Constant Cycle Time Function Enabled for Coordinator Module

When in Sync Mode with a Sync Cycle Time set for the Coordinator Module cycle time (default), and the constant cycle time function is used, the cycle time for Motion Control Modules will be as described below.

The Motion Control Module cycle time is synchronized with the Coordinator Module constant cycle time, and will therefore be constant.

Constant Cycle Time Function Enabled for Motion Control Module

The Motion Control Module cycle time is synchronized with the Coordinator Module constant cycle time, and gradually is made constant, while the Motion Control Module's built-in I/O refresh timing is made constant.

The time from when the processing starts in the Motion Control Module until the I/O refresh will be constant.
