Setting the wobble generator
Functionality
The wobble generator executes predefined periodical disruptions superimposed on the main
setpoint for technological usage in the fiber industry. The wobble function can be activated
via P2940. It is independent of the setpoint direction, thus only the absolute value of the
setpoint is relevant. The wobble signal is added to the main setpoint as an additional
setpoint. During the change of the setpoint the wobble function is inactive. The wobble signal
is also limited by the maximum frequency (P1082).

BI: Release wobble function
This parameter defines the source to release the wobble
function.
Factory default: 0.0
P2945
Wobble signal frequency [Hz]
This parameter sets the frequency of the wobble signal.
Range: 0.001 ... 10.000 (factory default: 1.000)
P2946
Wobble signal amplitude [%]
This parameter sets the value for the amplitude of the wobble-
signal as a proportion of the present ramp function generator
(RFG) output.
Range: 0.000 ... 0.200 (factory default: 0.000)
