9. INTERFACE MODE 

 
9.7 Command data update cycle 

The update cycle of command can be changed by command data update cycle of Interface mode option 
(parameter No.000F). Have the user program generate the command for every command data update cycle, 
and set to command buffer. 

 

Note. Because communication with the servo amplifier is performed every control cycle, the current feedback position and other high 

speed monitors are updated every control cycle.
