50 Hz
0 Hz
-50 Hz
DI1
DI2
Sequence programming is activated by digital input DI1.
ST1: Drive is started in reverse direction with -50 Hz reference and 10 s ramp time.
State 1 is active for 40 s.
ST2: Drive is accelerated to 20 Hz with 60 s ramp time. State 2 is active for 120 s.
ST3: Drive is accelerated to 25 Hz with 5 s ramp time. State 3 is active until the
sequence programming is disabled or until booster start is activated by DI2.
ST4: Drive is accelerated to 50 Hz with 5 s ramp time. State 4 is active for 200 s and
after that the state shifts back to state 3.
