4-1-9 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.
