2.2 List of parameters
Description:
Sets the configuration for the DC link voltage controller.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
For bit 00:
De-activate the ramp-up for Vdc_min control.
For drives with a mechanical system that can oscillate and high moment of inertia, the speed can be more quickly
tracked.
For bit 02:
When the line supply returns, normal operation is resumed earlier, and the system does not wait until the Vdc min
controller reaches the setpoint speed.
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:
r1282 = 1.15 * sqrt(2) * p0210 (supply voltage)
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)
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
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.
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.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
