performed for the motor currently fed by the softstarter and will be achieved by
opening the Stop command (Terminal 4).
