Parameter list
Note:
The pre-setting of the dynamic factor is based on the power modules connected at DRIVE-CLiQ. It is assumed that
the power module, connected via DRIVE-CLiQ is also electrically connected to the DC link. If this is not the case,
then the dynamic factor must be optimized manually.
p1250[0...n]
Vdc controller proportional gain / Vdc_ctrl Kp
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Functions
Min
0.00
Description:
Sets the proportional gain for the Vdc controller (DC link voltage controller).
Dependency:
The effective proportional gain is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note:
The gain factor is proportional to the capacitance of the DC link. The parameter is preset to a value that is optimally
adapted to the capacitance of the individual motor module. The capacitances of the other power modules, which
are connected to the DC link, can be taken into account using the dynamic factor (p1247 or p1243).
p1251[0...n]
Vdc controller integral action time / Vdc_ctrl Tn
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Functions
Min
0 [ms]
Description:
Sets the integral action time for the Vdc controller (DC link voltage controller).
Dependency:
The effective integral action time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note:
An integral action time is normally not required for single axis drives. For multi-axis drives on the other hand, it may
be possible to compensate for interference from other axes using the integral action time (integral component) . An
integral action time of 0 (default) de-activates the controller.
p1252[0...n]
Vdc controller derivative-action time / Vdc_ctrl t_deriv.
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Functions
Min
0 [ms]
Description:
Sets the derivative-action time constant for the Vdc controller (DC link voltage controller).
Dependency:
The effective derivative action time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note:
During controlled operation this parameter has no effect.
