You can select the menu with the signal parameters for the function generator in

the five operating modes with this softkey.

You enter the signal parameters in the selected displays. These parameters are

managed internally as configuration data rather than machine data, i.e. they are

not initialized when the machine runs up. Data can be input in two different ways:

Manual input

Input by loading of an existing, complete data set with the aid of file functions

Function generator (axis and spindle) – signal parameters

(as from SW 3)

With a scaling value of 100 %, the function generator output signal is

determined by the following signal parameters:

Amplitude/Amplitude 1

This parameter determines the magnitude of the specified setpoint step

This parameter is significant only for the staircase signal form. It determines

the maximum signal amplitude (see waveforms of signal types).

In the disturbing torque, speed setpoint speed loop, speed setpoint position

loop and position setpoint operating modes, stimulation takes place from

standstill or starting at the constant reverse speed set in this parameter.

In the current setpoint operating mode, stimulation takes place from standstill

or starting at the current offset set in this parameter.

The output signal is limited to this value prior to normalization.

This parameter specifies the fundamental frequency of the function generator.
