Examples of the evaluation of the condition
The brake resistor cycle t
cyc,RB
= 150 s and the max. total braking
time t
brk,max
= 10 s are given. The braking times t
brk
and the
process cycle t
cyc,Prc
are exemplary.

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
).
