P Maximum braking power of the drive with the specified resistor(s). The drive and the chopper will withstand this
br5
braking power for 5 seconds per minute.
P The drive and the chopper will withstand this braking power for 10 seconds per minute.
br10
P The drive and the chopper will withstand this braking power for 30 seconds per minute.
br30
P The drive and the chopper will withstand this continuous braking power. The braking is considered continuous if the
brcon
braking time exceeds 30 s.
t
Note: Check that the braking energy transmitted to the specified resistor(s) in 400 seconds does not exceed E
R Resistance value for the 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
R
element from 40 °C (104 °F) to the maximum allowable temperature.
P Continuous power (heat) dissipation of the resistor when placed correctly. Energy E
