TMDXIDDK379D: C2000 DesignDRIVE IDDK Kit issues
Part Number: TMDXIDDK379D
I am using DesignDRIVE IDDK kit to develop motor control system, all system work properly the problem is only Accelration and Deceleration, How can I set required Acceleration and Deceleration, I can set maximum Accel. By setting the speed PI loop saturation value but I want to know how can I set desired Acceleration and Deceleration according to system application like Variable frequancy derive.
When you feed speed command into the speed loop, generate the speed command by passing it through the preprogrammed accel and decal rates. You should not be depending on the speed loop saturation value because in that case, accel / decel is decided by the load inertia and load torque. Hope it helps.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Ramesh Ramamoorthy:
Thanks for your speedy reply,
Sir my question is how can I change Accelration and deceleration of my motor in IDDK kit software,
Our end customer demand is changing Acceleration and Deceleration according to their need, we need your help how can we develop a piece of software for our customers so they can change Acceleration and Deceleration of Delfino dual core mcu based motor control inverter according to their need.
For your reference "We developing inverter for our customer it will use for CNC"
In reply to Asim Gulzar22:
I think that is what I tried to answer. Acceln and deceln rates are outside the scope of the servo loop and the user is supposed to take care of this in their application. We don't have a standard module.
If you can write a code to increment/ decrement the speed command by a certain value after every ISR, it will decide the accel/decel rate. Hope you get this point.
Ok sir, Can you tell me where I can found preprogramed Acel /deceleration value in iddk software code , as you mention in your first reply
What we have is a crude way of doing, review the module RC_MACRO and its parameters. It is given in our example.
If this is not good enough, you have to write your own or improvise on your own.
Pls close the thread if the issue is resolved
Due to long silence, we assume the issue is resolved and are closing the thread.
