The SureServo2 AC servo motor is designed for industrial applications, offering precise control and robust performance. This device manual provides comprehensive instructions for installation, operation, and maintenance, ensuring safe and efficient use.
The SureServo2 servo drive and motor system are engineered to provide accurate motion control in various industrial settings. The servo drive controls the AC servo motor's operation, converting electrical energy into mechanical motion with high precision. It manages the motor's torque, speed, and position, making it suitable for applications requiring dynamic and responsive movements.
A key function of the SureServo2 system is its ability to handle regenerative energy. When the motor's direction of torque differs from its direction of rotation, energy generated from the load returns to the servo drive. This energy is converted into electricity and stored in the DC Bus capacitor bank, increasing its voltage. To prevent overvoltage, this excess energy is consumed by a regenerative resistor. Servo drives up to 3kW feature a built-in regenerative resistor, while external regenerative resistors can be used for higher power applications or when the built-in capacity is exceeded. The drive's firmware calculates energy regeneration, using half the wattage value for protection.
The system also incorporates a braking mechanism, primarily used for motions in the Z-axis direction to prevent mechanisms from falling due to gravity. The brake engages (holds the motor) when no power is applied to its wires and disengages (allows the motor to spin) when power is applied. The servo drive controls the brake via a digital output (DO), with configurable delay times to ensure proper operation. This prevents the mechanism from falling and reduces the motor's resistance output, thereby extending its lifespan.
For electromagnetic compatibility (EMC), the SureServo2 system is designed to conform to EMC test specifications. It includes provisions for EMI filters and shielded cables to mitigate high-frequency noise generated during operation. The EMI filter, when correctly installed, helps eliminate interference with peripheral equipment through conduction or radiation, ensuring stable circuit operation.
The SureServo2 system offers several usage features designed to optimize performance and ease of integration. During installation, it is crucial to mount the servo drive vertically on a wall, ensuring the heat sink base is properly oriented for optimal heat dissipation. Adequate space around the drive is necessary for ventilation and cooling, preventing overheating and potential malfunction. For models up to 400W, the maximum operation temperature is 55°C, while models 750W and above can operate up to 60°C, with output current reduction at higher temperatures.
Safety precautions are paramount. Users must fully understand the motor specifications and operation manual before connecting the motor to any equipment. This includes proper handling during removal or installation, avoiding impact to the motor shaft, and keeping axial or radial loads within allowable ranges. The motor should not be used, installed, or stored in humid environments or those containing corrosive gases or liquids.
Wiring practices are critical for reliable operation. If the connection between the servo drive and servo motor exceeds 20 meters, increasing the gauge of the connecting wires and encoder cable is recommended. Incorrect wiring, especially of the motor brake voltage or encoder signal and power cables, can lead to abnormal operation or damage. To prevent capacitive coupling and noise, motor power cables should be isolated from encoder power and signal cables. The AC servo motor must be correctly grounded, and the encoder connector should not undergo high-voltage component tests.
The system's regenerative resistor selection is a key usage feature. For drives up to 3kW, the built-in resistor is sufficient for many applications. However, for higher power or dynamic braking requirements, external regenerative resistors can be connected. The manual provides detailed calculations for determining the required resistance and wattage based on load inertia, operation cycle, and motor speed. This allows users to select appropriate external resistors to dissipate excess energy effectively, preventing overvoltage and ensuring stable operation.
The use of ferrite rings is another important feature for noise suppression. These rings, typically made of Mn-Zn ferrite, increase impedance at higher frequencies, acting as low-pass filters to suppress high-frequency noise in power and signal cables. Winding multiple turns of wire onto the ferrite ring enhances its inductance and filtering capability, improving signal transmission stability.
Maintaining the SureServo2 system involves adhering to specific guidelines to ensure longevity and optimal performance. Proper storage conditions are essential before installation, requiring the product to be kept in its shipping carton within an ambient temperature range of -20°C to +65°C and a relative humidity of 0% to 90% in a non-condensing environment. Corrosive gas environments should be avoided.
Regular checks of the motor shaft are necessary, especially if storing the motor for extended periods. Although rust-proof oil is applied during manufacturing, it should be reapplied every three months if the motor is stored for more than six months, as the shaft material is not inherently rust-proof.
The manual emphasizes that SureServo2 servo motors do not have user-replaceable parts. Disassembling the motor or changing its components will void the warranty and may lead to permanent damage or malfunction. Splashing water or oil on the product should also be avoided.
For the braking mechanism, it is important to note that the built-in brake is for clamping or holding the rotor or shaft stationary, not for stopping or decelerating the motor. Another safety stopping device for the machine should be installed. While the brake lining may generate noise during operation, this is a normal characteristic and does not affect the motor's function. If any abnormal odor, noise, smoke, vapor, or vibration occurs during motor operation, the motor should be stopped, and power turned off immediately.
To ensure the best performance of the EMI filter, the servo drive and EMI filter should be mounted on the same unpainted metal plate, with wiring kept as short as possible, and the metal plate well-grounded. The motor cables should have braided shielding, and the shield on both ends of the motor cable must be grounded with the shortest possible cable length and largest contact area. Any protective paint on the U-shape saddle EMC cable clamp and metal plate should be removed to ensure good contact. These practices contribute to the overall reliability and longevity of the system by minimizing electrical interference.
