Product Role & Function
The 1336F-BRF75-AA-EN braking resistor is specifically designed for Allen-Bradley 1336F series drives. It assists in controlling excess energy generated during motor deceleration by converting it into heat, thereby helping the drive maintain stability during rapid deceleration or reverse operation.
Brake resistors are critical in applications involving frequent or abrupt deceleration, high-inertia loads, or extended braking time requirements.

Model-Specific FAQ
Common Problem
What is the function of this resistor in the drive system?
It dissipates regenerative energy generated by the motor during deceleration, preventing overvoltage on the drive's DC bus.
Why were 75 ohms and 75 watts selected?
These parameters match the braking requirements of a typical 1336F drive configuration, suitable for moderate braking energy.
Can the braking resistor be installed inside the same enclosure as the drive?
Only if the enclosure provides adequate ventilation and meets the temperature limits for both the resistor and the drive.
How does this resistor differ from a general-purpose resistor?
This product is specifically designed to match the regenerative characteristics and thermal management requirements of the 1336F series.
