5. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ
5.1 ການຕິດຕັ້ງ
The Danfoss MCI 15 Motor Controller is designed for panel mounting. Ensure adequate ventilation around the heat sink to prevent overheating. Use appropriate fasteners through the mounting brackets shown in Figure 3.4.
5.2 ສາຍໄຟ
Refer to the wiring diagram on the device label (Figure 4.1) for correct connections. Ensure all wiring adheres to local electrical codes and safety standards.
- Power Input (L1, L2, L3): Connect the three-phase power supply to terminals 1/L1, 3/L2, and 5/L3.
- Motor Output (T1, T2, T3): Connect the motor leads to terminals 2/T1, 4/T2, and 6/T3.
- Control Input (A1, A2): ເຊື່ອມຕໍ່ການຄວບຄຸມ voltage ກັບ terminals A1 ແລະ A2.
- Use recommended wire sizes (e.g., 0.75-6mm² or 18-10AWG for power, 0.5-1.5mm² or 20-16AWG for control) and tighten terminals to the specified torque (e.g., 0.5Nm or 4.4lb-in for M3 screws).
5.3 ການຕັ້ງຄ່າເບື້ອງຕົ້ນ
Before initial operation, adjust the potentiometers on the front panel (Figure 3.2) to desired settings:
- Ramp ເວລາຂຶ້ນ: Adjust the 'up' potentiometer to set the motor acceleration time (0-10 seconds).
- Ramp Down Time: Adjust the 'down' potentiometer to set the motor deceleration time (0-10 seconds).
- Kick Start: Adjust this potentiometer to provide an initial torque boost for starting loads.
- Initial Torque: Adjust this potentiometer to set the initial torque level during startup.
6. ຄໍາແນະນໍາການດໍາເນີນງານ
Once installed and configured, the Danfoss MCI 15 Motor Controller operates by applying a controlled voltagເອີamp to the motor, providing a soft start and stop. The motor will accelerate to full speed over the set ramp-up time and decelerate over the set ramp- ເວລາລົງ.
- ນຳໃຊ້ການຄວບຄຸມ voltage to terminals A1 and A2 to initiate motor operation.
- Remove control voltage to initiate motor stop (soft stop).
- Monitor motor performance and adjust ramp times and torque settings as needed for optimal operation.
7. ບໍາລຸງຮັກສາ
Regular maintenance ensures the longevity and reliable operation of the motor controller.
- ທໍາຄວາມສະອາດ: Periodically clean the exterior of the controller, especially the heat sink fins, to ensure proper heat dissipation. Use a dry, soft cloth. Do not use solvents or abrasive cleaners.
- ການກວດກາ: Regularly inspect wiring connections for tightness and signs of wear or damage. Check for any discoloration or unusual odors, which may indicate overheating.
- ສະພາບແວດລ້ອມ: ໃຫ້ແນ່ໃຈວ່າສະພາບແວດລ້ອມການເຮັດວຽກຍັງຄົງຢູ່ໃນຂອບເຂດອຸນຫະພູມແລະຄວາມຊຸ່ມຊື່ນທີ່ກໍານົດ.
8. ການແກ້ໄຂບັນຫາ
If the motor controller does not operate as expected, consider the following basic troubleshooting steps:
- No Motor Start: Verify power supply to the controller and motor. Check control signal to A1/A2. Ensure all wiring is correct and secure.
- Motor overheating: Check for proper ventilation around the heat sink. Ensure the motor is not overloaded. Verify motor parameters are correctly set.
- Incorrect Ramp ເວລາ: Re-adjust the 'up' and 'down' potentiometers on the front panel.
- Unexpected Stops: Check for power fluctuations or intermittent control signals. Inspect for any fault indicators if available on the device or system.
For complex issues, contact Danfoss technical support.
