Configuration - Control loop

In the "Control loop" configuration window, configure the gain Kv of the position control loop.
The Kv factor affects the following parameters:
● Positioning accuracy and stop control
● Uniformity of motion
● Positioning time
The better the mechanical conditions of the axis are (high stiffness), the higher the Kv factor
can be configured. This reduces the following error, and a higher dynamic response is
achieved.
For basic information, refer to the section Control (Page 59).
Precontrol
In this box, configure the percentage velocity precontrol of the position control loop.
Gain
In the input field, enter the gain Kv of the control loop.
Dynamic Servo Control (DSC):
For position-controlled axes (positioning axes/synchronous axes), the position control can
occur either in the CPU or in the drive, provided the drive supports the Dynamic Servo
Control (DSC) control process. Select your preferred control process:
● Position control in drive (DSC enabled)
● Position control in the PLC
Note
Dynamic Servo Control (DSC) is only possible with standard frame 5.
