3 Characteristics

3.1.2 Dynamic Brake Characteristics

If a servo alarm that cannot control the motor occurs, the dynamic brakes will function to stop the direct-drive motor regardless
of the parameter settings.
(1) Deceleration torque
The dynamic brake uses 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.
