Parameter Descriptions
NOTE
This parameter can be set while running.
NOTE
The setting of "Center Frequency" takes place via the
normal reference handling parameters, 3-1*
30-01 Wobble Delta Frequency [Hz]
Range: Function:
5.0 [0.0 - The delta frequency is determining the
Hz 25.0 Hz] magnitude of the wobble frequency. The delta
*
frequency is superimposed on the center
frequency. Parameter 30-01 is selecting both the
positive and negative delta frequency. The
setting of parameter 30-01 must thus not be
higher than the setting of the center frequency.
The initial ramp up time from standstill until the
wobble sequence is running is determined by
parameters 3-1*.
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 par. 30-01.
30-03 Wobble Delta Freq. Scaling Resource
Option: Function:
Select which drive input should be
used to scale the delta frequency
setting.

30-04 Wobble Jump Frequency [Hz]
Range: Function:
0.0 [Applica- The jump frequency is used to compensate
Hz tion for the inertia in the traverse system. If a
*
dependant] jump in the output frequency is required in
the top and in the bottom 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
(warning/alarm 12) or an over voltage
warning or trip (warning/alarm 7). This

Function:
parameter can only be changed in stop-
mode
Function:
[0 - 100 %] The jump frequency can also be expressed as
*
percentage of the center frequency. The
function is the same as for par. 30-04.
[Application This parameter determines the
dependant] slope of the jump ramp at the
*
max. and min. wobble frequen-
cy.
Function:
[1.0 - 1000.0 s] This parameter determines the wobble
*
sequence period. This parameter can
only be changed in stop-mode.
