p1284[0...n]
Vdc_max controller time threshold (U/f) / Vdc_max t_thresh
Access level: 3
Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T, U
Scaling: -
Dynamic index: DDS, p0180
Unit group: -
Unit selection: -
Function diagram: -
Min:
0.000 [s]
Max:
300.000 [s]
Factory setting:
4.000 [s]
Description:
Sets the monitoring time for the Vdc_max controller.
If the down ramp of the speed setpoint is held for longer than the time set in p1284, then fault F07404 is output.

Function diagram: 6320, 6854
Min:
65 [%]
Max:
150 [%]
Factory setting:
76 [%]
Description:
Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1286[V] = p1285[%] * sqrt(2) * p0210
WARNING
An excessively high value may adversely affect normal drive operation.
r1286
Vdc_min controller switch-in level (kinetic buffering) (U/f) / Vdc_min on_level

Function diagram: 6320, 6854
Min:
- [V]
Max:
- [V]
Factory setting:
- [V]
Description:
Displays the switch-in level for the Vdc_min controller (kinetic buffering).
Note
The Vdc_min controller is not switched back off until the DC link voltage rises above the threshold 1.05 * r1286 and the
controller output is zero.

Vdc_min controller dynamic factor (kinetic buffering) (U/f) / Vdc_min dyn_factor
Access level: 3
Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U

Function diagram: 6320, 6854
Min:
1 [%]
Max:
10000 [%]
Factory setting:
100 [%]
Description:
Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
100% means that p1290, p1291, and p1292 (gain, integral time, and rate time) are used corresponding to their basic
settings and based on a theoretical controller optimization.
If subsequent optimization is required, this can be carried out using the dynamic factor. In this case, p1290, p1291, and
p1292 are weighted with the dynamic factor p1287.
