3-2-3 Dynamic brake characteristics
If a servo alarm that cannot control the motor occurs, the dynamic brakes will function to stop the
servomotor 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.
