6-4 Cyclic Synchronous Velocity Mode
In this mode of operation, the controller has a path generation function (an operation profile calculation
function) and it gives the target velocity to the Servo Drive in cyclic synchronization.
The Torque offset (60B2 hex) can be used as the torque feed-forward amount.
The following diagram shows the configuration of the Cyclic synchronous velocity mode.
