7.3.7.9 Ramp-function generator
Description
The ramp-function generator is used to limit acceleration in the event of abrupt setpoint
changes, which helps prevent load surges throughout the drive train. The ramp-up time
p1120[D] and ramp-down time p1121[D] can be used to set mutually independent
acceleration and deceleration ramps. This allows a controlled transition to be made in the
event of setpoint changes.
The maximum speed p1082[D] is used as a reference value for calculating the ramps from
the ramp-up and ramp-down times. A special adjustable ramp can be set via p1135 for quick
stop (OFF3), e.g. for rapid controlled deceleration when an emergency OFF button is
pressed.
