The characteristics, usage methods, parameter settings, and wiring of ABB drive ACS510 constant pressure water supply control

The control characteristics of ABB VFD ACS510 for water supply are as follows:

  1. High control precision and good stability: It provides powerful support for the automatic control of constant pressure water supply systems by achieving precise speed regulation, reduced starting current, power saving, high reliability, and jitter control.
  2. Simple design and easy operation: It adopts a visual interface design and an easy-to-operate keyboard controller. Through the intuitive operating interface, users can easily understand the working status of the VFD and more easily guide and maintain it.
  3. High reliability and strong safety: It has multiple protection functions such as overcurrent, overvoltage, and short circuit, and reduces mechanical vibration and noise of the motor, thereby reducing the maintenance cost of the motor and the safety risks for users.
  4. Perfect matching with fans and pumps: The enhanced PFC application can control up to 7 (1+6) water pumps and switch more pumps. The SPFC cyclic soft start function can adjust each pump sequentially, with a maximum of 6 water pumps, without the need for an additional PLC.
  5. Improving the safety of the system: The constant pressure frequency conversion water supply using ABB ACS510 improves the safety of equipment operation. The water supply system, with PLCs and VFDs, has stable and efficient intelligent integrated circuits with automatic detection, leakage protection, phase failure protection, and automatic alarm functions.
  6. Improving the performance of water supply systems: In the centrifugal pump parallel operation mode of water supply, if one of the centrifugal pumps fails, the thermal relay controlling this centrifugal pump can be set to failure. At this time, the corresponding frequency control cabinet will display that this centrifugal pump has failed, the fault light will turn on, and when the frequency conversion water supply system is running, it will skip the operation of the centrifugal pump and motor with the failure, improving the performance of water supply systems.

In summary, ABB VFD ACS510 has characteristics such as high precision, good stability, simple design, high reliability, strong safety, etc., improving the performance and safety of water supply systems.

One-to-one PID configuration:

ABB VFD one-to-one wiring
The one-to-one PID configuration is typically used to control a target variable, such as temperature, pressure, or flow rate, and regulate the output of the VFD using an input signal. For the one-to-one wiring of the ABB VFD, the following steps can be followed:

Determine the required input and output signals: A control signal input (such as analog input AI or digital input DI) is typically required to receive the control signal, and an output signal (such as analog output AO or digital output DO) is used to control the output frequency of the VFD.

Connect the input signal: Attach the control signal wire to the corresponding input terminals on the VFD. If using analog input, ensure that the resistance and potentiometer on the signal wire are set correctly. If using digital input, connect the signal wire to the corresponding DI terminals.

Connect the output signal: Attach the output frequency wire from the VFD to the corresponding output terminals. If using analog output, ensure that the resistance and potentiometer on the signal wire are set correctly. If using digital output, connect the signal wire to the corresponding DO terminals.

Set the VFD parameters: Configure the VFD parameters according to the control requirements. This includes setting the target frequency, maximum and minimum frequencies, acceleration time, and deceleration time, among others.

Debug and test: After completing the wiring and parameter settings, perform testing to ensure that the system is functioning properly. Check that the input signal is correctly controlling the output of the VFD and that the system is stable and operating under various conditions.

Actual wiring instructions for a one-to-one scenario

  1. 1.For voltage output instruments, such as a remote pressure gauge (range 0-10V), connect the three wires to terminals 4, 5, and 6 according to the labeling (internal resistance requirements: 1KΩ-10KΩ). Simultaneously, move the AI2 DIP switch in jumper J1 on the terminal block to the left (as shown in the diagram above). This signal represents the actual pressure feedback value.
    If it’s a current output pressure sensor, connect the two wires to terminals 5 and 6. Simultaneously, move the AI2 DIP switch in jumper J1 on the terminal block to the right (as shown in the diagram above).
  2. 2.Short-circuit terminals 11 and 12.
  3. 3.Connecting terminals 10 and 13 provides the start signal.

Parameter Settings:

99.02 6 = PID Control Macro
This parameter sets the control macro to PID, which means the device will use Proportional-Integral-Derivative control for precise regulation.

10.02 1 = DI1 Controls Start/Stop
This setting determines that Digital Input 1 (DI1) will be used to control the starting and stopping of the process or device.

11.02 7 = External 2
This parameter is likely referring to an external control source or input selection. “External 2” could be a specific configuration for an external signal or device.

