PLC (Programmable Logic Controller) and VFD (Variable Frequency Drive) play an important role in industrial production and technological development. They have been widely used in the field of industrial automation and mechanical automation. The control of the PLC and VFD is quite intelligent and automated, which brings great convenience to industrial production and life. The PLC and VFD will perform intelligent calculation, control and output according to the predetermined program. Today we will focus on how the PLC and the VFD communicate, and in what ways? First, let's take a look at their respective basic structures.

When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.

A rotary encoder converts the angular position or motion of a shaft or axle to analog or digital output signals, so it is also called a shaft encoder. Absolute encoder and incremental encoder are the two main types. Rotary encoders are applied widely, including situations which require monitoring or control, and mechanical systems. So how to use a rotary encoder?

The wheel speed sensor is used to test the wheel speed of a car. For modern vehicles, wheel speed is essential. The vehicle dynamic control (VDC) system, vehicle electronic stability program (ESP), anti-lock braking system (ABS) all require wheel speed information. So the wheel speed sensor is one of the most critical sensors in modern society. Considering the actual factors such as the working environment and the size of the wheel, the electro-magnetic induction sensor and hall type wheel speed sensor are mainly used.
