How to adjust the parameters of the tension controller

Hello may I ask you what brand of tension controller what type it is
Now the general industry equipment is mainly used Mitsubishi Mengte Fu KORTIS and other tension control system. Force divided by model type floating roller and so on.
In short the general tension controller requires only two basic installation and operation can be fine-tuning of other parameters depends on the specific needs of the specific function.
Installation procedure is very simple step by step according to the instructions on the can in general is clear calibration depends on different models.
Fine-tuning is based on a PID tension control system setting function
For a controller PID settings generally perform the following adjustments: General D first derivative value of zero the integral I set a small number between 5-10 to change the P value from small to large until the system can adjust stability when the P After adjustment plus an outside interference to see the system back to balance the time needed if slow increase the I value until a satisfactory result the general system changes through two cycles of equilibrium for the best.
The tension controller is to control the basic function of course tension constant tension system for example to
The actual value and set value of tension compared to control output size.
For example the tension setting is 5N when the actual value is greater than 5N the output value is smaller / larger (depending on the phase setting) infinitely close to 100% / 0 (depending on the phase setting) to control the brake torque or the drive frequency.
