5-50 Term. 29 Low Frequency
Range: Function:
100Hz
*
[0 - 110000 Hz] Enter the low frequency limit corresponding to the low motor
shaft speed (i.e. low reference value) in par. 5-52. Refer to the
diagram in this section.
5-51 Term. 29 High Frequency
Option: Function:
[100Hz]
*
0 - 110000 Hz Enter the high frequency limit corresponding to the high motor
shaft speed (i.e. high reference value) in par. 5-53.
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.
5-53 Term. 29 High Ref./Feedb. Value
Range: Function:
100.000
*
[Par. 5-52 -
1000000.000]
Enter the high reference value [RPM] for the motor shaft speed
and the high feedback value, see also par. 5-58.
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:
100Hz
*
[0 - 110000 Hz] Enter the low frequency corresponding to the low motor shaft
speed (i.e. low reference value) in par. 5-57. Refer to the dia-
gram in this section.
5-56 Term. 33 High Frequency
Range: Function:
100Hz
*
[0 - 110000 Hz] Enter the high frequency corresponding to the high motor shaft
speed (i.e. high reference value) in par. 5-58.
