Programming Guide
Parameter 5-53 Term. 29 High Ref./Feedb. Value
Table 367: Parameter 5-53 Term. 29 High Ref./Feedb. Value
5-53 Term. 29 High Ref./Feedb. Value
Default value: Size related
Conversion index: -3
Enter the high reference value [RPM] for the motor shaft speed and the high feedback value, see also parameter 5-58 Term. 33 High
Ref./Feedb. Value. Select terminal 29 as a digital input (parameter 5-02 Terminal 29 Mode = [0] Input (default) and parameter 5-13 Ter-
minal 29 Digital Input = applicable value).
Parameter 5-54 Pulse Filter Time Constant #29
Table 368: Parameter 5-54 Pulse Filter Time Constant #29
5-54 Pulse Filter Time Constant #29
Default value: 100 ms
Conversion index: -3
Enter the pulse filter time constant. The pulse filter dampens oscillations of the feedback signal. If there is much noise in the system
this is an advantage. A high time constant value results in better dampening but also increases the time delay through the filter.
Parameter 5-55 Term. 33 Low Frequency
Table 369: Parameter 5-55 Term. 33 Low Frequency
5-55 Term. 33 Low Frequency
Default value: 100 Hz
Conversion index: 0
Enter the low frequency corresponding to the low motor shaft speed (that is low reference value) in parameter 5-57 Term. 33 Low
Ref./Feedb. Value.
Parameter 5-56 Term. 33 High Frequency
Table 370: Parameter 5-56 Term. 33 High Frequency
5-56 Term. 33 High Frequency
Default value: Size related
Conversion index: 0
Enter the high frequency corresponding to the high motor shaft speed (that is high reference value) in parameter 5-58 Term. 33 High
Ref./Feedb. Value.
Parameter 5-57 Term. 33 Low Ref./Feedb. Value
Table 371: Parameter 5-57 Term. 33 Low Ref./Feedb. Value
5-57 Term. 33 Low Ref./Feedb. Value
Default value: Size related
Conversion index: -3
Enter the low reference value [RPM] for the motor shaft speed. This is also the low feedback value, see also parameter 5-52 Term. 29
Low Ref./Feedb. Value.
