Notes: Minimum resistance supports operating condition with D of 10% and longest time for single
braking of 10s.
Default initial braking voltage for built-in brake units (IGBT) is 760 V.
The preceding table is for reference only. You can select resistance and power of braking resistor
based on actual needs. Resistance must not be lower than the reference value. Power may be higher
than the reference value. Selection of braking resistor model is determined by horse-power of motor
and is also related to system inertia, deceleration time and potential energy load. For systems with
high inertia, and/or short deceleration time, and/or frequent braking, select a braking resistor with
higher power and lower resistance value.
