30-01 Wobble Delta Frequency [Hz]
Range:
Function:
5 Hz
*
[0 -
25 Hz]
The delta frequency determines the magnitude of
the wobble frequency. The delta frequency is
superimposed on the center frequency.
Parameter 30-01 Wobble Delta Frequency [Hz]
contains both the positive and negative delta
frequency. The setting of
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

30-02 Wobble Delta Frequency [%]
Range:
Function:
25 %
*
[0 -
100 %]
The delta frequency can also be expressed as
percentage of the center frequency and can
thus be maximum 100%. The function is the
same as for

30-04 Wobble Jump Frequency [Hz]
Range:
Function:
0 Hz
*
[ 0 -
20.0 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.
30-05 Wobble Jump Frequency [%]
Range:
Function:
0 %
*
[0 -
100 %]
The jump frequency can also be expressed as
percentage of the center frequency. The
function is the same as for
parameter 30-04 Wobble Jump Frequency [Hz]
30-06 Wobble Jump Time
Range:
Function:
Size related
*
[ 0.005 - 5.000
s]
This parameter determines the
slope of the jump ramp at the
maximum and minimum wobble
frequency.
30-07 Wobble Sequence Time
Range:
Function:
10 s
*
[1 - 1000 s] This parameter determines the wobble
sequence period. This parameter can only be
changed in stop mode.
Wobble time = t

30-08 Wobble Up/ Down Time
Range:
Function:
5 s
*
[0.1 - 1000 s] Defines the individual up and down times
for each wobble cycle.

ratio.
30-12 Wobble Random Ratio Min.
Range:
Function:
0.1
*
[ 0.1 - par. 30-11 ] Enter the minimum allowed wobble
ratio.
