5 Communication Objects Description

In this section each of the objects mentioned in the Table 4.6 is fully described, besides also describing the
operation of the communication objects (COBs) mentioned in section 1.7. It is necessary to know how these objects
are operated in order to be able to use the available functions for the CFW-11 communication.

5.1 Identification Objects

There is a set of objects in the dictionary which are used for equipment identification; however, they do not have
influence on their behavior in the CANopen network.
5.1.1 1000h Object –
This object gives a 32-bit code that describes the type of object and its functionality.
This code can be divided into two parts: 16 low-order bits describing the type of profile that the device uses, and 16
high-order bits indicating a specific function according to the specified profile. For the CFW-11 these values are
respectively 0192h (it follows the specified by the
and 0001h (it has frequency inverter functionalities).
5.1.2 1001h Object –
This object indicates whether or not an error in the device occurred. The type of error registered for the CFW-11
follows what is described in the Table 5.1.
If the device presents any error, the equivalent bit must be activated. The first bit (generic error) must be activated
with any error condition.