13.04 20% (When the actual signal is 4-20mA or 2-10V)
This setting configures the input signal scaling. It indicates that when the incoming signal is within the range of 4-20mA or 2-10V, it will be interpreted as 20% of the full scale value.

16.01 0 – No start permissive signal required
This parameter indicates that no external permissive signal is needed to start the device or process. It’s set to 0, which means the start permissive signal is not required.

40.10 19 (Internal setpoint)
This parameter sets the internal setpoint to 19. The exact meaning of this value depends on the context and scaling of the system, but it typically represents a target value for the controlled variable.

40.11 Set pressure value (Percentage of the pressure gauge range, e.g., if the target is 8 kg and the range is 16 kg, set it to 50%)
This parameter is used to set the desired pressure as a percentage of the pressure gauge’s total range. In the example given, the target pressure is 8 kg out of a possible 16 kg range, so it’s set to 50%.

ABB Drives ACS510 One-to-Three Wiring

1.The feedback signal from the pressure sensor is of the current type. To align with this, configure J1 for current input by dialing the code to the right.

2.Establish a short circuit between pins 11 and 12.

3.Connecting pins 10 and 13 initiates the start signal.

4.For the interlocked startup of three pumps, establish connections between pin 10 and pins 16, 17, and 18 respectively.

5.Each of the three pumps should be wired to a separate relay, ensuring individual control.

VFD Parameter Settings

Parameter Set Value

99.02 6 = PID Control Macro

10.02 1 = DI1 Controls Start/Stop

11.02 7 = External 2

13.04 20% (When the actual signal is 4-20mA or 2-10V)

14.01 31 = PFC Control

14.02 31 = PFC Control

14.03 31 = PFC Control

16.01 0 – No start permissive signal required

40.10 19 (Internal setpoint)

40.11 Set pressure value (Percentage of the pressure gauge range, e.g., if the target is 8 kg and the range is 16 kg, set it to 50%)

81.17 2 = Number of auxiliary units

81.27 3 = Number of auxiliary units

Note: There seems to be a redundancy in the parameters 14.01, 14.02, and 14.03, all set to “PFC Control” and parameters 81.17 and 81.27 both referring to “Number of auxiliary units”. Please check if these are indeed distinct parameters or if some correction is needed. Additionally, ensure that the parameter names and values align with the specific model and manual of the frequency converter being used.

ABB DRIVE ACS510 Constant Pressure Water Supply Control One to Two Scheme, Wiring and Parameter Settings

Take advantage of ABB’s ACS510 VSD for seamless multi-pump pressure control. With its advanced PFC application macro, you can effortlessly manage up to 7 pumps while ensuring consistent pressure regulation. This powerful feature eliminates the need for a separate constant pressure water supply controller, simplifying your system design. By implementing the SPFC macro, you can enjoy the added benefit of reducing stress on your pumps and power grid through gentle soft-start sequences. Consider SPFC as an enhanced version of PFC, providing superior control and reliability for your critical applications.

According to your description, DL6 is used for start commands, DL1 and DL2 for PFC control. SA1, SA2, and SA3 are three-position switches, with the middle position as stop. When manually operating at rated frequency, the switch is set to the right, and when the automatic allow signal is present, the switch is set to the left. The connections at 19, 21 and 22, 24 are connected to the relay terminals below the VFD, corresponding to the normally open contacts of RO1 (Relay 1) and RO2 (Relay 2).

The difference between PFC and SPFC:

In automatic mode with PFC: When SA2 and SA3 are set to the automatic position and the power is turned on, relay 1 on the inverter engages, which causes KM1 to engage and the motor M1 to start operating at variable frequency. If the frequency reaches the start-up frequency +1, the auxiliary motor is engaged, and relay 2 on the inverter engages, causing KM3 to engage and motor M2 to start operating at rated frequency. With PFC in automatic mode, it is possible to switch pumps at regular intervals.

In automatic mode with SPFC: When SA1 and SA2 are set to the automatic position and the power is turned on, relay 1 on the inverter engages, which causes KM1 to engage and the motor M1 to start operating at variable frequency. When the frequency reaches the start-up frequency +1, relay 1 is first disengaged and then relay 2 is engaged, causing KM4 to engage and motor M2 to start operating at variable frequency. Simultaneously, relay 1 re-engages to cause KM2 to engage and motor M1 to operate at rated frequency. With SPFC in automatic mode, it is not possible to switch pumps at regular intervals.

