Function:
Enter the high frequency limit corresponding to the high motor shaft speed (i.e. high reference value) in par.
5-53.
This parameter is available for FC 302 only.
Function:
also par. 5-57. Set terminal 29 to digital output (par. 5-02 =
This parameter is available for FC 302 only.
Function:
Enter the high reference value [RPM] for the motor shaft speed and the high feedback value, see also par.5-58.
Select terminal 29 as a digital output (par. 5-02 =
This parameter is available for FC 302 only.
Function:
Enter the pulse filter time constant. The pulse filter dampens oscillations of the feedback signal, which is an
advantage if there is a lot of noise in the system. A high time constant value results in better dampening but also
increases the time delay through the filter. This parameter is available for FC 302 only.
This parameter cannot be adjusted while the motor is running.
Function:
Enter the low frequency corresponding to the low motor shaft speed (i.e. low reference value) in par. 5-57. Refer
to the diagram in this section.
Function:
Enter the high frequency corresponding to the high motor shaft speed (i.e. high reference value) in par. 5-58.
Function:
5-52.
Function:
Enter the high reference value [RPM] for the motor shaft speed. See also par. 5-53
Value
.
Function:
Enter the pulse filter time constant. The low-pass filter reduces the influence on and dampens oscillations on the
feedback signal from the control.
This is an advantage, e.g. if there is a great amount on noise in the system. This parameter cannot be adjusted
while the motor is running.
