Working principle

The YASKAWA JZNC-MRK12-1E control machine is the core control unit of the robot automation system, and its working principle is based on the full process industrial control logic of "instruction reception trajectory planning multi axis synchronous control state feedback fault handling". Firstly, the control machine receives job instructions (such as motion trajectory, job parameters, etc.) from the upper computer or console through interfaces such as EtherCAT and Ethernet. At the same time, it receives real-time operation data of the robot body and servo drives (such as joint position, operating speed, load current, etc.) through dedicated interfaces; Subsequently, the internal high-performance multi-core processor parses the received instructions, combines preset motion parameters and trajectory planning algorithms to generate accurate multi axis synchronous control instructions, and transmits them in real-time to each servo drive through the EtherCAT high-speed bus; Next, the servo drive drives the robot joint motor to move along the set trajectory according to the control instructions, completing the designated task; At the same time, the control machine collects real-time data on the robot's operating status and sensor feedback information, compares and analyzes it with the set parameters, and adjusts the control instructions in a timely manner if there is a deviation; In addition, the internal fault diagnosis circuit continuously monitors the operating status of the entire system. Once an abnormality is detected, the alarm mechanism is immediately triggered, fault information is recorded, and corresponding protective actions are executed according to the fault type (such as emergency shutdown, switching redundant links, etc.) to ensure the safety of equipment and personnel.

Installation and usage precautions

（1） Installation 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 control machine (AC 100-240V) to avoid voltage fluctuations beyond the allowable range; It is recommended to install surge protectors and power filters at the power input end to prevent damage to the internal circuit of the control machine caused by power grid surge voltage and electromagnetic interference; If configuring power redundancy, it is necessary to ensure that the parameters of the two power sources are consistent to ensure smooth switching; When not in use for a long time, the power should be disconnected to avoid component aging caused by standby current.

-Installation environment requirements: The control machine should be installed in an industrial control cabinet, away from strong electromagnetic interference equipment such as welding machines and high-power motors, to avoid electromagnetic interference causing a decrease in control accuracy or communication abnormalities; The installation location should ensure good ventilation and maintain a distance of ≥ 50mm from other equipment to ensure smooth heat dissipation; It is strictly prohibited to install in environments with direct sunlight, high temperature and humidity, high dust or corrosive gases to extend the service life of the equipment.

-Correct wiring and grounding: Strictly distinguish power interfaces, communication interfaces, robot specific interfaces, and expansion module interfaces according to the wiring manual, strictly prohibit misconnection or mixing, and avoid permanent damage to the control machine or associated equipment; Ensure that the terminals are securely fastened during wiring to prevent loose connections or communication interruptions; Special shielded cables should be selected for communication cables, and the distance between power cables and signal cables should be ≥ 300mm to reduce signal interference; The control machine must be reliably grounded with a grounding resistance of ≤ 4 Ω to prevent the risk of electric shock or electromagnetic interference.

（2） Precautions for use and maintenance

-Parameter configuration specification: Before the first use, the system parameters need to be configured through the supporting software, including robot model adaptation, axis parameter calibration, communication protocol settings, motion trajectory parameter settings, etc. After the parameter configuration is completed, a trial run test needs to be conducted to confirm that there are no abnormalities before it can be officially put into use; Prohibit arbitrary modification of core control parameters to avoid abnormal robot motion.

-Regular maintenance: Regularly check the operating status of the control machine, including the status of indicator lights, the operation of the cooling fan, and the tightness of the wiring terminals; Regularly clean the dust on the surface of the control cabinet and control machine to ensure smooth heat dissipation; Regularly backup control programs and operational data to prevent data loss; It is recommended to conduct a comprehensive system inspection and maintenance every 6 months.

-Fault handling specifications: When a fault occurs, it is necessary to first check the fault code and fault log, and investigate the cause of the fault according to the instruction document. It is strictly prohibited to forcefully start the equipment without troubleshooting; When replacing components, it is necessary to use Yaskawa original parts to ensure equipment compatibility and operational reliability; Complex faults require maintenance by professional technicians.