8127 MOTORS 2 After SPFC takes effect, it defaults to 2, and there is no need to adjust the two pumps

The parameters mentioned in this article use SPFC macros, and PFC is also similar, except that the macro parameter is 7.VSDs such as ACS550 and ACS355 should also be able to achieve constant pressure water supply frequency converter control through similar operations.

    Our skilled technicians use a hair dryer to gently heat the film adhering to the touch screen. This softens the adhesive, making it easier to peel off the outer layer without causing further damage.

    Touchpad Replacement:
    Once the old touchpad is removed, we replace it with a high-quality touchpad from our inventory. Longi Electromechanical Company has reverse-engineered various touch screen models, ensuring that our replacement parts are fully compatible with the original equipment.

    Reassembly:
    We apply double-sided tape to the touch screen border and securely attach the new touchpad. This ensures a perfect fit and optimal performance.

    Testing and Fine-Tuning:
    With the new touchpad in place, we reinstall the motherboard and LCD, then flip the unit over to test its functionality. Our rigorous testing process ensures that the touch screen operates smoothly and accurately.

    Final Assembly and Quality Check:
    After successful testing, we apply a protective film to the touch screen and reassemble the unit. A final quality check is performed to ensure that the repair meets our high standards.

    Global Servo CNC maintenance center

    Global Servo CNC maintenance center,Professional maintenance of servo CNC systems

    Remember to contact Longi Electromechanical for any issues with servo and CNC systems!

    Servo systems differ from VFDs in that they offer higher precision and typically come with delicate encoders. Servo motors are synchronous motors with magnets inside, and if not handled carefully during disassembly and assembly, their original performance may not be restored. Additionally, different servo drivers cannot be used interchangeably with other servo motors. This means that during the repair of a servo driver, a corresponding servo motor and cable plug are required for proper testing. Similarly, repairing a servo motor also requires a matching servo driver for testing, which can pose challenges for many maintenance personnel.

    As for CNC (Computer Numerical Control) systems, most are embedded industrial computer types with closed control systems. Each manufacturer has its own design ideas, programming methods, wiring, and communication architectures, making them incompatible with one another.

    Longi Electromechanical Company has designed various styles of servo and CNC maintenance test benches to test the working conditions of different CNC systems, servo drivers, or servo motors. When servo systems encounter issues such as no display, phase loss, overvoltage, undervoltage, overcurrent, grounding, overload, module explosion, magnet loss, parameter errors, encoder failures, communication alarms, etc., the corresponding platform can be used to test and diagnose the problem.

    Repair Hotline: +8618028667265 Mr. Guo

    After resolving these issues, the servo system also needs to undergo a simulated load test to avoid problems such as overcurrent under load conditions, even if it performs well under no-load conditions. This ensures that the servo system is fully functional and ready for use in actual applications.

    For the CNC system, it is also necessary to conduct simulated operation before normal delivery to avoid any discrepancy with the on-site parameters. Currently, Rongji Electromechanical possesses hundreds of servo and CNC test benches, which can quickly identify problem areas and promptly resolve issues. With these advanced testing facilities, Longi Electromechanical ensures the smooth operation and reliability of the repaired equipment.

    The Servo and CNC Repair Center established by Longi Company currently has over 20 skilled and experienced maintenance engineers who specialize in providing repair services for different brands and specifications of servo and CNC systems. They implement tailored repair solutions for different maintenance projects, ensuring efficient and high-quality service for customers.

    Longi Electromechanical Company specializes in the maintenance of VFDs and strictly requires its engineers to followlow standard operating procedures. Upon receiving a unit, the engineers carefully inspect its exterior and clarify any fault conditions with the customer before beginning work. Any removed circuit boards are cleaned using ultrasonic cleaning equipment. Repaired circuit boards are coated with high-temperature and high-pressure-resistant insulating paint, dried in a drying machine, and then reinstalled in the VFD, with measures taken to prevent corrosion and interference.

    The repaired VFD will undergo a simulated operation with load using a heavy-load test bench to avoid any potential issues that may arise under actual load conditions on site.

    When it comes to VFD maintenance, most cases are related to the equipment on site. Sometimes a standalone unit may have been repaired, but it doesn’t work properly when installed on site. In some cases, the problem lies with the system rather than the VFD itself. For such issues, if the customer requests on-site service, we will do our utmost to resolve the problem for them. If the location is far away, such as in another province, we can use tools like video conferencing and phone calls to allow our engineers to remotely diagnose and resolve the on-site issues for the customer.
