4-2 Dynamic brake characteristics
When an emergency stop occurs, the servo amplifier stops the motor with the dynamic brakes.
(Deceleration control stop can also be selected.) The dynamic brake characteristics are determined by
the servomotor and servo amplifier combination.
4-2-1 Deceleration torque
The dynamic brakes use the motor as a generator, and obtains the deceleration torque by consuming
that energy with the dynamic brake resistance. The characteristics of this deceleration torque have a
maximum deceleration torque (Tdp) regarding the motor speed as shown in the following drawing. The
torque for each motor is shown in the following table.
