Transferring Data
Section 5-1
5-1 Transferring Data
The following two types of data can be transferred by the Position Control Unit
(PCU).
1,2,3... 1. PCU Parameters
• Common Parameters
• Axis Parameters
2. Servo Drive Parameters
• Servo Parameters
There are two ways to transfer these parameters.
• Using the Support Software to transfer parameters to and from a Win-
dows computer connected to the CPU Unit
• Using the bits in the Operating Memory Areas allocated to the PCU in the
CPU Unit to transfer parameters to and from I/O Memory in the CPU Unit
Transferring Parameters
Using Support Software The CX-Motion-NCF Support Software can be used on a Windows computer
to set and transfer parameters for the PCU, to save and print the parameters,
and to monitor PCU status.
Refer to the CX-Motion-NCF Operation Manual (Cat. No. W436) for operating
procedures and other information on the CX-Motion-NCF.
Transferring Parameters
Using Bits in Operating
Memory Areas Bits in the Operating Memory Areas can be manipulated to transfer data
between the CPU Unit and the PCU (and Servo Drives). The Common Oper-
ating Memory Area is used for parameters held in the PCU and the Axis Oper-
ating Memory Areas are used for parameters held in the Servo Drives.
Transferring PCU
Parameters Common Parameters and Axis Parameters are saved in the PCU's internal
memory and also in the PCU's flash memory. These parameters are read/
written, or saved to flash memory from the CPU Unit using the WRITE DATA,
READ DATA, and SAVE DATA Bits allocated in the Common Operating Mem-
ory Area.
The number of transfer words, transfer source, and transfer destination are
specified in the Common Operating Memory Area. It is possible to transfer
multiple parameters at once.
For PCU parameters, the parameters stored in memory are saved altogether
to the PCU's internal flash memory.
