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 (i.e. low reference value) in
5-52 Term. 29 Low Ref./Feedb. Value.
Refer to the diagram 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 (i.e. high reference value) in
5-53 Term. 29 High Ref./Feedb. Value.
5-52 Term. 29 Low Ref./Feedb. Value
Range: Function:
0.000 * [-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 5-57 Term. 33 Low
Ref./Feedb. Value.
5-53 Term. 29 High Ref./Feedb. Value
Range: Function:
100.000 * [-999999.999 -
999999.999 ]
Enter the high reference value
[RPM] for the motor shaft speed
and the high feedback value,
see also 5-58 Term. 33 High Ref./
Feedb. Value.
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.
5-54 Pulse Filter Time Constant #29
Range: Function:
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:
100.000 * [-999999.999 -
999999.999 ]
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.
