Brief description
The position controller of the positioning axis/synchronous axis is a closed-loop P controller
with pre-control of velocity.
If the drive supports Dynamic Servo Control (DSC), then a closed-loop position controller in
the drive can optionally be used.
Dynamic Servo Control (DSC)
In drives that support Dynamic Servo Control (DSC), you can optionally use the closed-loop
position controller in the drive. The position controller in the drive is usually implemented with
a rapid speed-control cycle. This improves the control performance for digitally coupled
drives. The communication times between controller and drive are automatically taken into
account.
For DSC, the drive's encoder must be used and standard message frame 5 must be set on
the drive.
