Function:
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].
Function:
[ 0.005 - 5.000 This parameter determines the
slope of the jump ramp at the
maximum and minimum wobble
frequency.
Function:

This parameter is available for
FC 302 only.
High starting torque current for PM
motor in VVC
without feedback.
NOTICE
This parameter is available for FC 302 only.
Available for PM motors only, in flux sensorless mode
and VVC + open-loop mode.
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.
Function:
[0.05 - 1 s] Time period for detecting the locked
*
rotor condition. A low parameter
value leads to faster detection.
