MEMOBUS I/O Instances
All of the Inverter’s constants can be referenced and set with a
MEMOBUS I/O instance.
MEMOBUS I/O instances can be used with Yaskawa Inverters only.
They cannot be used with other companies’ DeviceNet-compatible
Inverters.
Five bytes are used for input data and five bytes are used for output
data.
Always execute the ENTER command when changing constants. See
ENTER Command (Write-only Register) on page 126 for details.
