Yaskawa DeviceNet Option Card CM05x - Manual (Page 38)

Configuration of Drive DeviceNet Parameters 6-3
The Polled Consuming Assembly (PCA) parameter determines the format of the data that is transmitted from the
Master device to the Drive. The PCA data is transmitted from the Master device to a Drive with a Poll Command
message. The PCA data is used to control the operation of the Drive. One of the assemblies from the following
table must be selected. See Appendix B for details of the assemblies.
