Sensorless Vector Control (SVC) Recommended Dynamic Brake
Modules for Option DB1 (IP67 Resistor)
➊ Drive rating and DB part numbers are not interchangeable. Only use specified resistor. Customer is responsible to evaluate if
performance meets application requirement.
Note: Duty Cycle listed is based on full speed to zero speed deceleration. For
constant regen at full speed, duty cycle capability is half of what is listed.
Application Type 1 represents maximum capability up to 100% braking torque
where possible.
