Since the brake of the servo motor is designed for position holding, it must be enabled at the right time
when the motor stops. While observing the action of the machine, adjust the user parameters.
5.2.6 Braking setting
When the servo motor is driven by the generator mode, the power returns to the servo amplifier
side, which is called regenerative power. Regenerative power is absorbed by charging the smoothing
capacitor in the servo amplifier. After exceeding the rechargeable energy, the regenerative resistance is
used to consume the regenerative power.
The servo motor is driven by regeneration (generator) mode as follows:
Deceleration stop period during acceleration and deceleration operation;
When the vertical axis is running downward;
When the external load drives the motor to rotate.
