• Pr: the power of resistor.
• D: the braking frequency (percentage of the regenerative process to the whole working process)

Selection of the
Breaking Frequency
The following table provides data for reference. User may select different resistance and power based on their
actual needs. However, the value of resistance must not be greater than the recommended value. The power
may be larger than the recommended value.
The braking resistor model depends on the generation power of the motor in the actual system and is also
related to the system's inertia, deceleration time and potential energy load. The higher a system's inertia is,
the shorter the deceleration time is. Frequent braking requires braking resisters of larger power and smaller
resistance.
