Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Safety precautions Safety definition: Safety precautions are divided into the following two categories in this manual: During the installation, commissioning and maintenance, please read this chapter carefully, and follow the safety precautions herein. Our company will not be liable for any injury or loss arising from nonconforming operations. Precautions Before installation: Danger 1. Do not install the product in the case of water in the package or missing or damaged components found in unpacking! 2. Do not install the product in the case of inconsistency between the actual product name and identification on the outer package.

Attention 1. Handle with care; or the product may be damaged! 2. Do not use the servo driver if it is damaged or has some parts missing; otherwise injuries may be caused! 3. Do not touch the components of the control system with your hands; otherwise, there is a danger of static damage! During installation: Danger 1. Please install the inverter on a metal retardant object (e.g. metal) and keep it away from combustibles; otherwise, a fire may be caused! Attention 1. Never allow wire connectors or screws to fall into the servo driver; otherwise the servo driver may be damaged! 2. Install the servo driver in a place where it is subject to low vibration and no exposure to direct sunlight. 3.

When the servo driver is placed in a relatively closed cabinet or space, reserve some installation clearance for sound heat dissipation. During wiring: Danger 1. Wiring shall be performed by a professional electrical engineer following instructions provided in this manual; otherwise unexpected danger may be caused! 2. Install a circuit breaker between the servo driver and the power supply for fire protection! 3. Before wiring, make sure that the power supply is in the zero energy status; otherwise, electric shock may be caused! Ground the servo driver correctly for protection against electric shock! 4. Connect the ground terminal reliably; otherwise electric shock and fire may be caused!

Attention 1. Never connect the input power to an output terminal (U, V, W) of the servo driver. Pay attention to the marks of wiring terminals, and connect wires correctly! Otherwise the servo driver may be damaged! 2. Make sure that the lines meet the EMC requirements and local safety standards. For wire diameters, refer to the recommendations. Otherwise, an accident may occur! 3. Never connect the braking resistor directly between the P+ and - terminals of a DC bus. Otherwise, a fire may be caused! 4. Tighten the terminals with a screwdriver of specified torque; otherwise, there is a risk of fire. 5. Never connect the phase-shifting capacitor and LC/RC noise filter to the output circuit.

6. Do not connect the electromagnetic switch and electromagnetic contactor to the output circuit. Otherwise action of the overcurrent protection circuit of the servo driver may cause internal damage to the servo driver in severe cases. 7. Never disassemble connecting cables inside the servo driver; otherwise damage may be caused to the inside of the servo driver. 2 Danger: The dangers caused by nonconforming operations may include serious injuries and even deaths; Note: The danger caused by nonconforming operations, including moderate or minor injuries and equipment damage;

Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Before power-on: Attention 1. Make sure that the supply voltage of the input power is consistent with the rated voltage of the servo driver, and that the power input terminals (L1, L2, L3) and output terminals (U, V, W) are correctly wired. Check to ensure there is no short circuit in peripheral circuits connected to the servo driver and all connecting lines are tightened; otherwise damage may be caused to the servo driver. 2. No withstand voltage test needs to be performed on any part of the servo driver, as the test has been performed in the factory. Otherwise, an accident may be caused! Attention 1.

The servo driver shall not be powered on until its cover is installed correctly; otherwise electric shock may occur! 2. The wiring of all peripheral accessories must be in line with the instructions in this manual. All wires should be connected correctly according to the circuit connections in this manual. Otherwise, an accident may occur! After power-on: Danger 1. Never touch the servo driver and its surrounding circuits with wet hands; otherwise electric shock may occur! 2. If the indicator does not get ON or the keyboard has no response after power-on, immediately turn off the power supply.

Never touch the servo driver terminals (L1, L2, L3) and any terminal on the terminal block with your hands or a screwdriver; otherwise electric shock may be caused. Upon turning off the power supply, contact our customer service personnel. 3. Immediately after power-on, the servo driver automatically performs a safety test on external high-voltage circuits. Do not touch the servo driver terminals (U, V, W) or motor terminals; otherwise electric shock may be caused! Attention 1. When parameter identification is required, please pay attention to the danger of injury during motor rotation; otherwise, an accident may occur! 2.

Do not change the parameters set by the servo driver manufacturer; otherwise damage may be caused to the equipment! During operation: Danger 1. Do not touch the cooling fan, radiator, servo motor or discharge resistor to feel the temperature; otherwise burns may be caused! 2. Non-professional technicians must not test signals when the controller is in operation; otherwise, personal injury or equipment damage may be caused! Attention 1. The servo driver in operation should be protected against falling objects; otherwise damage may be caused to the equipment! 2. Do not start or stop the servo driver by turning on or off the contactor; otherwise damage may be caused to the equipment! 3.

Do not touch the rotary shaft of the motor during operation; otherwise injury may be caused! During maintenance: Danger 1. Never carry out repair and maintenance in the live state; otherwise, electric shock may be caused! 2. Cut off power of the main circuit, and perform maintenance and repair of the servo driver after the CHARGE indicator goes off; otherwise residual charges of the capacitor may cause injuries! 3. No repair or maintenance of the servo driver shall be performed by any individual who has not been professionally trained on such repair or maintenance; otherwise personal injury or equipment damage may be caused! 4.

The servo driver, after replacement, shall have parameters set; all plug connections and disconnections shall be handled in the power-off status! Precautions  When a voltage-dependent device or power factor-improving capacitor is present on output side The servo driver outputs PWM waves. Installation of a power factor-improving capacitor or a voltage-dependent resistor for lightning protection on the output side may cause instantaneous overcurrent or even damage to the servo driver; therefore, such installation shall not be used.  Lightning impulse protection The servo driver of this series is equipped with a lightning overcurrent protector for protection against induced lightning.

Yet if the product is installed in a place subject to frequent lightning, installation of an additional lightning protection device before the servo driver is required.  Altitude and derating 3
