Er.101 - Abnormality in Parameters H02 and Above (details >>)

Causes:

    After a software update, the number of function codes might change.
    This error can occur when the actual values of group parameters H02 and above exceed their limits. This usually happens during software updates.

Troubleshooting and Solutions:

    Control power voltage drops momentarily:
- Troubleshooting Method: Check whether control power circuits like L1C and L2C have been interrupted or if there was a momentary power interruption. Also, measure if the control power voltage is within specified limits.
- For 220 VAC drives: Valid voltage: 220-240V with a 10% margin (198-264V)
- For 380 VAC drives: Valid voltage: 380-480V with a 10% margin (342-528V)
- Solution: Increase power capacity or use a larger power supply. Additionally, you may need to reset to default settings (H02-31 = 1) and rewrite the parameters.

    Momentary power interruption occurs during parameter writing:
- Troubleshooting Method: Check for any momentary power interruptions during parameter storage.
- Solution: Restart the system, reset to default settings (H02-31 = 1), and rewrite the parameters.

    The limit of parameter writing occurrences is exceeded within a certain period:
- Troubleshooting Method: Check if parameter updates are frequently performed from the main control unit.
- Solution: Change the parameter writing method and rewrite the parameters. If the servo drive has a fault, the servo drive may need to be replaced.

    Software has been updated:
- Troubleshooting Method: Check if the software has been updated.
- Solution: Reconfigure the servo drive model and motor model, then reset to default settings (H02-31 = 1).

    Faulty servo drive:
- Troubleshooting Method: After turning the servo drive on and off several times, restore the default settings. If the fault persists, the servo drive may be faulty.
- Solution: Replace the servo drive.

Er.102 - Programmable Logic Configuration Error (details >>)

Causes:

    FPGA and MCU software versions might be incompatible:
- If the software versions of FPGA and MCU do not match, this error can occur. The most significant bits of the version numbers need to match to avoid this error.

    There may be a hardware fault in FPGA or MCU:
- Hardware faults can cause communication issues between the MCU and FPGA, leading to this error.

Troubleshooting and Solutions:

    FPGA software version is incompatible with MCU software version:
- Troubleshooting Method: Use the operating panel or Inovance servo commissioning software to check the MCU software version (H1-00) and the FPGA software version (H1-01). Verify that the most significant non-zero bits of the version numbers are consistent.
- Solution: If there is a mismatch, contact Inovance technical support to update the compatible FPGA or MCU software.

    Fault in FPGA hardware:
- Troubleshooting Method: If the error persists after turning the servo drive on and off multiple times, there may be a fault in the FPGA hardware.
- Solution: In this case, the servo drive will need to be replaced.

Summary: This error usually arises from incompatibility between FPGA and MCU software versions, and updating to a compatible version resolves the issue. If there is a hardware fault, replacing the servo drive is the only solution.
