Function:
system has a very high inertia a high jump
frequency may create a torque limit warning or
trip (warning/alarm 12) or an overvoltage warning
or trip (warning/alarm 7). This parameter can only
be changed in stop-mode
Function:
The jump frequency can also be expressed as
percentage of the center frequency. The
function is the same as for 30-04 Wobble Jump
Frequency [Hz].
[ 0.005 - 5.000 s]
Function:
This parameter determines the wobble
sequence period. This parameter can only be
changed in stop-mode.
Wobble time = t + t
