Hi team,

My customer wants to stop the DC motor as soon as possible.

1. Which Decay mode is faster to stop the DC Motor?

2. If First Decay is faster than Slow Decay, what has concern to use First Decay for stopping DC motor?

Hi Ogasawara-san,

1. Slow decay will stop the motor the fastest. We also call this "brake" in the datasheet.

2. We call fast decay "coast" in the datasheets. With fast decay, the motor will stop under its own friction.
