Core technology: Achieving nanoscale control

5.1 SERVO HRV Control

By combining the latest hardware and software technologies such as HRV+servo control, high-speed and high-precision control at the nanoscale can be achieved. Even if the mechanical resonance frequency changes, the HRV filter can automatically follow and suppress the mechanical resonance.

5.2 SPINDLE HRV Control

By quickly sampling the current control loop, high gain control and low heat generation during high-speed rotation can be achieved. Based on the inertia of the workpiece or tool, use the optimal deceleration level for optimal orientation. Support nano interpolation in position control, enabling the spindle to achieve nano CNC system like a feed axis.

5.3 Servo Learning Control

Servo learning control can achieve high-speed and high-precision machining, especially when used in conjunction with linear motors. By combining high-precision linear motors with servo learning control, it is possible to achieve shorter machining cycles for non spherical workpieces through turning rather than milling.

5.4 AI servo adjustment

AI feedforward is a high-dimensional feedforward control that can accurately describe the characteristics of machine tools. Applying machine learning to parameter decision-making processes can easily achieve advanced feedforward control. This function can suppress low-frequency vibrations during acceleration and deceleration, which helps achieve fine surface processing.

Intelligent maintenance and fault diagnosis

6.1 Fault prediction function

Leakage detection function: measure the insulation resistance of the motor and detect insulation degradation.

Capacitor inspection function: Measure the capacitance of the main circuit of the servo amplifier and detect the decrease in capacitance.

Fan motor speed detection function: measure the servo amplifier fan motor speed and detect the decrease in speed.

Brake inspection function: measure the status of the brake and detect brake faults.

6.2 Easy to maintain design

Fan quick replacement: The fan can be easily replaced from the front without removing the amplifier from the electrical control cabinet, shortening maintenance time.

One click connector: The power and signal connectors of the servo motor can be installed and removed with one click, reducing motor maintenance time and improving the reliability of replacement work.

6.3 Fault diagnosis function

Cooperate with 30i-B series CNC and 0i-F series CNC to provide fault diagnosis function:

Fault diagnosis guide screen: According to the fault diagnosis process, help identify the cause of the alarm.

Fault diagnosis monitoring screen: monitors the servo circuit and spindle status during normal operation, and can latch data when an alarm occurs.

Fault diagnosis graphic screen: displays the waveform observed when a servo or spindle alarm occurs.

6.4 Encoder Communication Inspection Circuit

When a communication alarm occurs in the encoder, the fault source may involve three parts: the encoder, feedback cable, and servo amplifier. The encoder communication inspection circuit can output signals compatible with the encoder, helping to quickly identify faulty components and shorten downtime.
