Mitsubishi Electric MELDAS MDS-B-SVJ2 Series - Dynamic Brake Characteristics; Deceleration Torque

9-4 Dynamic brake characteristics
When an emergency stop occurs such as that due to a servo alarm detection, the motor will stop with
the deceleration control at the standard setting. However, by setting the servo parameter (SV017:
SPEC), the dynamic brake stop can be selected. If a servo alarm that cannot control the motor occurs,
the dynamic brakes stop the servomotor regardless of the parameter setting.
9-4-1 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.
