After completing the reading of the input signal, the PFCL201CE-50KN needs to digitally filter the tension sampled signal, compare it with the tension value set by the user, and control the output PWM wave through PID adjustment. The length of the material can be calculated by combining the time collected by Timer 2 with parameters such as the roller diameter and material thickness set by the user. When the receiving reel receives a user’s request, if the full material alarm is activated, it can remind the user to replace the reel; Similarly, the low material alarm can be activated during unwinding. When the measured PFCL201CE-50KN digital quantity is very small, if the zero tension alarm is enabled, it can remind the user of abnormal operation.

When the program is running, we can create a storage space in FLASH to save the user set parameters here. Every time we start up, we can first read the parameters from this storage space, so that the system can not only run accurately, but also reduce a lot of setup hassle. However, during the operation of the system, there may also be a sudden power outage. At this time, it is necessary to save the diameter of the roll (the diameter of the unwinding or unwinding roll), and the roll diameter does not need to be calculated from the initial value when starting up the next time. The PFCL201CE-50KN is equipped with a programmable voltage monitor, where the voltage monitoring interrupt function can be enabled, so that the current roll diameter can be stored using the on-chip blank FLASH in the moment of power failure. Table 1 shows some parameters that users need to set during the tension control process.
