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 Illustration 3.27 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 lter time constant. The
pulse lter 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 lter.
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 lter time constant. The
low-pass lter reduces the inuence, 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.
