Parameters 265
Defines, together with
, the maximum allowed frequency of the
motor. If the speed (
) exceeds
the frequency limit defined by parameter
more than the value of this parameter, the drive trips on
the
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.
Selects how the drive reacts when a main cooling fan speed
problem is detected.
An event is triggered according to the value of this parameter
(fault, warning or no action)
• if the rotation speed signal from the fan is lower than the
measured fan maximum speed (determined during the fan
ID run)
• if the measured fan maximum speed is lower than the
predefined minimum value
