Function:
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 (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 centre frequency. The
function is the same as for
parameter 30-04 Wobble Jump Frequency [Hz].

Motor in and Flux mode without
feedback. This parameter is
available for FC 302 only.
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.
Function:
[0.05 - 1 s] Time period for detecting the locked

rotor condition. A low parameter
value leads to faster detection.
