R Resistance value for the listed resistor type. Note: This is also the minimum allowed resistance value for the braking
resistor.
E
R
Energy pulse that the resistor assembly will withstand (400 s duty cycle). This energy will heat the resistor element
from 40 °C to the maximum allowable temperature.
P
Rcont
Continuous power (heat) dissipation of the resistor when placed correctly. Energy E
R
dissipates in 400 seconds.
A Conductor cross-sectional areas for the copper cable to be used for connecting the braking resistor and the chopper
(or the chopper and the ACS 600). The cable should have a concentric conductor (screen). The standard cables with
three-phase conductors and a concentric conductor are given. A two-conductor screened cable may also be used if
available.
P
BRmax
Maximum braking power of the ACS 600 equipped with the standard chopper and the standard resistor. The drive and
the chopper will withstand this braking power for one minute every ten minutes.
Note: The braking energy transmitted
to the resistor during any period shorter than 400 seconds may not exceed E

* The SACE04RE40 resistor consists of four resistor elements connected in parallel. The resistance of one element is 160 ohm.
The SACE15RE13 resistor consists of four resistor elements connected in parallel. The resistance of one element is 52 ohm.
The SACE15RE22 resistor consists of four resistor elements connected in parallel. The resistance of one element is 88 ohm.
The SAFUR resistors consist of several resistor elements. The resistance of one element is 8 ohm
.
The NBRA-653 and -663 are to be installed outside the converter module. Their degree of protection is IP54.
The NBRA-654, -655, -656, -657, -664, -666 and -667 are to be installed inside the converter module.
The NBRA-658, -659 and -669 are to be installed outside the converter module. Their degree of protection is IP00.
All braking resistors are to be installed outside the converter module.
The SACE braking resistors are built in an IP21 metal housing.
The SAFUR braking resistors are built in an IP00 metal frame.
