IRQ on MSC2250

IRQ on MSC2250 was created by softelectro
Hello everyone,

I've got an MDC2250 motor controller that i control with the C++ API. Sometime, the motor controller goes into error and i would like to know the error with the fault flag.

To avoid to ask again and again the motor controller, is it a way to have an IRQ when an error occurs?

Thanks in advance,

You can write a microbasic script that will monitor the status flags of the controller.

Refer to page 180 and 181 of the user manual.

Thanks for your reply,

I've made the small script but fault flag is always nul, so IRQ (D0) never change the level.

I think that the error that stop the motor is not due to overcurrent, over temperature, ... (= Fault flag error)
I think that the error come when the loopback error is to hight. Because when i disable or change the "CLERD" value, i can't recreate the error.

Like the loopback error security is active in specifique condition. Is there a simple solution to detect this error and make an IRQ?

Thanks in advance

You may have the October version firmware that had some bugs in it. Try updating with this one.

Hello,

The firmware int the motor controller was v1.2 05/25/2013, that I have update with the latest.

But I don't see the difference that I can use?

Thanks

There was a fault flag bug in the previous releases that has been fixed in the one I uploaded in this thread.

Outside of that, there is no harm in updating to the latest version.

Ok for the bug fixe, but I'm sure that the motor stop due to loopback error in tricky situation.

In the new firmware, is the loopback error report in the fault flag?
If so, which is the value return by the fault flag?
If not, how can I detect the loopback error security in a microbasic script?

Thanks

I've got an very old version of the user manual that don't have all new fonction.

So I will change the microbasic script to use _FM fonction.

And i make a big update.

Thanks for patient and your time
