Description
Braking power of the braking resistor (factory setting: 0 kW)
Set the braking power of the braking resistor.
Example: In your particular application, the motor brakes every 10 seconds. In so doing,
the braking resistor must handle a braking power of 1 kW for 2 s. Use a braking resistor
with a continuous rating of 1 kW × 2 s / 10 s = 0.2 kW, and set the maximum braking
power to: p0219 = 1 (kW).
Under certain circumstances, for low braking power ratings, the inverter extends the
ramp-down time of the motor.
For p0219 > 0, the inverter deactivates the VDC_max controller.
No coast down/coast down (OFF2) signal source 1
p0844 = 722.x
Monitor the overtemperature of the braking resistor with digital input x
