PTC braking resistors
Observe the following points for PTC braking resistors:
- Only recommended for applications with little regenerative energy.
- The resistor reversibly protects itself against overload by changing abruptly to high resistance and no longer consuming any more energy.
- The inverter then switches off and signals a "brake chopper" fault (fault F04).
