Parameter 5-52 Term. 29 Low Ref./Feedb. Value
Table 319: Parameter 5-52 Term. 29 Low Ref./Feedb. Value
5-52 Term. 29 Low Ref./Feedb. Value
Default value: Size related Parameter type: Range, -999999.999 - 999999.999 Reference- Feed-
backUnit
Setup: All setups
Conversion index: -3
Data type: Int32
Change during operation: True
Enter the low reference value limit for the motor shaft speed [RPM]. This is also the lowest feedback value, see also
parameter 5-57
Term. 33 Low Ref./Feedb. Value
. Set terminal 29 to digital input (
parameter 5-02 Terminal 29 Mode
=
[0] Input
(default) and
parameter
5-13 Terminal 29 Digital Input
= applicable value).
Parameter 5-53 Term. 29 High Ref./Feedb. Value
Table 320: Parameter 5-53 Term. 29 High Ref./Feedb. Value
5-53 Term. 29 High Ref./Feedb. Value
Default value: Size related Parameter type: Range, -999999.999 - 999999.999 Reference- Feed-
backUnit
Setup: All setups
Conversion index: -3
Data type: Int32
Change during operation: True
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 321: Parameter 5-54 Pulse Filter Time Constant #29
5-54 Pulse Filter Time Constant #29
Default value: 100 ms
Parameter type: Range, 1 - 1000 ms
Setup: All setups
Conversion index: -3
Data type: Uint16
Change during operation: False
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 322: Parameter 5-55 Term. 33 Low Frequency
5-55 Term. 33 Low Frequency
Default value: 100 Hz
Parameter type: Range, 0 - 110000 Hz
Setup: All setups
Conversion index: 0
Data type: Uint32
Change during operation: True
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 323: Parameter 5-56 Term. 33 High Frequency
5-56 Term. 33 High Frequency
Default value: Size related
Parameter type: Range, 0 - 110000 Hz
Setup: All setups
Conversion index: 0
Data type: Uint32
Change during operation: True
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
.
