R Resistance value for the listed resistor assembly. Note: This is also the minimum allowed resistance for the brake resistor.
E Short energy pulse that the resistor assembly withstands every 400 seconds. This energy will heat the resistor element from 40 °C
R
(104 °F) to the maximum allowable temperature.
P Continuous power (heat) dissipation of the resistor when placed correctly. Energy E
Rcont
P Maximum braking power of the drive equipped with the standard chopper and resistor. The drive and the chopper will withstand this
brmax
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
All braking choppers and resistors must be installed outside the converter module. Note: The SACE and SAFUR resistors are not UL
listed.
