Error codes

[can can canopen]

Hello everyone,

I am working with CANopen for last 4 to 5 months, the device which i am using is Motor controller drive,Communication used is CANopen.

When I was testing for Emcy with the help of CANopen library, I am getting confused.

The plasma dictionary which I have describes the error codes for ex 3120h,3211h,3212h,3221h etc under voltage error.

But when i read the same error code with the help of Emcy Wait and Emcy Convert , Generic error bit sets .

The voltage bit does not glow and i dont get any error description , why is this????

Are the above error codes user defined??

When I open the Emcy convert VI there are some codes in which the voltage error is defined,the above error codes wont come in that category is it.

Thanks in advance

Hi,

You wrote: " The voltage bit does not glow and i dont get any error description ", does that mean you expect the  Voltage Error Bit set?

What is the error register Byte and the manufacturer specific error field  array in your case?

The Emergency Convert Vi only knows the default errors . You can see them if you open the VI BD.

You could add your specific hex numbers thus you would get the correct message.
