What is Slow or Fast Decay Mode in DC Motors

Does anyone can explain to me what is slow or fast decay mode in DC Motor and how I can do it using my Arduino setup? Thanks

Electronics i used:

  • BTS7960 High power motor driver
  • Arduino Nano
  • 550 Brushed Motor
  • RadioControl Transmitter and Receiver from a RC Car

That means acceleration or deceleration. How can we know anything about your Arduino setup?

Can you explain it further? Is it something that i can modify with my code to done that?

Sure, YOU can. We can't, you do know we can't see into your house?

Who can tell? How does your code make the motor go now? Is it from 0 to infinity in no time at all or does it go from to to some value over a time period you set?

Its goes from 0 to 255 base on your throttle input on your Radio Transmitter same goes with Reverse

The you will have to time delay the 0 to 255. Possibly 0 to 5 incremented by 1 every 100ms. Then 6-15, incremented every 50ms, then 16 to 200 every 10ms, then just 255.
Do the reverse when slowing down. Play with the both the time values and the steps.

Have you tried Google? The first result I got was:

It says basically the same thing I told you in your other post on the same subject:

Slow Decay = coasting
Fast Decay = braking

For posterity:
I think you made a minor mistake here.

Slow Decay = braking
Fast Decay = coasting

It's counterintuitive for sure, but remember the "decay" isn't talking about the motor speed, it's talking about the current flow.
