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
R
resistor element from 40 °C (104 °F) to the maximum allowable temperature.
P Continuous power (heat) dissipation of the resistor when placed correctly. Energy
Rcont
seconds.
P
Maximum braking power of the drive equipped with the standard chopper and resistor. The drive and the
brmax
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
All braking choppers and resistors must be installed outside the drive module. Note: The SACE and SAFUR resistors
are not UL listed.
