Siemens SINAMICS G220 - Ramp-Function Generator; Extended Ramp-Function Generator

14.9.11 Ramp-function generator
14.9.11.1 Extended ramp-function generator
Overview
The ramp-function generator reduces the load on the mechanical system of the driven machine.
With the extended ramp-function generator, acceleration and deceleration are not linear.
Rounding at the start and end areas using a selected rounding type can be parameterized to
make the transitions smoother.

Description of function
The extended ramp-function generator limits the change of acceleration (jerk) by rounding the
setpoint. As a result, the torque does not build up suddenly in the motor.

Figure14-70 The extended ramp-function generator in the extended setpoint channel
The ramp-up and ramp-down times of the extended ramp-function generator can be set
independent of each other.
The optimal times depend on your application, and can lie in the range from a few 100ms to
several minutes.
Initial and 󹪝nal rounding allow jerk-free acceleration and braking.
