I drive the motor to rotate a half-circle.
When the motor is running , I set the chopping current to 1.33A,
When the motor stops, I set the chopping current to 0.24A, and in most case, the supply current of 24V is about 0.13A when the motor stops.
But in some cases , the supply current of 24V is about 0.04A when the motor stops.and the motor can be rotated manually wiith few resistance.
what's the reason ?
Then I try the fast decay mode : when the motor stops.,the supply current of 24V is also about 0.04A and the motor can also be rotated manually wiith few resistance.
So I guess maybe the current decreased to 0 during chopping. Would the situation I decribed happen?
So, I plan to incease the chopping current when the motor stops, or I want to try to increase the value of C11. Here is my schematic:(some value is not the same as what I use to test.)
