Working principle

The YASKAWA JANCD-JSP04-1 CNC board is the core control unit of the CNC machine tool system, and its working principle is based on the full process CNC control logic of "instruction reception trajectory planning axis linkage control state feedback fault diagnosis". Firstly, the CNC board receives CNC programming instructions (G code, M code, etc.) from the operation panel or upper computer through a communication interface; Subsequently, the internal 32-bit high-performance processor performs high-speed parsing of CNC instructions, combines the parameters of the machined parts to complete trajectory planning and axis motion parameter calculation, and generates position and speed control instructions for each axis; Next, the control instructions are transmitted in real-time to each servo drive through the MECHATROLINK-III high-speed servo communication interface, driving the servo motor to move according to the planned trajectory and achieving multi axis linkage machining; At the same time, the CNC board real-time collects the actual position, speed signals, limit, emergency stop and other auxiliary signals of each axis, compares them with the set values, dynamically corrects control instructions, and ensures machining accuracy; In addition, the internal fault diagnosis circuit continuously monitors the operating status. Once an abnormality is detected, an alarm is immediately triggered and a fault code is recorded to stop the machining action and protect the safety of the equipment and workpiece.

Precautions

-Voltage matching and power protection: Before installation, it is necessary to confirm that the power supply voltage is consistent with the rated voltage of the module (DC 24V) to avoid voltage fluctuations exceeding the allowable range of ± 10%; It is recommended to install surge protectors and filters at the power input end to prevent damage to the internal circuit of the module caused by power grid surges and electromagnetic interference; When not in use for a long time, the power should be disconnected to avoid component aging caused by standby current.

-Safety operation regulations: When wiring, repairing or replacing components, the power must be disconnected first, and touching the terminals while powered on is strictly prohibited to prevent electric shock accidents.

-Correct wiring and communication configuration: Strictly distinguish power interfaces, servo communication interfaces, and I/O interfaces according to the wiring manual, strictly prohibit misconnection and mixing, and avoid permanent damage to the module; Ensure that the terminals are securely fastened during wiring to prevent loose connections or communication interruptions; The servo communication cable should use Yaskawa special shielded cable, and the distance between the power cable and the signal cable should be ≥ 300mm to reduce signal interference; Based on the servo motor model and processing requirements, accurately configure key parameters such as shaft parameters and electronic gear ratios to ensure multi axis linkage accuracy.

-Standardize grounding settings: The grounding terminals must be strictly connected according to local grounding regulations to avoid sharing grounding with welding machines, motors, and other equipment. When multiple modules are used side by side, they must be independently grounded, and grounding wire circuits are prohibited to prevent electric shock or fire risks.

-Professional operation: The parameter setting, system integration, and fault maintenance of modules need to be completed by professional technicians to avoid system failures or equipment damage caused by non professional operations.
