The rotary encoder is a rotational displacement into a stream of digital pulse signal indicating a rotation sensor, the rotary pulse encoder can be used to control the angular displacement, if the rotary encoder strip or in combination with the screw gear together, can also be used to measure linear displacement.
　　After the rotary encoder generates an electrical signal from the speed control is set CNC, programmable logic controller PLC, control system to deal with. These sensors are used in the following areas: machine tools, material processing, motor feedback systems, and measurement and control equipment.
　　Rotary encoder angular displacement conversion using the photoelectric scanning principle. Reading system is based on the rotation of the radial indexing plate, the indexing consists of alternating opaque and translucent window windows constructed. This whole system is irradiated with an infrared light source vertically, so put the image on a plate light projected onto the surface of the receiver, the receiver is covered with a grating, said collimator device, and it has a disc the same window.
　　The rotary encoder has a high reliability, environmental adaptability, excellent control performance characteristics. Become the first choice of our customers. It can be widely used in food packaging, textiles, and other small machinery and equipment industry, the rotary encoder has the following features:
　　1, the use of open-loop flux vector, V / F control mode.
　　2, automatic torque boost and automatic slip compensation function.
　　3, support for Simple PLC or Multi-speed terminal support 7-segment; 7-segment can be independently set acceleration and deceleration time and run-time running direction.
　　4, low impatient tone, the carrier frequency can be adjusted from 1KHz-15KHz.
　　5, two acceleration and deceleration time and two S curve slow acceleration and deceleration.
　　Rotary encoders enable control system running at low speed, in fact, can better improve work efficiency. Functional safety rotary encoder drive inverter can be reliably achieve this goal.
