W
iring and Settings for the Dynamic Brake
If it is not necessary to reduce the brake torque, select a Dynamic Brake Resistor with the fol-
lowing resistance.
If it is necessary to reduce the brake torque, determine the resistance based on the character-
istic graphs.
The following graphs show the relationship between the instantaneous maximum brake torque
of the Servomotor and the resistance of the dynamic brake.
