Symbols
R min = minimum allowed brake resistor that can be connected to the brake chopper
R max = maximum allowed brake resistor that allows P BRmax
P BRmax = maximum braking capacity of the drive, must exceed the desired braking power.
WARNING!
Do not use a brake resistor with a resistance below the minimum value specified
for the particular drive. The drive and the internal chopper are not able to handle
the overcurrent caused by the low resistance.
