ST8 (error state): Drive is stopped with ramp pair 1. Relay output RO is activated. If
sequence programming is deactivated by 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%, i.e scaled AI1 value must be between
15...85%. If AI1 = 0 reference = 0% + 35% -50% = -15% < 0%.
