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.
