The braking resistor is defined according to the deceleration time, load inertia
and resistive torque. In most cases a resistor with an ohmic value indicated on
table 8.12 and a power rating of 20 % of the driven motor can be used.
Use Wire type resistors with suitable insulation to withstand the instantaneous
current peaks.
For critical applications with very short braking times, high inertia loads (Ex:
centrifuges) or with very short and frequent duty cycles, contact WEG, to define
the most suitable resistor.
