Cyclic Synchronous Position Mode - Omron R88L-EC Series User Manual

6 Basic Control Functions

Cyclic Synchronous Position Mode

In this mode of operation, the controller has a path generation function (an operation profile calculation
function) and it gives the target position to the Servo Drive using cyclic synchronization. Position
control, speed control, and force control are performed by the Servo Drive.
The Velocity offset (60B1 hex) and Torque offset (60B2 hex) can be used as speed feed-forward and
force feed-forward amounts.
Precautions for Correct Use Precautions for Correct Use
According to the CiA 402 Drive Profile, the object names between 6000 hex and 6999 hex may
be represented using the word "torque," instead of force. Read it as "force" when using this
function.
