4、 Working principle

As the core power drive unit of industrial servo systems, YASKAWA JZNC-XU01B servo drive and amplifier works based on the full process servo drive logic of "instruction reception signal processing power amplification drive control state feedback fault protection". Firstly, the servo drive and amplifier receive control commands (such as position commands, speed commands, torque commands, etc.) from the motion controller or PLC through interfaces such as MECHATROLINK-III and RS-485. At the same time, they receive real-time operating data of the servo motor (such as actual position, actual speed, motor speed, etc.) through the encoder interface; Subsequently, the internal high-performance servo control chip analyzes and processes the received instructions and feedback data, and generates accurate driving signals by combining preset control parameters and algorithms; Next, the driving signal is amplified through an internal power amplification circuit, and the adapted voltage and current are output to the servo motor to drive it to move according to the set parameters; At the same time, the servo drive and amplifier collect real-time operating status data of the servo motor (such as armature current, winding temperature, etc.), compare and analyze it with the set parameters, and adjust the driving signal in a timely manner if there is a deviation; In addition, the internal fault diagnosis and protection circuit continuously monitors the operating status of the entire system. Once abnormalities such as overcurrent, overvoltage, and overheating are detected, the protection mechanism is immediately triggered to cut off the power output and issue an alarm signal, ensuring 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 input voltage is consistent with the rated voltage of the servo drive and amplifier (AC 200-240V) 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 internal circuits 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: Servo drivers and amplifiers need to be installed in industrial control cabinets, away from strong electromagnetic interference equipment such as welding machines and high-power motors, to avoid electromagnetic interference causing a decrease in driving accuracy or communication abnormalities; The installation location should ensure good ventilation and maintain a distance of ≥ 30mm 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, motor power interfaces, encoder interfaces, and expansion module interfaces according to the wiring manual, strictly prohibit misconnection or mixing, and avoid permanent damage to servo drives, amplifiers, or servo motors; Ensure that the terminals are securely fastened during wiring to prevent loose connections that may cause poor contact or abnormal power transmission; Special shielded cables should be used for power cables and signal cables, with a distance of ≥ 300mm between them to reduce signal interference; The servo drive and amplifier 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 parameter configuration must be completed through the supporting software, including motor model adaptation, control mode selection, position/speed/torque parameter setting, communication protocol configuration, protection parameter setting, etc. After the parameter configuration is completed, a trial run test must be conducted to confirm that there are no abnormalities before it can be officially put into use; It is prohibited to arbitrarily modify the core drive parameters to avoid causing abnormal movement of the servo motor.

-Regular maintenance: Regularly check the operating status of servo drives and amplifiers, including indicator light status, cooling fan operation, terminal tightness, cable damage, etc; Regularly clean the dust on the surface of the control cabinet and equipment to ensure smooth heat dissipation; Regularly backup driver parameters 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.
