1-15 Low Speed Filter Time Const.

Default value: Size related Parameter type: Range (0.01–20.00 s)

Setup: All setups Conversion index: -2

Data type: Uint16 Change during operation: True

This time constant is used below 10% rated speed. Obtain quick control through a short damping time constant. However, if this value is

too short, the control becomes unstable.

1-16 High Speed Filter Time Const.

Default value: Size related Parameter type: Range (0.01–20.00 s)

Setup: All setups Conversion index: -2

Data type: Uint16 Change during operation: True

This time constant is used above 10% rated speed. Obtain quick control through a short damping time constant. However, if this value is

too short, the control becomes unstable.

1-17 Voltage Filter Time Const.

Default value: Size related Parameter type: Range (0.001–1.000 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.

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 the "Isd" current in no load situations to achieve a smoother motor operation.

4.2.3 1-2* Motor Data

This parameter group comprises input data from the nameplate on the connected motor.

 NOTICE

Changing the value of these parameters affects the setting of other parameters.

1-20 Motor Power

Default value: Size related Parameter type: Option

Setup: All setups Conversion index: –

Data type: Uint8 Change during operation: False
