Table 8-16 provides data for reference. You can select different resistance and power based
on actual needs. However, the resistance must not be lower than the recommended value.
The power may be higher than the recommended value.
The braking resistor model is dependent on the generation power of the motor in the actual
system and is also related to the system inertia, deceleration time and potential energy
load. For systems with high inertia, and/or rapid deceleration times, or frequent braking
sequences, the braking resistor with higher power and lower resistance value should be
selected.
