172 Program features Example 1Sequence 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 theSequence 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 andafter that the state shifts back to state 3.Parameter Setting Additional information1002 EXT2 COMMANDS SEQ PROG Start, stop, direction commands for EXT21102 EXT1/EXT2 SEL EXT2 EXT2 activation1106 REF2 SELECT SEQ PROG Sequence programming output as REF21601 RUN ENABLE NOT SEL Deactivation of Run enable2102 STOP FUNCTION RAMP Ramp stop2201 ACC/DEC 1/2 SEL SEQ PROG Ramp as defined by parameter 8422/…/8452.8401 SEQ PROG ENABLE ALWAYS Sequence programming enabled8402 SEQ PROG START DI1 Sequence programming activation throughdigital input (DI1)8404 SEQ PROG RESET DI1(INV) Sequence programming reset (ie, reset to state1, when DI1 signal is lost (1 -> 0)State change triggerSeq. start50 Hz0 Hz-50 HzDI1DI2ST1 ST2 ST3 ST4 ST3
