Resistor braking
123
P
br5
Maximum braking power of the drive with the specified resistor(s). The drive and the chopper will withstand this braking power for
5 seconds per minute.
P
br10
The drive and the chopper will withstand this braking power for 10 seconds per minute.
P
br30
The drive and the chopper will withstand this braking power for 30 seconds per minute.
P
brcont
The drive and the chopper will withstand this continuous braking power. The braking is considered continuous if the braking time
exceeds 30 s.
Note: Check that the braking energy transmitted to the specified resistor(s) in 400 seconds does not exceed
E
R
.
R
Resistance value for the resistor assembly.
Note:
This is also the minimum allowed resistance for the brake resistor.
E
R
Short energy pulse that the resistor assembly withstands every 400 seconds. This energy will heat the resistor element from
40 °C (104 °F) to the maximum allowable temperature.
P
Rcont
Continuous power (heat) dissipation of the resistor when placed correctly. Energy
E
R
dissipates in 400 seconds.
