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 N/A* [-999999.999 - 999999.999 N/A] 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 N/
A* [-999999.999 - 999999.999 N/A] 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 in, the feedback signal from the control.
This is an advantage, if, for example, there is a great amount of noise in the system. This parameter
cannot be adjusted while the motor is running.
3.7.8 5-6* Pulse Outputs
Parameters for configuring the scaling and output functions of pulse outputs. The pulse outputs are designated for 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
.
