A braking resistor is used for the SINAMICS V70 drive. For the feed drive, when the internal braking resistor cannot meet the
braking requirements, an external braking resistor can be used to "dump" the regenerative energy produced by the motor,
thus giving greatly improved braking and deceleration capabilities. For the spindle drive, an external braking resistor must be
configured. Select a standard braking resistor according to the table below:
When selecting a braking resistor, you must take into account the factors such as braking inertia, deceleration time,
speed variation, and braking period according to your specific application and technology. The resistance of the selected
braking resistor must not be lower than the minimum resistance listed above.
To achieve EMC-compliant installation of the drive, use shielding plates to connect the cable shields. The shielding plate for
V70 spindle drive FSD is provided as an option. While for V70 drives of other frame sizes, the shielding plates are provided
at delivery.
