Parameter Descriptions
30-04 Wobble Jump Frequency [Hz]
Range: Function:
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
overvoltage warning or trip (warning/alarm 7).
This parameter can only be changed in stop-
mode
30-05 Wobble Jump Frequency [%]
Range: Function:
0 % [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].
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

*
ratio.

*
ratio.
30-19 Wobble Delta Freq. Scaled
Range: Function:

*
wobble delta frequency after scaling has
been applied.
3.20.3 30-2* Adv. Start Adjust
30-20 High Starting Torque Time [s]
Range: Function:
Size related [0 - 60 s] High starting torque time for PM-Motor
*
in Flux mode without feedback. This
parameter is available for FC 302 only.
30-21 High Starting Torque Current [%]
Range: Function:
Size related [ 0 - 200.0 %] High starting torque current for
*
PM-Motor in and Flux mode
without feedback. This parameter is
available for FC 302 only.
30-22 Locked Rotor Protection
This parameter is available for FC 302 only. Available for PM
motors only, in Flux Sensorless mode and VVC Plus open loop
mode.
Option: Function:
[0] Off
*
[1] On Protects the motor from the Locked Rotor condition.
The control algorithm detects a possible locked rotor
condition in motor and trips the frequency converter
to protect the motor.
30-23 Locked Rotor Detection Time [s]
This parameter is available for FC 302 only. Available for PM
motors only, in Flux Sensorless mode and VVC Plus open loop
mode.
Range: Function:
Size related [0.05 - 1 s] Time period for detecting the locked
*
rotor condition. A low parameter
value leads to faster detection.
30-24 Locked Rotor Detection Speed Error [%]
This parameter is available for FC 302 only.
Range:
25 % [0 - 100 %]
