Danfoss VLT Refrigeration Drive FC-103P90KT4 [70/203] 6 pulse outputs

Danfoss VLT Refrigeration Drive FC-103P11KT4 [70/203] 6 pulse outputs
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.
NOTE
This meter 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 * [-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 * [-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.
