Description:
Sets the configuration of the controller for the DC link voltage (Vdc controller) in the U/f operating mode.
Value:
0:
Inhib Vdc ctrl
1:
Enable Vdc_max controller
2:
Enable Vdc_min controller (kinetic buffering)
3:
Enable Vdc_min controller and Vdc_max controller
4:
Activate Vdc_max monitoring
5:
Activate Vdc_min monitoring
6:
Activate Vdc_min monitoring and Vdc_max monitoring
Warning:
When the Vdc_max controller is active, the motor can be accelerated (e.g. by driving loads or as a result of high DC
link voltages). This can be caused by other drives that are operating on a common DC link busbar.
Caution:
If several drives are operated from the same DC link busbar, then it is recommended that the Udc control is only
activated for the drives with relatively high moments of inertia.
If the Udc controls for various drives are simultaneously active, then they can mutually influence one another. In this
case, the controller dynamic performance should be reduced or the Udc control of individual drives should be
deactivated.
Drives with Udc control must be able to brake and accelerate independently of one another.
Note:
For p1280 = 4, 5, 6:
When the threshold in r1282 or r1286 is reached, the DC link voltage monitoring initiates a fault (F07403 or F07404)
with a response and therefore reduces additional negative effects on the DC link voltage.
If a braking resistor is connected to the DC link, then the Vdc_max control should be disabled.
For p1280 = 1, 3:
Only U/f control: When the Vdc max controller is active, fault F07404 is initiated if the speed setpoint ramp is stopped
(held) longer than the time set in p1284.
Description:
Sets the configuration for the DC link voltage controller.
Note:
ASM: Induction motor (induction motor)
PMSM: permanent-magnet synchronous motor
For bit 00:
This bit is equivalent to p1780 bit 1.
For bit 01:
This bit should only be set when required for large drives.
