Parameters 261
29.21 DC voltage
integration time
Defines the integration time for the DC voltage reference PI
controller.
Setting the integration time to zero disables the I-part of the
controller.
0.1646 s
0.0000 …
60.0000 s
Integration time. 10000 = 1 s
29.25 DC capacitance
source
Selects the source of the total DC circuit capacitance value.
The value is used in DC voltage reference calculation.
Note: This parameter cannot be changed while the drive is
running.
Copy from
database
Copy from
database
DC capacitance value is taken from an internal database
according to drive type.
0
User value The DC capacitance value is read from parameter 29.26 Used
DC capacitance.
1
29.26 Used DC
capacitance
Defines the DC circuit capacitance when parameter 29.25 DC
capacitance source is set to User value.
Note: This parameter cannot be changed while the drive is
running.

1000.000 mF
User-specified DC capacitance. 100 = 1 mF
29.70 Speed data point 1 Parameters 29.70…29.79 define a maximum torque limitation
curve as a function of speed. The limit is applied before the
reference is forwarded to the torque controller.
This parameter defines the speed at the first point of the
curve. The curve is linear between 0 rpm and this speed.
400.00 rpm
0.00 …
30000.00 rpm
Speed at 1st point of curve. 1 = 1 rpm
29.71 Torque data point 1 Defines the maximum torque at the first point of the limitation
curve.
300.0%
0.0 … 1600.0% Maximum torque at 1st point of curve. 1 = 1%
29.72 Speed data point 2 Defines the speed at the second point of the curve. 800.00 rpm
0.00 …
30000.00 rpm
Speed at 2nd point of curve. 1 = 1 rpm
29.73 Torque data point 2 Defines the maximum torque at the second point of the
limitation curve.
300.0%
0.0 … 1600.0% Maximum torque at 2nd point of curve. 1 = 1%
