R = Resistance of specified resistors (per chopper). This is also the minimum allowed resistance of the resistor assembly.
P = Maximum short-term (1 min every 10 mins) braking power
brmax
P = Maximum continuous braking power
brcont
I = Maximum peak current
max
P = Braking power for the specified duty cycle
