5.1.8 Types and roles of control data 

Several controls are carried out as necessary when using the positioning system. 
(When the power is turned ON, the default values of the data used for control are set. 
However, these values can be set with the sequence program when necessary.) 
The items that can be controlled are shown below. 

 



 Controlling the system data 

 

Sets the clock data in the D75P2, and reads/writes the "positioning data". (System 
control data 

Cd.1  to  Cd.10 ) 

 



 Controlling the operation 

 

Makes settings related to the operation, and controls the speed change during 
operation, and stops/restarts the operation. (Axis control data  Cd.11  to
