Parameter Descriptions
30-04 Wobble Jump Frequency [Hz]
Range: Function:
0 Hz [ 0 - The jump frequency is used to compensate for
*
20.0 Hz] 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 - The jump frequency can also be expressed as
*
100 %] 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:
Size related [ 0.005 - 5.000 s]
*
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.
30-09 Wobble Random Function
Option:
[0] Off
*
[1] On
30-10 Wobble Ratio
Range: Function:
1 [0.1 - 10] If the ratio 0.1 is selected: t
*
greater than t .
up
If the ratio 10 is selected: t

down
30-11 Wobble Random Ratio Max.
Range: Function:
10 [ par. 17-53 - 10] Enter the maximum allowed wobble
*
ratio.

30-12 Wobble Random Ratio Min.
Range: Function:
0.1 [ 0.1 - par. 30-11] Enter the minimum allowed wobble
*
ratio.
30-19 Wobble Delta Freq. Scaled
Range: Function:
0 Hz [0 - 1000 Hz] Readout parameter. View the actual
*
wobble delta frequency after scaling has
been applied.
3.21.3 30-2* Adv. Start Adjust
30-20 High Starting Torque Time [s]
Range: Function:
NOTICE
Size related [0 - 60 s]
*
This parameter is available for FC
302 only.
High starting torque time for PM motor
in flux control principle without
feedback.
30-21 High Starting Torque Current [%]
Range: Function:
NOTICE
Size related [ 0 -
*
200.0 %]
This parameter is available for
FC 302 only.
High starting torque current for PM
motor in VVC
without feedback.
30-22 Locked Rotor Protection
Option: Function:
NOTICE
This parameter is available for FC 302 only.
Available for PM motors only, in flux sensorless mode
and VVC + open-loop mode.
[0] Off
[1] On Protects the motor from the locked rotor condition. The
control algorithm detects a possible locked rotor
condition in the motor and trips the frequency
converter to protect the motor.
30-23 Locked Rotor Detection Time [s]
Range: Function:
Size related [0.05 - 1 s] Time period for detecting the locked
*
rotor condition. A low parameter
value leads to faster detection.
