increment plus the current position. This command is useful when trying to synchronize the position
of two motors while they are moving.
Note that the controller operates as a closed-loop position controller while in the jog mode. The CDS-
3310 converts the velocity profile into a position trajectory and a new position target is generated every
other sample period. This method of control results in precise speed regulation with phase lock
accuracy.
