Dynamic braking

Summit servo drives include a feature known as “Dynamic braking”, which is a method used for braking electrical motors. This process involves transforming mechanical energy into heat or electrical energy to decelerate and halt movement.

When dynamic braking is enabled, all PWM phases are shorted to GND when the power stage is disabled.

The motor shaft will be blocked when the power stage is disabled and Dynamic braking is enabled.

Dynamic braking can be configured using 0x262E - Dynamic brake option code

Disabling the power stage while dynamic braking is enabled and the motor is in motion may result in a destructive operation due to the high current values induced to the transistors.

The graphs below illustrate the braking times of the motor with and without dynamic braking.
