Illustration 3.27 Pulse Input
5-50 Term. 29 Low Frequency
Range:
Function:
100
Hz
*
[0 - 110000
Hz]
Enter the low frequency limit
corresponding to the low motor shaft
speed (that is low reference value) in
parameter 5-52 Term. 29 Low Ref./Feedb.
Value
. Refer to
in this
section.
5-51 Term. 29 High Frequency
Range:
Function:
100 Hz
*
[0 - 110000
Hz]
Enter the high frequency limit
corresponding to the high motor shaft
speed (that is high reference value) in
parameter 5-53 Term. 29 High Ref./Feedb.
Value
.
5-52 Term. 29 Low Ref./Feedb. Value
Range:
Function:
0
*
[-999999.999 -
999999.999 ]
Enter the low reference value limit for
the motor shaft speed [RPM]. This is also
the lowest feedback value, see also
parameter 5-57 Term. 33 Low Ref./Feedb.
Value
5-53 Term. 29 High Ref./Feedb. Value
Range:
Function:
100
*
[-999999.999 -
999999.999 ]
Enter the high reference value [RPM]
for the motor shaft speed and the
high feedback value, see also
parameter 5-58 Term. 33 High Ref./
Feedb. Value
.
5-54 Pulse Filter Time Constant #29
Range:
Function:
100
ms
*
[1 -
1000 ms]
NOTICE
This parameter cannot be adjusted
while the motor is running.
5-54 Pulse Filter Time Constant #29
Range:
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.
5-55 Term. 33 Low Frequency
Range:
Function:
100 Hz
*
[0 - 110000
Hz]
Enter the low frequency corresponding
to the low motor shaft speed (that is
low reference value) in
parameter 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 (that is
high reference value) in
parameter 5-58 Term. 33 High Ref./Feedb.
Value
5-57 Term. 33 Low Ref./Feedb. Value
Range:
Function:
0
*
[-999999.999 -
999999.999 ]
Enter the low reference value [RPM] for
the motor shaft speed. This is also the
low feedback value, see also
parameter 5-52 Term. 29 Low Ref./Feedb.
Value
5-58 Term. 33 High Ref./Feedb. Value
Range:
Function:
100
*
[-999999.999 -
999999.999 ]
Enter the high reference value [RPM]
for the motor shaft speed. See also
parameter 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, and
dampens oscillations on the feedback
signal from the control.
This is an advantage if there is a great
amount of noise in the system.
