The delta frequency determines the magnitude of the wobble frequency. The delta frequency is superimposed on the center fre-
quency.
Parameter 30-01 Wobble Delta Frequency [Hz]
contains both the positive and negative delta frequency. The setting of
param-
eter 30-01 Wobble Delta Frequency [Hz]
must thus not exceed the setting of the center frequency. The initial ramp-up time from
standstill until the wobble sequence runs is determined in
parameter group 3-1* References
.
Parameter 30-02 Wobble Delta Freqeuncy [%]
Table 695: Parameter 30-02 Wobble Delta Freqeuncy [%]
30-02 Wobble Delta Freqeuncy [%]
Default Value: 25%
Parameter Type: Range, 0 - 100%
Setup: All set-ups
Conversion Index: 0
Data Type: Uint8
Change during operation: True
The delta frequency can also be expressed as a percentage of the center frequency and can thus be maximum 100%. The function is
the same as for
parameter 30-01 Wobble Delta Frequency [Hz]
.

The jump frequency is used to compensate for the inertia in the traverse system. If a jump in the output frequency is required at the
boundaries of the wobble sequence, the frequency jump is set in this parameter. If the traverse system has a very high inertia, a high
jump frequency may create a torque limit warning or trip or an overvoltage warning or trip. This parameter can only be changed in
stop mode.
