p1243[0...n] Vdc_max controller dynamic factor / Vdc_max dyn_factor
G120X_DP
(Vdc_max),
G120X_PN
(Vdc_max),
G120X_USS
(Vdc_max)
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6220
Min:
1 [%] Max:
10000 [%] Factory setting:
100 [%]
Description: Sets the dynamic factor for the DC link voltage controller (Vdc_max controller).
100% means that p1250, p1251, and p1252 (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 p1250, p1251,
p1252 are weighted with the dynamic factor p1243.
p1245[0...n] Vdc_min controller switch-in level (kinetic buffering) / Vdc_min on_level
G120X_DP (Vdc_min),
G120X_PN (Vdc_min),
G120X_USS
(Vdc_min)
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
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:
r1246[V] = p1245[%] * sqrt(2) * p0210
Dependency: See also: p0210
WARNING
An excessively high value possibly negatively influences normal drive operation, and can mean that after the line
supply returns, the Vdc minimum control can no longer be exited.
r1246 Vdc_min controller switch-in level (kinetic buffering) / Vdc_min on_level
G120X_DP (Vdc_min),
G120X_PN (Vdc_min),
G120X_USS
(Vdc_min)
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2001 Dynamic index: -
Unit group: - Unit selection: - Function diagram: 6220
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 * p1246 and the
controller output is zero.

G120X_USS (PM330,

Description: Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
100% means that p1250, p1251, and p1252 (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 p1250, p1251,
p1252 are weighted with the dynamic factor p1247.
