Reasons and Solutions for Servo Drive Reporting Fault Code FU102
Release time:2025-06-17
Fault Code: FU102
Fault Description: Programmable Logic Configuration Error
Possible Causes and Solutions:
1. FPGA and MCU software version mismatch:
Check the MCU software version (parameter P01-00) and FPGA software version (parameter P01-01) via the drive panel or debugging software.
Verify whether the highest non-zero digits of both version numbers are consistent.
Solution: Contact our technical support to update the FPGA or MCU software to compatible versions.
2. FPGA hardware failure:
If the fault persists after multiple power cycles, replace the servo drive.
Note: This fault typically occurs due to version conflicts between core processing units. Ensure software versions match before replacing hardware.
