Vendor-Specific (Yaskawa) Class Objects

Yaskawa Drive Parameters Object - 100 (Class 0x64)
Services Supported
Service Code No. (hex)
This is a dynamic explicit Class Object. With this Class object any drive parameter with a MEMOBUS/Modbus address
greater than 0x00FF can be accessed. The mapping of Class Object instance / attribute to MEMOBUS/Modbus address is
as follows.
Given a typical MEMOBUS/Modbus Address of 0xXXYY
The DeviceNet Instance value is equal to XX
The DeviceNet Attribute value is equal to YY
As an example, to access parameter b5-12 (MEMOBUS/Modbus Address =0x01B0)
Class Object is 100 (0x64) (Always for this Class Object)
Instance = 0x01
Attribute = 0xB0
Note: Writing a zero to 0x0900 (Enter) stores changed parameters to the drive non-volatile memory. Writing a zero to 0x0910 (Accept)
allows the drive to use the changed parameters. This normally is automatically sent when the parameter is changed. Read Enter
Command 0x0900 or Accept Command 910 will always return a value of 0x0001.

Note: Attempting to set a read-only parameter results in a DeviceNet error code of 0x0E, Attribute Not Settable.
Note: Attempting to access an invalid parameter results in a DeviceNet error code of 0x09, Invalid Attribute Value
Note: Refer to the MEMOBUS/Modbus Data Table in Appendix C of the technical Manual for the drive the DeviceNet Option is
connected to for a list of monitor data using the MEMOBUS/Modbus message area.
