11.3 CANopen operation modes

This section describes the modes of operation specified by CiA DS402 when the servo is in the
CANopen mode. The content includes basic operation settings and related object descriptions.

11.3.1 Profile Position mode

After receiving the position command transmitted from the controller, the servo drive controls the
servo motor to reach the target position. In Profile Position (PP) mode, the controller only
informs the servo drive of the target position, speed command, and acceleration / deceleration
settings at the beginning. The motion planning from command triggering to the arrival of the
target position is performed by the trajectory generator in the servo drive.
The following figure shows the Profile Position mode architecture of the servo drive:
