Function:
[ 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.
Function:
[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].
Function:
[ 0.005 - This parameter determines the
slope of the jump ramp at the
maximum and minimum wobble
frequency.
Function:
[1 - 1000 s] This parameter determines the
wobble sequence period. This
parameter can only be changed in
stop mode.
