Notes:
(1) The effective braking current presented is just an indicative value, because it depends on the braking duty cycle. The effective braking current can be obtained from the equation below, where t
br
is given in minutes and corresponds to the sum of all braking times during the most severe cycle of 5 (five) minutes.
I
effective
= I
max
· t
br
5
√
(2) The P
max
and P
R
values (maximum and mean power of the braking resistor respectively) presented are valid for the recommended resistors and for the effective braking currents presented in the
table. The resistor power must be changed according to the braking duty cycle.
