Will Lexium 32 support 3rd party motors that use AB digital type encoders?

No, Lexium 32 will only support 3rd party motors that use resolver, HIFA analog type encoders or SinCos type.
Digital encoder such a AB type will not function with Lexium 32 for 3rd party motor commutation.

For overview of supported encoder types see image file.
