Functional features

High-precision control

Encoder feedback: It supports various types of encoder feedback, such as incremental encoder and absolute encoder, and the highest resolution can reach millions of pulses/revolution. Through real-time acquisition of encoder feedback signals, the driver can accurately monitor the position, speed and angle information of the motor and carry out closed-loop control according to preset commands to achieve high-precision motion positioning and speed regulation. For example, in precision machining equipment, using high-resolution encoder feedback, the positioning error can be controlled at the micron level to meet the demand for high-precision machining.

Error compensation technology: A variety of error compensation algorithms are built-in, such as backlash compensation and pitch error compensation. The backlash compensation function can effectively eliminate the influence of the gap between mechanical transmission parts (such as gears and screws) on the movement accuracy; the pitch error compensation corrects the pitch error that exists in the manufacturing and installation of ball screws to further improve the accuracy of linear movement and repeatability of positioning accuracy. Through these error compensation techniques, to ensure that the equipment in the long-term operation of the process has always maintained high precision motion performance.

Multi-axis co-operative control

Synchronous control mechanism: when applied to multi-axis linkage system, the drive can communicate with other drives at high speed through CANopen and other fieldbus protocols to achieve precise synchronous control between multiple axes. In gantry-type machining centres, synchronous control of two or more drive axes ensures that the beam remains horizontal during movement, avoiding machining errors caused by inter-axis asynchrony; in multi-joint robot systems, it achieves coordinated movement of joint motors, completing complex spatial trajectory planning and action execution.

Master-slave control mode: It supports master-slave control mode, which can designate one driver as the master driver and other drivers as the slave drivers. The master drive generates motion control signals according to the commands from the host computer and sends them to the slave drives, which follow the signals from the master drive. This control mode is suitable for scenarios that require multi-axis coordination to complete specific tasks, such as multi-roller synchronous drive in printing machinery, multi-axis linkage control in textile machinery.

Safety protection mechanism

Electrical protection: Built-in over-current protection, over-voltage protection, under-voltage protection, overheating protection and other electrical protection functions. When the driver detects that the current exceeds the rated value, the input voltage is abnormal or the internal temperature is too high, it will immediately trigger the protection mechanism to cut off the power output, preventing the motor and the driver from being damaged due to electrical failure. For example, when the motor is blocked or the load is suddenly increased resulting in a sharp rise in current, the overcurrent protection function can be acted within milliseconds to prevent the drive and motor from burning due to overheating.

Mechanical protection: with motor overload protection and mechanical limit protection. By monitoring the load current and torque of the motor, the drive can automatically reduce the output power or stop running when overload is detected, preventing the motor and mechanical transmission parts from being damaged due to overload; the mechanical limit protection can be coordinated with the external limit switches, so that the drive stops the motor running immediately when the motor movement reaches the preset limit position, avoiding the collision or damage of the mechanical structure due to overtravelling.

Safe communication protocols: It supports the extension of safety-related communication protocols, such as PROFIsafe, etc., and can communicate with safety PLCs or other safety devices to achieve safe interlock control. In the automated production line, when an emergency is detected (such as personnel entering a dangerous area), the safety stop function of the drive is quickly triggered through the safety communication protocol to ensure the safety of personnel and equipment.

Flexible configuration and commissioning

Parameter setting: Provide a wealth of parameter setting options, the user can through the drive's operating panel, dedicated commissioning software or the host computer communication for parameter configuration. Parameters cover motor parameters (such as rated power, rated speed, pole number), control parameters (such as PID gain, speed loop bandwidth), communication parameters (such as baud rate, node address) and other aspects. Through the reasonable setting of these parameters, the drive can be matched with different types of motors and application scenarios, giving full play to the performance of the device.

Debugging tools: the matching provides powerful debugging software, such as ABB's DriveWindow and so on. The software has an intuitive user interface, supports online monitoring of the operating status of the drive (such as current, voltage, speed, temperature, etc.), real-time display of the motor's motion curve and control parameters; with fault diagnostic functions, can quickly locate the cause of the drive and motor faults, and provide the appropriate solutions; also supports the parameter backup and restoration function, which facilitates the user in the process of equipment maintenance and upgrading of the rapid configuration of the Parameters.

Plug and Play function: For some standardised application scenarios, the drive supports Plug and Play function, users only need to carry out simple wiring and basic parameter settings, you can quickly realise the matching operation of the drive and the motor, which greatly shortens the debugging time of the equipment and improves the efficiency of project implementation.

Communication compatibility

Protocol expansion capability: In addition to the standard RS485, Modbus, CANopen protocol, the drive also supports the communication expansion module to achieve access to other industrial communication protocols, such as EtherCAT, PROFINET and so on. This protocol expansion capability enables it to be seamlessly integrated into automation control systems of different brands and architectures to meet the diverse system integration needs of users.

Data interaction and monitoring: Through the communication interface, the drive can interact with the host computer or other intelligent devices in real-time data to achieve remote monitoring and control. Users can read the operating parameters and fault information of the drive in real time through the software of the host computer, and remotely set the control commands and parameters; the data of the drive can also be uploaded to the industrial Internet platform, so as to carry out predictive maintenance on the operating status of the equipment by using the big data analysis and artificial intelligence technology to improve the reliability and utilisation rate of the equipment.
