DeviceNet Profiles 8-3
AC Drive Profile
The AC Drive Profile uses assemblies to transfer I/O data. The AC Drive Profile defines the following list of
Assemblies:
Assembly
Required or
Optional
I/O Type✹ Name
20 Required Basic Speed Command
21 Optional Extended Speed Command
22 Optional Basic Speed and Torque Command
23 Optional Extended Speed and Torque Command
24 Optional Basic Process Control Command
25 Optional
Output
(Output from the
Master/PLC)
Extended Process Control Command
70 Required Basic Speed Status
71 Optional Extended Speed Status
72 Optional Basic Speed and Torque Status
73 Optional Extended Speed and Torque Status
74 Optional Basic Process Control Status
75 Optional
Input
(Input to the
Master/PLC)
Extended Process Control Status
The data format of each of the assemblies listed above is defined in the AC Drive Profile. The drive behavior
relevant to each of the assemblies is defined in the AC Drive Profile. Notice that some of the assemblies are
required and some are optional.
The AC Drive Profile dictates that an AC Drive device must support the following DeviceNet Object Classes:
• Motor Class
This class defines motor data for the motor that is connected to the drive.
Instance 1, Attributes 3, 6, and 7 are required. All other attributes are optional.
• Control Supervisor Class
This class manages drive functions, operational states and control.
Instance 1, Attributes 3, 7, 10, and 12 are required. All other attributes are optional.
• AC Drive Class
This class provides access to drive configuration parameters.
Instance 1, Attributes 4, 6, 7, and 8 are required. All other attributes are optional.
If an application uses only the required assemblies and attributes from the AC Drive Profile, interchangeability
between devices, which comply with the AC Drive Profile is guaranteed.
The Yaskawa Drive DeviceNet Option Board conforms to the AC Drive Profile. A listing of the attributes of the
Motor Class, Control Supervisor Class, and AC Drive Class can be found in Appendix A. A listing of the
Common Services provided by each of these classes can be found in Appendix C. For a description of the
behavior elicited by each of these classes, please consult the DeviceNet Specification, Volume II.
