Main Machine Features
Uses a servo motor, servo controller, and matching control unit as the drive component; long motor lifespan.
Hollow gear reduction system with low power consumption, low noise, high efficiency, and high reliability.
Zhongtai data acquisition card ensures long-term testing accuracy.
Direct-insert transmission device provides high positioning accuracy, long lifespan, low friction, capable of high-speed operation and reversible rotation; greatly improves machine displacement and speed accuracy.
Position limit function enhances safety and convenience for tests requiring restricted travel.
Wide measurement range suitable for multiple international standards.
Integrated design: Regardless of machine configuration, computer parameters can be modified and permanently saved without circuit adjustments.
High-precision return positioning ensures accurate return to the start position regardless of return speed, improving testing efficiency.
Common parameter memory function (e.g., test speed), allowing the machine to start with preset parameters.
Flexible operation: Supports continuous and jog modes for user convenience in different situations.
Multiple safety protections: Adjustable upper and lower limit protection, emergency stop, etc.
