15. Function generator
Operating modes of the function generator:
• The function generator can be used to
generate different signal shapes.
• Depending on the mode setting, this setpoint
can then be fed into the control system, for
example as a current setpoint, disturbing
torque or speed setpoint.
• The impact of superimposed control loops is
automatically suppressed.
