backUnit] speed and the high feedback
value, see also
5-58 Term. 33
High Ref./Feedb. Value . Select
terminal 29 as a digital input
(
5-02 Terminal 29 Mode = [0]
input (default) and
5-13 Terminal 29 Digital Input =
applicable value).
This parameter is available for
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
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.
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
*
[-999999.999 -
999999.999 ] 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:
Size related
*
[-999999.999 -
999999.999
ReferenceFeedbackUnit] 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 on the feedback
signal from the control.
This is an advantage, e.g. if there is a
great amount on noise in the system.
NOTE
This parameter cannot be adjusted while the motor is
running.
3.7.6 5-6* Pulse Outputs
These parameters are to configure pulse outputs with their
functions and scaling. Terminal 27 and 29 are allocated to
pulse output via
5-01 Terminal 27 Mode and 5-02 Terminal
29 Mode , respectively.
NOTE
These parameters cannot be adjusted while the motor is
running.
