Either for Safety reasons or for your process, sometimes you need to stop your motor or load extremely fast, faster than your drive is capable of doing.
When you need a solution, you can install a Dynamic Breaking Resistor with your Allen Bradley PowerFlex Drives to make it happen.
One of the coolest applications for safety is how we have helped amusement parks apply dynamic breaking to their rollercoasters.
