For the UI module, it must also be observed that the braking energy, which is
fed in, does not exceed the power rating of the pulsed resistor:
S 5 kW infeed module
– 200 W continuous power
– 10 kW short–time power
for 120 ms, once per 10 s load duty cycle without pre–load condition
S 10 kW infeed module
– 300 W continuous power
– 25 kW short–time power
for 120 ms, once per 10 s load duty cycle without pre–load condition
Danger
During operation and shortly after shutdown, the surfaces exhibit temperatures
that may cause burn injuries and fires!
S 28 kW infeed module
– max. 2 x 300 W continuous power
– max. 2 x 25 kW short–time power
for 120 ms, once per 10 s load duty cycle without pre–load condition
or
– max. 2 x 1.5 kW continuous power
– max. 2 x 25 kW short–time power
for 120 ms, once per 10 s load duty cycle without pre–load condition
For the UI 28 kW, the pulsed resistors must be separately ordered and must be
externally mounted.
For higher regenerative feedback powers, a separate pulse resistor module
must be provided or the regenerative feedback power must be reduced by us-
ing longer braking times.
Operating drive modules with 1FT6, 1FK and 1FN motors with an unregu-
lated infeed
Owing to the lower DC link voltage of 490 V
1)
with UI modules (600 V for I/R
modules), the following restrictions may apply:
S Reduction of dynamic drive properties in the upper speed/velocity range
S Lower utilization of the rated motor speed/velocity if operation under over-
load conditions is still required.
1) For a line supply infeed with 3–ph. 400 V AC –10%.
