Dynamic braking
Note:
⚫ If P4.30 is set to 1, the dynamic brake works when the motor speed is higher than the setting
(30 r/min by default) of P3.58 and it does not work otherwise. After the motor stops, the
dynamic brake does not work.
⚫ If the servo motor runs at a speed higher than the rated one, you cannot enable the dynamic
brake. If the servo motor runs at a high speed with a large inertia load, exercise caution
before using the dynamic brake. Do not restart the dynamic brake frequently. Otherwise, the
servo drive may be damaged.

This parameter specifies the maximum speed of the servo motor. If the absolute value of the speed
command is greater than the setting of this parameter, the actually-set speed is limited by this
parameter, and the actual direction is the same as that in the original speed command. This
parameter is valid in all modes.
Note: The default value and setting range of this parameter are associated with the drive power
class.

This parameter specifies the overspeed level for the servo motor. When the motor runs at a speed
higher than the setting of this parameter, an overspeed fault alarm is reported. If P4.32 is set to 0,
it indicates that overspeed fault alarm is disabled.
Note: The default value and setting range of this parameter are associated with the drive power
class.
