COMMUNICATION OBJECTS DESCRIPTION
8 COMMUNICATION OBJECTS DESCRIPTION
This item describes in detail each of the communication objects available for the SSW900 soft-starter. It is necessary
to know how to operate these objects to be able to use the available functions for the SSW900 soft-starter
communication.
8.1 IDENTIFICATION OBJECT
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.
8.1.1 Object 1000h - Device Type
This object gives a 32-bit code that describes the type of object and its functionality.

high-order bits indicating a specific function according to the specified profile.
8.1.2 Object 1001h - Error Register
This object indicates whether or not an error in the device occurred. The type of error registered for the equipment
