r1282 Vdc_max controller switch-in level (U/f) / Vdc_max on_level
VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
- [V]
Description: Displays the switch-in level for the Vdc_max controller.
If p1294 = 0 (automatic sensing of the switch-in level = off), then the following applies:
AC/AC device: r1282 = 1.15 * sqrt(2) * p0210
DC/AC device: r1282 = 1.15 * p0210
If p1294 = 1 (automatic sensing of the switch-in level = on), then the following applies:
r1282 = Vdc_max - 50.0 V (Vdc_max: Overvoltage threshold of the power unit)
r1282 = Vdc_max - 25.0 V (for 230 V power units)
Notice: If the activation level of the Vdc_max controller is already exceeded in the deactivated state (pulse inhibit) by the DC
link voltage, then the controller can be automatically deactivated (see F07401), so that the drive is not accelerated
the next time that it is activated.
Note: The Vdc_max controller is not switched back off until the DC link voltage falls below the threshold 0.95 * r1282 and
the controller output is zero.
p1283[0...n] Vdc_max controller dynamic factor (U/f) / Vdc_max dyn_factor
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
1 [%]
Description: Sets the dynamic factor for the DC link voltage controller (Vdc_max controller).
100% means that p1290, p1291, and p1292 (gain, integral time, and rate time) are used in accordance with their
basic settings and on the basis of 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 p1283.
If several modules are connected to the DC link, then the dynamic factor must be increased corresponding to the
ratio of the additional capacitances to the capacitance of the module involved.
Note: The pre-setting of the dynamic factor is based on the power units connected to DRIVE-CLiQ. It is assumed that the
power units connected via DRIVE-CLiQ are also electrically connected to the DC link. If this is not the case, then the
dynamic factor must be optimized manually.
p1284[0...n] Vdc_max controller time threshold (U/f) / Vdc_max t_thresh
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: -
Min
0.000 [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.
