5-52 Term. 29 Low Ref./Feedb. Value
Range: Function:
0.000 Reference-
FeedbackUnit
*
[-999999.999 -
999999.999
ReferenceFeed-
backUnit]
Enter the low reference
value limit for the motor
shaft speed [RPM]. This is
also the lowest feedback
value, see also 5-57 Term.
33 Low Ref./Feedb. Value .
Set terminal 29 to digital
input ( 5-02 Terminal 29
Mode = input [0] (default)
and 5-13 Terminal 29
Digital Input = applicable
value).
This parameter is
available for the FC 302
only.
5-53 Term. 29 High Ref./Feedb. Value
Range: Function:
Application
dependent
*
[-999999.999 -
999999.999
ReferenceFeed-
backUnit]
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 input ( 5-02 Terminal 29
Mode = input [0] (default) and
5-13 Terminal 29 Digital Input
= applicable value).
This parameter is available for
the FC 302 only.
5-54 Pulse Filter Time Constant #29
Range: Function:
100
ms
*
[1 - 1000
ms]
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 damping, but also
increases the time delay through the filter.
This parameter is available for the FC 302 only.
This parameter cannot be adjusted while the
motor is running.
5-55 Term. 33 Low Frequency
Range: Function:
100 Hz
*
[0 - 110000 Hz] Enter the low frequency corresponding
to the low motor shaft speed (i.e., low
reference value) in 5-57 Term. 33 Low
Ref./Feedb. Value .
5-56 Term. 33 High Frequency
Range: Function:
100 Hz
*
[0 - 110000 Hz] Enter the high frequency
corresponding to the high motor shaft
speed (i.e., high reference value) in
5-58 Term. 33 High Ref./Feedb. Value .
5-57 Term. 33 Low Ref./Feedb. Value
Range: Function:
0.000 N/A
*
[-999999.999 -
999999.999 N/A]
Enter the low reference value
[RPM] for the motor shaft speed.
This is also the low feedback
value, see also 5-52 Term. 29 Low
Ref./Feedb. Value .
5-58 Term. 33 High Ref./Feedb. Value
Range: Function:
Application
dependent
*
[-999999.999 -
999999.999
ReferenceFeed-
backUnit]
Enter the high reference
value [RPM] for the
motor shaft speed. See
also 5-53 Term. 29 High
Ref./Feedb. Value .
5-59 Pulse Filter Time Constant #33
Range: Function:
100 ms
*
[1 - 1000
ms]
Enter the pulse filter time constant. The low-
pass filter reduces the influence on, and
dampens oscillations in, the feedback signal
from the control.
This is an advantage, if, for example, there is
a great amount of noise in the system. This
parameter cannot be adjusted while the
motor is running.
