DB Resistor Kits
VS1MD drives include built-in braking transistors to aid in applications requiring the ability to stop rapidly. External braking
resistors are required to implement the dynamic braking function. The below resistor selection provides resistors that are
designed for 15% to 20% duty cycle braking applications. These resistors must be separately mounted.
