Yes, there are a couple ways. An ErrorID of 4625 (invalid axis) will be output if a PLCopen function block is executed with an AXIS_REF axis which is not defined or not present on a system. The example in the attached pdf shows logic to indicate that an axis is not present on the system.
Another method, available in firmware version 2.0 and higher, is to read parameter 1330, which indicates the Mechatrolink communication status of the specified axis.
