The "ramp-function generator" function is used to limit acceleration in the event of abrupt
setpoint changes and thus helps prevent load surges during drive operation.
Description of function
The ramp-up time p1120 and ramp-down time p1121 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 is used as a reference value for calculating the ramps from
the ramp-up and ramp-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
The basic ramp-function generator is characterized by the following features:
• Ramp-up time T
