thereby controlling external devices or circuits.
There are three basic types of air valve drivers: whole step, lightning pool, and subdivision. The key difference depends on the linearity of the current of the motor electromagnetic coil (i.e. excitation method).
1. Whole step driver
In the entire operation, the same stepper motor can be equipped with both a whole/lightning tank driver and a subdivision driver, but the actual operation effect is different. The air valve driver excites the two electromagnetic coils of the two-phase stepper motor in a cyclic system according to pulse/direction commands (setting the current for charging the electromagnetic coil battery). Each pulse of this type of driver method will cause the motor to move by a basic pitch angle of 1.80 degrees (there are currently 200 pitch angles per circle for a standard two-phase motor).
2. Yuelei Pool Drive
When single-phase electric excitation is applied, the motor drive shaft stops at the entire step position. After receiving the next pulse, if the driver excites the other phase and maintains the original excitation state, the motor drive shaft will move by one and a half transverse angles and stop in the middle of two adjacent entire step positions. In this cyclic system, single-phase electricity is applied to the two-phase electromagnetic coils, and then the two-phase excitation stepper motor will rotate using a lightning pool method of 0.90 degrees per pulse. All whole/cross lightning pool drives can implement whole step and cross lightning pool drives, which are selected by the dial of the drive dip switch. Compared with the whole step method, the lightning pool method has the advantages of double high accuracy and less vibration during low-speed operation. Therefore, when applying the whole/lightning pool driver, the lightning pool method is generally used.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00594G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
