In the above example, the dimensioning condition is observed at all times. In the example
below, the dimensioning condition is once not observed, which means that the brake
resistor selected is not suitable for the process specified. Use a brake resistor with a greater
power (shorter brake resistor cycle t

cyc,RB

).
