Note
Ɣ
Minimum resistance supports operating condition with ED of 10% and longest time for single
braking of 10s.
Ɣ
Default initial braking voltage is 760 V.
Ɣ
The preceding table is for a 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 generation 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.
