ST2: Drive is accelerated with AI1 + 15% (AI1 + 65% - 50%) reference and 1.5 s
ramp time. State shifts to the next state when reference is reached. If reference is not
reached within 2 s, state shifts to state 8 (error state).
ST3: Drive is decelerated with AI1 + 10% (AI1 + 60% - 50%) reference and 0 s ramp
1)
time
. State shifts to the next state when reference is reached. If reference is not
reached within 0.2 s, state shifts to state 8 (error state).
ST4: Drive is decelerated with AI1 - 15% (AI1 + 35% -50%) reference and 1.5 s ramp
time. State shifts to the next state when reference is reached. If reference is not
reached within 2 s, state shifts to state 8 (error state).
ST5: Drive is accelerated with AI1 -10% (AI1 + 40% -50%) reference and 0 s ramp
1)
time
. State shifts to the next state when reference is reached. Sequence counter
value is increased by 1. If sequence counter elapses, state shifts to state 7 (sequence
completed).
ST6: Drive reference and ramp times are the same as in state 2. Drive state shifts
immediately to state 2 (delay time is 0 s).
ST7 (sequence completed): Drive is stopped with ramp pair 1. Digital output DO is
activated. If Sequence programming is deactivated by the falling edge of digital input
DI1, state machine is reset to state 1. New start command can be activated by digital
input DI1 or by digital inputs DI4 and DI5 (both inputs DI4 and DI5 must be
simultaneously active).
ST8 (error state): Drive is stopped with ramp pair 1. Relay output RO is activated. If
Sequence programming is deactivated by the falling edge of digital input DI1, state
machine is reset to state 1. New start command can be activated by digital input DI1
or by digital inputs DI4 and DI5 (both inputs DI4 and DI5 must be simultaneously
active).
1)
0 second ramp time = drive is accelerated/decelerated as rapidly as possible.
2)
State reference must be between 0...100%, ie scaled AI1 value must be between
15...85%. If AI1 = 0, reference = 0% + 35% -50% = -15% < 0%.
