P2946
Wobble signal ampli-
tude [%]
0.000 - 0.200 0.000 T - - Float 2
Sets the value for the amplitude of the wobble-signal as a proportion of the present ramp function genera-
tor (RFG) output. The value of P2946 is multiplied by the output value of the RFG then added to RFG output.
For example, if the RFG output is 10 Hz, and P2946 has a value of 0.100, the wobble signal amplitude will
be 0.100 * 10 = 1 Hz. This means that the RFG output will therefore wobble between 9 Hz and 11 Hz.
P2947
Wobble signal decre-
ment step
0.000 - 1.000 0.000 T - - Float 2
Sets the value for decrement step at the end of the positive signal period. The amplitude of the step is
dependent upon the signal amplitude as follows:
Amplitude of signal decrement step = P2947 * P2946
P2948
Wobble signal incre-
ment step
0.000 - 1.000 0.000 T - - Float 2
Sets the value for the increment step at the end of the negative signal period. The amplitude of the incre-
ment step is dependent upon the signal amplitude as follows:
Amplitude of signal increment step = P2948 * P2946
P2949
Wobble signal pulse
width [%]
0 - 100 50 T - - U16 2
Sets the relative widths of the rising and falling pulses. The value in P2949 sets the proportion of the wobble
period (determined by P2945) allocated to the rising pulse, the remainder of the time is allocation to the falling pulse.
A value of 60% in P2949 means that 60% of the wobble period the wobble output will be rising. For the
remaining 40% of the wobble period the wobble output will be falling.
