Terminal 29 Mode input
(par. 5-02 =
cable value).
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
Term. 33 High Ref./Feedb. Value
also par. 5-58
Terminal 29 Mode input
(par. 5-02 =
cable value).
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
Term. 33 Low Ref./Feedb. Value
par. 5-57
Function:
Enter the high frequency corresponding to the high motor shaft speed (i.e. high reference value) in
par. 5-58 Term. 33 High Ref./Feedb. Value
Function:
Enter the low reference value [RPM] for the motor shaft speed. This is also the low feedback value,
see also par. 5-52 Term. 29 Low Ref./Feedb. Value
Function:
Enter the high reference value [RPM] for the motor shaft speed. See also par. 5-53
Ref./Feedb. Value
.
Function:
Enter the pulse filter time constant. The low-pass filter reduces the influence on and dampens os-
cillations 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.
