Selection of function generator parameterization “Signal types with operating
modes”
You can select the menu with the signal parameters for the function generator in
the five operating modes with this softkey.
Note 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:
S
Manual input
S
Input by loading of an existing, complete data set with the aid of file functions
9.3.1 Function generator (axis and spindle) – signal parameters
(as from SW 3)
Measurement With a scaling value of 100 %, the function generator output signal is
parameter settings determined by the following signal parameters:
S
Amplitude/Amplitude 1
This parameter determines the magnitude of the specified setpoint step
change.
S
Amplitude 2
This parameter is significant only for the staircase signal form. It determines
the maximum signal amplitude (see waveforms of signal types).
S
Offset
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.
S
Limitation
The output signal is limited to this value prior to normalization.
S
Period
This parameter specifies the fundamental frequency of the function generator.
S
Pulse width
See Section “Waveforms of signal types”.
S
Bandwidth
See Section “Frequency response measurement”.
