Feedback Position Monitoring Function
With PCU of pulse-output type, the position control loop is at the driver side regardless of
whether the application is of semi-closed loop or full-closed loop method.
However, this PCU can input encoder feedback.
You can use either an incremental encoder or absolute encoder.
The functional purpose of the feedback position counter on the PCU side is to perform
operation checks against command positions.
Depending on the settings, you can also have the command present position and feedback
position reflected in both directions, and use the feedback position for position monitoring.
