The maximum speed p1082 is used as a reference value for calculating the ramps from
the ramp-up and ram
p-down time. For a quick stop (OFF3), a special adjustable ramp is
available via the ramp-down time p1135 (for example, for quick, controlled stopping after an
EMERGENCY OFF button has been pressed).
The following versions are available:
• Basic ramp-function generator (p1115=0)
• Extended ramp-function generator (p1115=1)
Basic ramp-function generator
