Furthermore, for UI modules, it must be observed that the braking energy does
not exceed the pulsed resistor rating:
S 5 kW infeed module
– 200 W continuous output
– 10 kW short–time output
for 120 ms once per 10 s switching cycle without pre–load condition
S Infeed module 10 kW
– 300 W continuous output
– 25 kW short–time output
for 120 ms once per 10 s switching cycle without pre–load condition
S Infeed module 28 kW
– max. 2 x 300 W continuous output
– max. 2 x 25 kW short–time output
for 120 ms once per 10 s switching cycle without pre–load condition
or
– max. 2 x 1.5 kW continuous output
– max. 2 x 25 kW short–time output
for 120 ms once per 10 s switching cycle without pre–load condition
For 28 kW UI, the pulsed resistors must be separately ordered and must be
externally mounted.
For higher regenerative feedback powers, a separate pulsed resistor module
must be used or the regenerative feedback power must be reduced by using
longer braking times.
