5.6.3 Profile Velocity Mode (PV)
In asynchronous motion mode, master device is only responsible for sending motion
parameters and control commands.EL7-EC servo drive will conduct trajectory planning
according to the motion parameters sent by master device after receiving the motion
start command from the master device. In asynchronous motion mode, the motion
between each axes is asynchronous.
PV Block Diagram
The difference between PV and CSV mode is that PV needs EL7-EC to have the function
of trajectory generator. The input and output structure of the trajectory generator is
shown in figure 7.8
