The address of the current position obtained with the machine coordinates is 
stored. (Different from the actual motor position during operation) 
The machine feed value is not changed by the current value change function. 
Updated during speed control regardless of the parameter setting. 
Not cleared to 0 when fixed-dimension feed is started. 
Does not change into the ring address of 0 to 359.99999  in the "degree" unit.

" Da.7  Command speed" of positioning data currently execution is stored. 
 When "–1" is set for " Da.7  Command speed": The command speed of the 
previous positioning data is stored. 
 When a value other than "–1" is set for " Da.7  Command speed": The 
command speed of the positioning data currently being executed is stored. 
 When the speed change function is executed : "New speed value (RWwm+4 to 
5, RWwm+12 to 13)" is stored. (For details of the speed change function, refer 
to Section 12.5.1.)
