PPD113B01-10-150000 3BHE023784R1023 the rotation process inserted into the pause phase, so that the speed control system to reduce the speed, thereby reducing the inertia of the system, the use of this control method, can be very good to eliminate the phenomenon of oscillation, the control accuracy has been greatly improved, but if the whole process of using this kind of stepping drive control method to regulate the regulation, the regulation time will also be However, if this stepper drive control method is used throughout the adjustment, the adjustment time will be much longer, which is absolutely not allowed in many occasions in the process of industrial use.

PPD113B01-10-150000 3BHE023784R1023 combines the advantages of the 1st and 2nd control schemes. When the absolute value of the difference between the actual valve position value Pv and the set value Sv is greater than En, the module adopts the long pulse drive; when the difference between the two is between the threshold value En and one-half of the dead zone DeadZoon with a short pulse step by step control, that is, the module outputs a short pulse of the Ton time and waits for the Toff time until the valve value and the set value of the difference between the absolute value of the difference between the two values is less than one-half of the dead zone.

PPD113B01-10-150000 3BHE023784R1023 output part of the internal non-movable parts, so it has a reliable, fast switching speed, high operating frequency, long life, no electromagnetic interference and other characteristics. Therefore, it is recommended that solid state relays be used for high frequency applications.
