Parameter Descriptions
5-55 Term. 33 Low Frequency
Range: Function:
100 Hz [0 - 110000 Enter the low frequency
*
Hz] 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 Enter the high frequency
*
Hz] 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:
0.000 [-999999.999 - Enter the low reference value
*
999999.999 ] [RPM] for the motor shaft speed.
This is also the low feedback
value, see also 5-52 Term. 29 Low
Ref./Feedb. Value.

5-59 Pulse Filter Time Constant #33
Range: Function:
100 ms [1 - 1000 Enter the pulse filter time constant. The
*
ms] 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.
