4. 설정 및 설치

4.1 Motor Assembly Steps (MKS SERVO28D MT Examp르)

Figure 4: MKS SERVO28D MT Assembly Steps

1. 자석을 모터 축에 설치하고 접착제로 고정하십시오.
2. Use Phillips pan head screws (M2.5*35) and ABS (6mm) to fix the MKS SERVO28D to the motor, and you need to align the 4P terminal with the direction of the motor wire.
3. Connect the 4 wires of the motor to the 4P screw terminal according to the wire sequence of "green, black, blue, red".
   팁: Green: A+, Black: A-, Blue: B+, Red: B-.

4.2 Magnet and Magnetic Encoder Distance Requirements

그림 5: 자석 및 자기 엔코더 거리 요구 사항

• 자석과 엔코더 칩을 평행하게 유지하고, 둘 사이의 간격을 0.5mm에서 3.0mm 사이로 두십시오. 간격이 작을수록 최적의 결과(각도 오차)를 얻을 수 있습니다.
• 자석의 중심은 자기 엔코더 칩의 감지 중심과 일치해야 하며, 편차는 ±0.3mm 이내여야 합니다. 그렇지 않으면 절대 각도 정확도에 심각한 영향을 미칩니다.
• Recommended radial magnet Size: Φ6.00mm, height 2.5mm.
• Recommended distance range between magnet and magnetic encoder chip: 0.5mm-3.0mm.
• The deviation range of the alignment between the magnet center and the magnetic encoder chip sensing center is: -0.3mm~0.3mm.

4.3 배선도

General Wiring Tip: In order to reduce bus interference, the host-GND and the motor-GND must be connected together, and RS485/CAN signals are transmitted using shielded twisted pairs.

Note: Single slave communication does not need 120 ohm terminal resistor.

5. 사용 설명서

The MKS SERVO28D/35D drivers can be controlled via pulse signals or serial communication (RS485/CAN). For advanced configuration and monitoring, a dedicated Control TOOL software is available.

5.1 Control Tool Software

The Control TOOL software allows users to set system parameters, perform motor control, and monitor motor status. It supports features like factory reset, setting limit switches, and adjusting acceleration parameters.

Figure 10: MKS SERVO D-SERIES Control TOOL Interface

중요한: After clicking 'Factory reset', you need to recalibrate again.

The software allows for:

• 환경: Port, Baud rate, Address.
• 시스템 매개 변수 : CtrMode, MStep, En, Dir, AutoSDD, Protect, MPlyer, UartBaud, UartAddr, UartGRP, UartESP.
• 모터 제어: Enable/Disable driver board, set limit switch (HomeTrig, HomeSpeed, Limit return to zero, Direct return to zero), adjust acceleration parameters (Start ACC, Stop ACC).
• Motor Status Monitor: Direction, Speed, Acceleration, Status.
• Control Motor Rotation Speed: Forward/Reverse, Speed gear.
• Control Motor Position: Speed gear, Pulses.

For detailed instructions on using the Control TOOL and specific parameter settings, please refer to the official user manual available on GitHub.

6. 유지관리

To ensure optimal performance and longevity of your MKS SERVO28D/35D driver, follow these general maintenance guidelines:

• 청소: 드라이버와 모터에 먼지와 이물질이 묻지 않도록 하십시오. 부드럽고 마른 천으로 닦으십시오. 액체나 용제는 사용하지 마십시오.
• 점검: Periodically check all wiring connections to ensure they are secure. Inspect for any signs of wear, damage, or loose components.
• 환경: 기기 손상을 방지하기 위해 지정된 환경 조건(온도, 습도) 내에서 기기를 작동하십시오.
• 펌웨어 업데이트: Check the official Makerbase GitHub repository for any available firmware updates that may improve performance or address issues.

7. 문제 해결

If you encounter issues with your MKS SERVO28D/35D driver, consider the following general troubleshooting steps:

• 전원 확인: 전원 공급 장치가 지정된 볼륨 내에 있는지 확인하십시오.tage range (12V-24V) and provides sufficient current.
• 배선 확인: Double-check all wiring connections against the diagrams in Section 4.3. Ensure correct polarity and secure connections.
• 의사소통 문제: If using RS485 or CAN, verify the communication settings (baud rate, address) in the Control TOOL match your host controller. Ensure shielded twisted pairs are used for bus signals.
• 운동 동작: If the motor is not moving or moving erratically, check the magnet and encoder alignment (Section 4.2). Verify motor wire connections (A+, A-, B+, B-).
• 소프트웨어 설정: Review parameters in the Control TOOL. A factory reset followed by recalibration might resolve configuration issues.
• 과열: Ensure adequate ventilation around the driver and motor to prevent overheating.

For more specific troubleshooting, refer to the detailed user manual and schematics available on the Makerbase GitHub repository.
