3.2.1

Function generator

Description
The ramp-function generator can be used, for example, for the following tasks:
● To measure and optimize control loops.
● To compare the dynamic response of coupled drives.
● To specify a simple traversing profile without a traversing program.
The ramp-function generator can be used to generate different signal shapes.
In the connector output operating mode (r4818), the output signal can be injected into the
control loop via the BICO interconnection.
In servo operation and depending on the mode set, this setpoint can also be injected into the
control structure as a current setpoint, disturbing torque, or speed setpoint, for example. The
impact of superimposed control loops is automatically suppressed.
