Operating instructions
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
par. 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 par. 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 par. 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.
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 par. 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 par. 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
par. 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 par. 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. This parame-
ter cannot be adjusted while the motor is
running.
3.7.7 5-6* Pulse Outputs
Parameters for configuring the scaling and output functions of
pulse outputs. The pulse outputs are designated to terminals
27 or 29. Select terminal 27 output in par. 5-01 Terminal 27
Mode and terminal 29 output in par. 5-02 Terminal 29 Mode.
