Parameter Function
P2946 Wobble signal ampli-
tude [%]
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 out-
put.
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
Sets the value for decrement step at the end of the positive signal period. The amplitude of the step is
dependant upon the signal amplitude as follows:
Amplitude of signal decrement step = P2947 * P2946
P2948 Wobble signal incre-
ment step
Sets the value for the increment step at the end of the negative signal period. The amplitude of the incre-
ment step is dependant upon the signal amplitude as follows:
Amplitude of signal increment step = P2948 * P2946
P2949 Wobble signal pulse
width [%]
Sets the relative widths of the rising and falling pulses. The value in P2949 sets the proportion of the wob-
ble 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.
r2955 CO: Wobble signal
