Configure manipulated value TCONT_S
Pulse generator
1. Enter the minimum impulse duration and minimum pause duration.
The values must be greater than or equal to the cycle time for the input parameter
CYCLE. The frequency of operation is reduced through this.
2. Enter the motor setting time.
The value must be greater than or equal to the cycle time of the input parameter CYCLE.

Requirements
● The instruction and the technology object have been loaded to the CPU.
To manually determine the optimal PID parameters, proceed as follows:
1. Click the "Start" icon.
If there is no online connection, this will be established. The current values for the
setpoint, process value and output value are recorded.
2. Enter new PID parameters in the "P", "I" and weighting proportional action fields.
3. Click on the icon
"Send parameter to CPU" in the "Tuning" group.
4. Select the "Change setpoint" check box in the "Current values" group.
5. Enter a new setpoint and click in the "Current Values" group on the icon
.
6. Clear the "Manual mode" check box.
The controller works with the new parameters and controls the new setpoint.
7. Check the quality of the PID parameter to check the curve points.
8. Repeat steps 2 to 6 until you are satisfied with the controller results.
