Proceed as follows to monitor the braking resistor temperature:
1. Connect the temperature monitoring system of the braking resistor (terminals T1 and T2
on the braking resistor) to a free digital input on the inverter.
Image 4-16 Example: Temperature monitoring of the braking resistor via digital input DI 3 on the
Control Unit
2. Define the function of the digital input used as an external fault with p2106.
As an example with temperature monitoring via digital input DI 3: p2106 = 722.3.
You have ensured that the temperature is monitored.
