Ramp-function generator

Overview
The ramp-function generator in the setpoint channel limits the rate change of the speed
setpoint (acceleration). A reduced acceleration reduces the accelerating torque of the motor.
In this case, the motor reduces the load on the mechanical system of the driven machine.
You can select between two different ramp-function generator types:
• Extended ramp-function generator
The expanded ramp-function generator limits not only the acceleration but also the
change in acceleration (jerk) by rounding the setpoint. In this case, the torque does not
rise suddenly in the motor.
• Basic ramp-function generator
The basic ramp-function generator limits the acceleration, however not the rate the
acceleration changes (jerk).
