I. Overview

B&R 8AC120.60 - 1 is a high-performance ACOPOS plug-in module that plays a crucial role in motion control and motor drive systems. It is mainly used to connect encoders with ACOPOS servo drives, providing the system with accurate position feedback and speed monitoring data to ensure high precision and stability of equipment operation. As an important member of B&R's automation product system, it is widely used in various industrial production scenarios due to its excellent performance, reliable quality, and good compatibility, helping enterprises improve production efficiency and ensure product quality.

II. Functional Characteristics

Adaptability to multiple types of encoders: This module shows high compatibility with encoder types, especially good at working with Endat encoders, and can also efficiently adapt to simple incremental encoders with sine incremental signals. Whether it is a single-turn or multi-turn Endat encoder, with regular line counts or special line counts (such as 512 lines, 32 lines, 16 lines, etc.), 8AC120.60 - 1 can accurately connect and process data. For example, in high-precision semiconductor manufacturing equipment, it can connect to an Endat 2.1 encoder to accurately obtain the position information of the motor rotor, ensuring the motion accuracy of the equipment at the micro-nano scale.

Efficient data processing and transmission: It has built-in advanced data processing circuits and algorithms, which can quickly parse, convert, and process the signals from the encoder. The processed key data such as position and speed are timely transmitted to the ACOPOS servo drive and other related control systems through a stable and reliable communication link. In high-speed automated production lines, it can feed back the real-time position information of the motor to the drive at an extremely fast speed, ensuring that the drive can quickly adjust the output to maintain stable operation and precise control of the equipment.

Real-time status monitoring and fault diagnosis: It has a powerful encoder monitoring function, which can monitor and analyze the working status of the encoder in real-time. Once an abnormality is found in the encoder (such as signal loss, data error, connection failure, etc.), it can quickly issue an alarm and initially locate the cause of the fault through the built-in diagnostic algorithm. This feature is particularly important in large industrial production equipment, which can effectively avoid production interruptions caused by encoder faults, provide early warning for timely maintenance, reduce equipment downtime, and improve production efficiency.

Flexible interface design: It uses a 15-pin D-type female connector as the module-side connection interface, which is compact and reliable in design, facilitating physical connection with the encoder. At the same time, it supports differential signal transmission, which effectively improves the anti-interference ability of signal transmission, ensuring that signals can be transmitted stably and accurately in complex industrial electromagnetic environments. In practical applications, it can easily achieve quick connection and adaptation with encoders of different brands and models, reducing the difficulty of system integration.

III. Technical Parameters

Power supply and power consumption: The power consumption of the module is closely related to the type of connected encoder. For example, when connected to an Endat single-turn, 512-line encoder, the maximum power consumption is 2.3W; when connected to an Endat multi-turn, 512-line encoder, the maximum power consumption is 3.1W, etc. This power consumption design fully considers the energy needs in different application scenarios, achieving rational use of energy while ensuring high-performance operation.

Electrical isolation: An electrical isolation mechanism is set between the encoder and ACOPOS, which effectively prevents the spread of electrical interference between different devices, ensures the electrical independence between various parts of the system, and improves the safety and stability of the entire system. This isolation design can ensure the accuracy of measurement data and the reliability of equipment operation in industrial environments with high electromagnetic interference.

Encoder cable length: It supports encoder cable connections up to 50m in length, providing great flexibility for equipment installation and layout. In large industrial plants or complex production lines, even if the physical distance between the encoder and the module is relatively long, the quality of signal transmission can be ensured, facilitating system integrators to carry out reasonable wiring according to the actual site conditions.

Signal parameters
Sine/cosine input: The signal transmission adopts differential signal and symmetric transmission mode, with a signal frequency range from DC to 300kHz (-3dB) and DC to 400kHz (-5dB). The differential voltage range is 0.5 to 1.25Vss, the maximum common-mode voltage is ±7V, and it is equipped with a 120Ω terminal resistor. These parameters ensure the accurate acquisition and processing of sine/cosine signals, providing a basis for high-precision position and speed measurement.

Reference input: The signal transmission also adopts differential signal and symmetric mode, with a low-level differential voltage ≤ -0.2V, a high-level differential voltage ≥ +0.2V, a maximum common-mode voltage of ±7V, and a terminal resistor of 120Ω. Through stable reference signal input, the accuracy and consistency of system measurement are guaranteed.

Serial interface: The signal transmission adopts a synchronous mode, with the protocol being RS485 and the baud rate being 625kbaud. High-speed and stable serial interface communication ensures efficient and smooth data interaction between the module and external devices, meeting the real-time requirements of industrial automation.

Environmental adaptability
Temperature: The operating temperature range is nominally 5 to 40°C, up to 55°C; the storage temperature range is -25 to 55°C; the transportation temperature range is -25 to 70°C. The module can maintain stable performance under different ambient temperatures, working normally whether it is near a high-temperature industrial furnace or during transportation in a cold storage environment.

Relative humidity: The relative humidity range during operation is 5 to 85%, during storage is 5 to 95%, and during transportation, it can reach a maximum of 95% under 40°C. Good humidity adaptability enables the module to avoid faults caused by humidity issues in humid production workshops or during transportation with variable humidity, ensuring long-term stable operation of the equipment.
