Servo motor encoder signal line

As a crucial “information transmission channel” for closed-loop control of a servo system, the core function of the servo motor encoder signal line is to connect the servo motor’s encoder and driver, accurately transmitting key feedback signals such as the motor rotor’s position, speed, and zero position. The driver receives these real-time signals, dynamically adjusts its output commands, corrects motor operating deviations, and achieves micron-level speed and position control. Simultaneously, some high-end models can transmit extended information such as motor temperature and fault codes, providing real-time diagnostic data for the servo system and preventing malfunctions caused by positioning deviations or abnormal speeds. It is a core component ensuring the high-precision, high-response operation of the servo system. It is compatible with mainstream servo systems from brands such as Yaskawa, Inovance, Delta, and Mitsubishi, including Yaskawa servo drivers and motors, various Inovance servo motor series, and Delta ASDA-B2 series servo drivers. It also adapts to different types of encoders, such as incremental and absolute encoders, covering the signal transmission needs of various encoder count specifications, including 4-line, 5-line, and 14-line encoders. Widely used in high-precision equipment such as industrial robots (six-axis/four-axis robotic arms), CNC machine tools, and five-axis machining centers; compatible with automated production lines such as 3C electronic sorting lines, lithium battery stacking mechanisms, and high-speed labeling equipment for printing and packaging; also suitable for special scenarios such as wind power pitch control systems, rail transit gate control, and semiconductor lithography machines, capable of handling strong electromagnetic interference environments in workshops and adapting to harsh outdoor conditions. Incremental encoders commonly use 2 pairs of twisted shielded core wires (e.g., 2×2×0.18mm²), with a 5-wire economic model suitable for general scenarios; absolute encoders with 14-wire specifications are compatible with protocols such as EnDat2.2, supporting high-resolution transmission of 23 bits or more; for long-distance transmission (>10 meters) scenarios, 2×2×0.25mm² core wires can be selected, and the 4-wire differential model can adapt to long-distance signal transmission requirements of over 50 meters.
