Yaskawa URS000257
A1000 - Dynamic Braking
Rated for 10% duty cycle over a 100-second interval. Approximate braking torque for each rating is listed. These resistors are designed in vented NEMA 1 enclosures for sparate panel mounting. The built-in braking module supports the 3% and 10% duty cycle resistors listed here and also 50% and 100% duty cycle resistors. For duty cycles above 10% please contact Yaskawa.
