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.
(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 table 3.3. The resistor
power shall be changed according to the braking duty cycle.
(3) For specifications on the recommended terminal type (screw and tightening torque) for the connection of
the braking resistor (terminals DC+ and BR), refer to the DC+ terminal specification at the table 3.2. There
are plastic covers in front of the DC-, DC+ and BR terminals at the frame size C. It is necessary to break
off those covers in order to get access to these terminals.
