R
min
= minimum allowed brake resistor that can be connected to the brake chopper
R
max
= maximum allowed brake resistor that allows R
max
P
BRmax
= maximum braking capacity of the drive, must exceed the desired braking power.
WARNING! Never 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.
