Servo positioning control is implemented in the PLC and implemented in the servo controller
I have a set of 300 painful DP communication control CU310DP servo drive, but when I return to the proximity switch, sometimes I can't stop positioning in time, I will move backwards for a distance, the proximity switch is OK, I don't know what is going on, which ones Places will affect.
A: Servo positioning control can be implemented in the PLC or in the servo controller. It is realized by PLC, and can choose 317-T process type CPU and built-in positioning control function. The PLC sends a speed command to the servo through communication, and takes the servo feedback to the PLC to realize the position loop control in the PLC. This method requires CPU and communication speed. The servo controller implementation is based on the integrated position control function in the controller. Siemens' old 611U and new S120 controllers are integrated with position control. The realization process is that the PLC writes the target position, speed and other parameters to the corresponding parameters of the servo controller. Then, the control word triggers a call of a motion block of the servo controller, and the servo controller completes a positioning according to the data stored in the parameter. The positioning process is controlled by the servo controller and does not require PLC participation. After the positioning is completed, the servo drive returns a positioning completion signal to the PLC. This method does not require high communication speed. PLC can use ordinary PLC with DP port.
The correct harness can improve the overall performance of the different headlight parts and increase the lighting output of the headlights. Some harnesses are designed to complement higher performance bulbs. So if you have recently upgraded your headlights, you might need a new harness to keep the new lights performing efficiently. When looking for a new harness, you need to be sure that all the parts of the headlight wire harness kit are of the finest quality-not only the wires but as well as the relays, sockets, and terminals. The parts should be tough and must not be susceptible to burning. Also, check whether the harness is compatible with your vehicle.
