Function:
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.
Function:
Select which drive input should be used to scale the delta frequency setting.
FC 302 only
Function:
The jump frequency is used to compensate for the inertia in the traverse system. If a 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 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 par. 30-04.
Function:
This parameter determines the slope of the jump ramp at the max. and min. wobble frequency.
Function:
This parameter determines the wobble sequence period. This parameter can only be changed in
stop-mode.
Wobble time = t + t
up down
Function:
Defines the individual up- and down times for each wobble cycle.
Function:
