Description
Braking power of the braking resistor (factory setting: 0 kW)
For p0219 > 0, the inverter deactivates the VDC_max controller.
For vector control, p0219 specifies the regenerative power limit p1531.
Set with p0219 the maximum braking power that the braking resistor must handle.
The inverter extends the ramp-down time of the motor when the braking power is too low.
You can find the technical data of the braking resistor in the Power Module hardware
installation manual.
Overview of the manuals (Page 519)
The SIZER PC tool provides support for calculating the braking power.
