I. Achieving Constant Pressure Water Supply with Single Pump Control

In single pump control mode, the PDG10 series SANJ INVERTER automatically adjusts the speed of the water pump motor by setting the pipe network pressure value, thereby maintaining a constant water supply pressure. Below are the steps to achieve constant pressure water supply:

1. Wiring

  • Main Circuit Wiring: Connect the three-phase power supply to the R, S, T terminals of the inverter and the motor to the U, V, W terminals, ensuring the grounding terminal is reliably grounded.
  • Control Circuit Wiring: Depending on requirements, connect the pressure sensor to the AI1 or AI2 terminal and set the F2.00 or F2.02 parameter according to the sensor type. If using external start/stop control, connect the start and stop signals to the DI1 and DI2 terminals.

2. Parameter Settings

  • Pressure Setting: Set the target pressure value through the F0.00 parameter. For example, to achieve a pipe network pressure of 3.0 kg, set F0.00=3.0.
  • Start Mode: If using external start/stop control, set F0.05=1 (terminal start/stop).
  • Sensor Settings: Set F0.08 (sensor range), F0.09 (sensor feedback channel selection), and F2.00 or F2.02 (sensor feedback type selection) according to the pressure sensor type.

Understanding and Solving A5001 Alarm Fault in ABB ACS510/ACS550/ACH550 Series Drives

When using ABB’s ACS510, ACS550, and ACH550 series of Drives, users may encounter the “A5001” alarm fault. This fault typically indicates that there is no response from the drive, meaning the operator panel is unable to read information from the main board despite being powered on and displaying. This article will provide a detailed analysis of the A5001 alarm fault based on ABB’s ACS510 manual and practical experience, along with targeted solutions.

ACS510 generates A5001 alarm

I. Overview of A5001 Alarm Fault

When the ABB ACS510/ACS550/ACH550 series of drives displays the “A5001” alarm, the operator panel usually shows this error code, and pressing any button has no effect. According to the ABB manual, the A5001 alarm represents “No Response from Drive,” indicating that although the operator panel is powered on and displaying, it is unable to communicate with the main board.

II. Analysis of Fault Causes

1. Operator Panel Failure

The operator panel itself may have issues, such as damage to the communication interface with the main board. In this case, even though the operator panel is powered on and displaying, it cannot exchange data with the main board.

2. Connection Cable Issues

The connection cable between the operator panel and the main board uses a network cable format. If the connectors on the cable are not properly seated or the cable is internally damaged, communication will be interrupted.

3. Main Board Failure

Main board failures are also a common cause of the A5001 alarm. Damage to the CPU chip or other key components on the main board will prevent it from functioning normally, thereby disrupting communication with the operator panel.

4. Fan Failure

If the fan is damaged or not rotating, it may affect the operating voltage of the main board, causing it to malfunction. While this scenario is less common, it still needs to be considered.

5. Power Board Issues

Although less frequently encountered in practice, abnormal power supply from the power board can also trigger the A5001 alarm. In such cases, the 10VDC and 24VDC voltages on the power board can be measured to confirm its functionality.

Internal diagram of ABB VFD

III. Fault Solutions

1. Replace the Operator Panel

If the operator panel itself is suspected to be the problem, a spare operator panel can be tried. Before replacement, ensure that the new panel is compatible with the inverter model.

2. Check and Replace the Connection Cable

Inspect the connection cable between the operator panel and the main board for any damage. If the cable is damaged or the connectors are not properly seated, replace the cable or remake the connectors. To rule out cable issues, the operator panel can be directly connected to the main board’s socket for testing.

3. Replace the Main Board

If it is confirmed that the main board is faulty, it needs to be replaced. Before replacing the main board, back up the parameter settings on the original board and reconfigure them on the new board to ensure the inverter functions normally.

4. Check and Replace the Fan

If fan failure is suspected, temporarily disconnect the fan’s working plug and conduct a power-on test. If the fault disappears after removing the fan, it indicates that the fan is indeed defective and needs to be replaced.

5. Check the Power Board

Although less common, power board issues cannot be ruled out. The 10VDC and 24VDC voltages on the power board can be measured to confirm its normal operation. If abnormal voltages are detected, further inspection of the power board or contact with professional maintenance personnel is recommended.

IV. Conclusion

When encountering the A5001 alarm fault in ABB’s ACS510/ACS550/ACH550 series of drives, users should first preliminarily diagnose the fault cause based on the fault symptoms and manual content. Then, they can follow the solutions provided in this article to troubleshoot and resolve the issue step by step. During troubleshooting, safety precautions should be taken to avoid further damage to the inverter.
