Hi everyone,

fbE: The message "fbE: PID feedback signal error" indicates that there is an issue with the PID (Proportional-Integral-Derivative) feedback signal being transmitted between the system and the feedback sensor. This error can impact the accuracy and stability of the system's control loop, leading to incorrect readings or unexpected behavior.

To resolve this issue, you should follow the steps listed:

    Check the parameter settings (Pr.10.01) and the AVI/ACI wiring to ensure that they are properly configured and connected. The parameter settings can influence the behavior of the feedback signal, and incorrect settings can cause issues with the feedback signal.

    Check for a possible fault between the system response time and the PID feedback signal detection time (Pr.10.08). If the response time of the system is too slow, the feedback signal may not be detected correctly, leading to inaccuracies in the control loop.

It is important to resolve this issue promptly, as an incorrect or unstable PID feedback signal can negatively impact the performance and reliability of the system. If you are unable to resolve the issue, you may need to seek assistance from a professional who is familiar with the system.

PHL: Phase Loss
The message "PHL: Phase Loss" indicates that one of the phases of the input power supply is missing or not present. This can cause the device to stop functioning or work improperly, leading to incorrect readings or unexpected behavior.

To resolve this issue, you should check the input phase wiring for loose contacts. Make sure that all of the connections are tight and not corroded. Check the wiring for any signs of damage, such as cuts or fraying.

If the wiring appears to be in good condition, you may need to check other components of the system, such as the power supply or the electrical panels. If you are unable to resolve the issue, you may need to seek assistance from a professional who is familiar with the system.

It is important to resolve this issue promptly, as a phase loss can negatively impact the performance and reliability of the system. If the issue is not resolved, it can cause the device to stop functioning, leading to costly downtime and repairs.

AUE: Auto Tuning Error.
The message "AUE: Auto Tuning Error" indicates that there has been an issue during the auto-tuning process of the drive and the motor. Auto-tuning is a process where the drive automatically adjusts its parameters to optimize the performance of the motor.

To resolve this issue, you should follow the steps listed:

    Check the cabling between the drive and the motor to ensure that it is properly connected and secured. Verify that the connections are tight and not corroded. Check the wiring for any signs of damage, such as cuts or fraying.

    Retry the auto-tuning process again. If the issue persists, it may be due to incorrect parameter settings or a problem with the motor.

It is important to resolve this issue promptly, as incorrect auto-tuning can negatively impact the performance and reliability of the motor and drive system. If you are unable to resolve the issue, you may need to seek assistance from a professional who is familiar with the system.

CP10:  Communication time-out
The message "CP10: Communication time-out error on the control board or power board" indicates that there has been a communication failure between the control board and the power board of the device. This can cause the device to stop functioning or work improperly, leading to incorrect readings or unexpected behavior.

To resolve this issue, you should follow the steps listed:

    Press the RESET key to set all parameters to their factory setting. This can help to clear any communication issues that may have caused the time-out error.

    If the issue persists after pressing the RESET key, you may need to return the device to the factory for repair. This may involve replacing the control board or power board, or making other repairs to the device.

It is important to resolve this issue promptly, as a communication failure between the control board and power board can negatively impact the performance and reliability of the device. If the issue is not resolved, it can cause the device to stop functioning, leading to costly downtime and repairs.

Ptc1, PTC2 : Motor overheat protection
The message "PTC1: Motor overheat protection" indicates that the motor has exceeded its safe operating temperature and has shut down as a result of built-in overheat protection. This can occur due to a variety of factors, including high ambient temperature, high loads, or incorrect parameter settings.

To resolve this issue, you should follow the steps listed:

    Check if the motor is overheat by touching it or using a thermometer. If the motor is hot to the touch or the thermometer readings indicate high temperatures, you should allow the motor to cool before proceeding.

    Check the settings for Pr.07.12 to Pr.07.17, which relate to the overheat protection settings. Ensure that these settings are correctly configured for the specific motor and application.

If the issue persists, other factors may be contributing to the motor overheating, such as a clogged air filter, insufficient ventilation, or an issue with the power supply. You may need to seek assistance from a professional who is familiar with the system to resolve the issue.

It is important to resolve this issue promptly, as continued overheating of the motor can lead to permanent damage and costly repairs. It can also be a safety concern, as overheated motors can pose a fire hazard.

PGEr: PG signal error
The message "PGEr: PG signal error" indicates that there is an issue with the PG (pulse generator) signal, which is used to control the speed or position of the motor. This error can be caused by a variety of factors, including incorrect wiring, a damaged PG card, or a problem with the motor.

To resolve this issue, you should follow the steps listed:

    Check the wiring of the PG card to ensure that it is properly connected and secured. Verify that the connections are tight and not corroded. Check the wiring for any signs of damage, such as cuts or fraying.

    If the issue persists after checking the wiring, try using another PG card. This will help to determine if the problem is with the PG card or another component of the system.

It is important to resolve this issue promptly, as incorrect PG signals can negatively impact the performance and reliability of the motor and drive system. If you are unable to resolve the issue, you may need to seek assistance from a professional who is familiar with the system.

CGUd: CANopen Guarding Time out
The message "CGUd: CANopen Guarding Time out" indicates that there is a problem with the CANopen communication protocol used in some variable frequency drives (VFDs). This error message specifically refers to the "guarding" time-out, which is a safety feature that monitors the communication between devices on the CAN bus to ensure that they are functioning correctly.

To resolve this issue, you should follow the steps listed:

    Connect to the CAN bus again. This may involve checking the physical connections and ensuring that the devices are properly powered and communicating with each other.

    Reset the CAN bus. This can be done by power cycling the devices connected to the bus or by using a reset command specific to the CAN bus system.

It is important to resolve this issue promptly, as a CANopen communication failure can negatively impact the performance and reliability of the VFD and the devices connected to it. If the issue is not resolved, it may cause the devices to stop functioning or work improperly, leading to incorrect readings or unexpected behavior.

deb: The message "deb: Deceleration Error" indicates that there was an unexpected power loss during the deceleration of the motor. This error occurs when the parameter Pr.08-24 is set to a value other than 0 and there is a momentary power loss.

To resolve this issue, you should follow the steps listed:

    Set Pr.08-24 to 0. This parameter determines the deceleration time of the motor and setting it to 0 will disable the deceleration function.

    Check if the input power is stable. Ensure that the power supply to the drive is stable and not fluctuating. A momentary power loss could cause the "deb" error to occur.

It is important to resolve this issue promptly, as a momentary power loss during the deceleration of the motor could cause unexpected behavior, including damage to the motor or the drive. If you are unable to resolve the issue, you may need to seek assistance from a professional who is familiar with the system.
 
ACL: The message "acL: Abnormal Communication Loop" indicates that there is a problem with the communication between the drive and the control system. This error message suggests that there is a communication loop that is not functioning correctly.
