P
Maximum braking power of the drive with the specified resistor(s). The drive and the chopper
br5
withstand this braking power for 5 seconds per minute.
P
The drive and the chopper withstand this braking power for 10 seconds per minute.
br10
P
The drive and the chopper withstand this braking power for 30 seconds per minute.
br30
P
The drive and the chopper withstand this continuous braking power. The braking is
brcont
considered continuous if the braking time exceeds 30 s.
Note: Make sure that the braking energy transmitted to the specified resistor(s) in 400 seconds does
E
not exceed .
R
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
R
heats the 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
dissipates in 400 seconds.
