I. What is an industrial robot control cabinet?
The DX100 industrial robot control cabinet mainly consists of a main controller, servo drives, and a built-in PLC. Besides controlling robot movements, it can also perform input and output control. The main controller generates a working program based on information provided by the teach pendant, calculates the motion commands for each axis, and sends them to the servo drives. The servo drives process commands from the main controller to generate servo drive current and drive the servo motors. The built-in PLC is mainly used for input and output control. When the robot is working, the control cabinet sends welding commands to the welding machine through the input/output interfaces and monitors the welding machine's operating status. It also controls peripheral devices. Its main functions are as follows:
1. ARM (Advanced Robotics Movement) Control
2. Multi-axis/composite system control;
3. High-precision trajectory control;
4. Optimal acceleration/deceleration control;
5. Damping control;
6. Track stability control;
This advanced control helps improve work quality, reduce idle travel time, decrease system interruptions, shorten teaching time, and improve security.
II. Precise control of high-speed cornering
The trajectory control of the industrial robot has been improved, and speed variations are kept to a minimum. Furthermore, optimization features such as rapid approach to reduce idling time have been implemented.
III. Collision Detection Function of Industrial Robots
This function effectively detects collisions between industrial robots and external equipment and immediately stops the robot's operation to protect both the robot and affected equipment from damage. To differentiate between collisions during normal operation and when the industrial robot experiences significant dynamic loads, collision intensity standards can be preset. The industrial robot will continuously monitor the load. When the load value exceeds the standard set in Annex 2-1, it will be considered an abnormal collision and the robot will stop immediately. This standard is set in the collision level file. Nine files are available.
In the operating procedure, the collision intensity judgment standard can be changed at any time according to the nature of the operation. That is, different standards can be selected in different program segments, i.e., the "SHCKSET" command is used to modify the setting standard. For example, during assembly operations, because the robot's operating force is relatively large, the judgment value is set slightly higher to avoid false alarms. In non-contact operations, the judgment value can be set lower to more sensitively detect accidental collisions, providing good protection. Customers can also decide whether the collision detection function is effective based on specific circumstances. When a collision is detected and the machine stops, it can be easily reset. After the cause of the collision is eliminated, the industrial robot can continue operating.
