Parameters 113
31.31 Frequency trip
margin
Defines, together with 30.13 Minimum frequency and 30.14
Maximum frequency, the maximum allowed frequency of the
motor. If the speed (28.01 Frequency ref ramp input) exceeds
the frequency limit defined by parameter 30.13 or 30.14 by
more than the value of this parameter, the drive trips on
the73F0 Overfrequency fault.
WARNING! This function only supervises the speed in
scalar motor control mode. The function is not
effective in vector motor control mode.
Example: If the maximum speed is 40 Hz and speed trip
margin is 10 Hz, the drive trips at 50 Hz.
15.00 Hz
0.00…10000.00 Hz Overfrequency trip margin. See par.
