Parameter 1-16 High Speed Filter Time Const.
Table 74: Parameter 1-16 High Speed Filter Time Const.
1-16 High Speed Filter Time Const.
Default value: Size related
Parameter type: Range, 0.01 - 20 s
Setup: All setups
Conversion index: -2
Data type: Uint16
Change during operation: True
The time constant is used above 10% rated speed. Obtain quick control through a short dampening time constant. However, if this
value is too short, the control becomes unstable.
Parameter 1-17 Voltage Filter Time Const.
Table 75: Parameter 1-17 Voltage Filter Time Const.
1-17 Voltage Filter Time Const.
Default value: Size related
Parameter type: Range, 0.001 - 2 s
Setup: All setups
Conversion index: -3
Data type: Uint16
Change during operation: True
Reduces the influence of high frequency ripple and system resonance in the calculation of supply voltage. Without this filter, the
ripples in the currents can distort the calculated voltage and affect the stability of the system.
Parameter 1-18 Min. Current at No Load

1-18 Min. Current at No Load
Default value: 0%
Parameter type: Range, 0 - 50%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: True
Adjust this parameter to achieve a smoother motor operation.
