FANUC SV5137 FSSB Alarm: Causes and Troubleshooting Guide
The FANUC SV5137 FSSB alarm indicates an FSSB configuration error. This commonly occurs when the connected servo amplifier type or servo axis configuration does not match the FSSB settings in the CNC system. In simple terms, the CNC system has detected a mismatch between the actual servo amplifier connected through the FSSB line and the amplifier or axis configuration registered in the system. If SV5137 appears together with SV5136, SV1067, or other servo/FSSB alarms, troubleshoot those related alarms first. SV5137 may be a secondary alarm caused by communication, amplifier power, or...

FANUC SV5136 Alarm: FSSB Insufficient Amplifier Number Troubleshooting
FANUC SV5136 alarm means the number of amplifiers recognized by FSSB is less than the number of controlled axes. This usually happens because the axis setting is incorrect, the servo amplifier connection is abnormal, the control power is unstable, the fiber optic cable connection is wrong, or the FSSB compatibility parameter such as 14476 is not set correctly. Before replacing the CNC controller axis card or main board, first check the actual FSSB connection status, servo amplifier power supply, wiring condition, fiber optic connection, amplifier model compatibility, and FSSB-related parameters. What... Maggiori informazioni...
FANUC SV5134 Alarm: FSSB Startup Timeout Troubleshooting
FANUC SV5134 alarm means FSSB did not become ready during startup initialization. The key checks are the FSSB-related parameter settings, P10339#1 when using certain 0i-D system configurations with spindle optical cable connection amplifiers, diagnosis data 3510 / 3511 / 3513, servo amplifier DC24V control voltage, FSSB fiber optic cable connection, fiber ports, and finally the CNC axis card or main board. Before replacing the NC controller axis card or main board, first confirm whether the FSSB connection parameters, servo amplifier control voltage, and fiber optic connection are normal. SV5134 is often... Maggiori informazioni...
FANUC SV1067 Alarm: FSSB Configuration Error Software Troubleshooting
FANUC SV1067 alarm usually means the actual servo amplifier hardware connection does not match the FSSB parameter configuration. The key checks are the amplifier connection status, parameter P1902, servo axis number settings P987/P988, servo axis valid setting P11802#4, FSSB automatic or manual setting, and amplifier/system compatibility. This alarm is often caused by a mismatch between the connected servo amplifier type and the FSSB setting value. Before replacing hardware, first use the FSSB setting screen to confirm which amplifier is recognized and which amplifier or axis is abnormal. What Does FANUC SV1067... Maggiori informazioni...
FANUC SV1026 Alarm: Illegal Axis Assignment and FSSB Parameter 1023 Troubleshooting
FANUC SV1026 alarm usually means the servo axis assignment parameter is not set correctly. The most important item to check is parameter 1023. Make sure it does not contain negative values, duplicate values, or values larger than the number of controlled axes. After correcting the parameter, reinitialize the FSSB setting. This alarm is commonly related to incorrect servo axis number assignment, parameter loss, wrong axis configuration, or an incomplete FSSB initialization after changing servo-related parameters. What Does FANUC SV1026 Alarm Mean? FANUC SV1026 means illegal axis assignment. The CNC system has... Maggiori informazioni...
FANUC SP9010 Alarm 10: Input Power Voltage Low Troubleshooting
FANUC SP9010 alarm 10 means the spindle amplifier has detected low input power voltage. The main checks are the amplifier input power voltage, input power cable, CXA2A-CXA2B jumper cable, DC24V output from the common power supply module, and finally the spindle amplifier. Do not replace the spindle amplifier immediately. First confirm whether the voltage supplied to the spindle amplifier is normal and stable. If the DC24V supply is low, check the common power supply input voltage and the common power supply module before replacing the spindle amplifier. What Does FANUC SP9010... Maggiori informazioni...
FANUC SP9009 Alarm 09: Main Circuit Overheat and Spindle Amplifier Heat Sink Fault
FANUC SP9009 alarm 09 means the spindle amplifier main circuit temperature is too high. The alarm is usually caused by poor heat sink cooling, dirty cabinet filters, blocked airflow, external cooling fan failure, high ambient temperature, heavy cutting load, frequent spindle acceleration/deceleration, poor control board contact, or spindle amplifier failure. Before replacing the spindle amplifier, first check the cooling condition of the control cabinet, heat sink airflow, external cooling fan, air inlet filter, cutting load, and whether the alarm appears during cutting, light load, or immediately after power-on. What Does FANUC... Maggiori informazioni...
FANUC SP9007 Alarm 07: Spindle Motor Overspeed Troubleshooting
FANUC SP9007 alarm 07 usually means the spindle motor speed has exceeded about 115% of the maximum speed. The main checks are spindle motor parameters, spindle motor initialization, power line phase sequence, spindle detector, ladder logic during spindle synchronization, and finally the spindle amplifier. For this alarm, do not replace the spindle amplifier first. Start by checking the spindle motor model, motor code, parameter setting, and power line phase sequence. SP9007 is often related to incorrect motor parameters, wrong phase sequence, abnormal spindle detector feedback, or spindle synchronization control issues.... Maggiori informazioni...
FANUC SP9006 Alarm 06: Thermal Relay Disconnection and Spindle Motor Temperature Sensor Fault
FANUC SP9006 alarm 06 usually means the spindle motor temperature sensor circuit is abnormal or disconnected. The most common checks are spindle motor parameters, spindle feedback cable, motor thermistor resistance, motor insulation, ambient temperature, and finally the spindle amplifier. For this alarm, do not replace the spindle amplifier first. Start from the spindle motor parameters and feedback cable. In many cases, SP9006 is caused by incorrect motor parameter setting, damaged feedback cable, abnormal thermistor, or a temperature sensor wire disconnection. What Does FANUC SP9006 Alarm 06 Mean? FANUC SP9006 is... Maggiori informazioni...
FANUC SP9004 Alarm: Power Phase Loss or Fuse Blown
The FANUC SP9004 alarm indicates a power phase loss or fuse blown alarm. The related amplifier alarm number is 04. This alarm occurs when the system detects an abnormal condition in the common power supply input, such as phase loss, abnormal power frequency, or unbalanced input power. In a FANUC spindle drive system, the common power supply must receive stable and balanced input power. If one phase is missing, the input voltage is unstable, the main power terminal is loose, the MCC contactor does not work correctly, or the power... Maggiori informazioni...
FANUC SP9003 Alarm: DC Link Fuse Blown in Spindle Amplifier
The FANUC SP9003 alarm indicates a DC link fuse blown alarm inside the spindle amplifier. The related amplifier alarm number is 03. This alarm occurs when the fuse in the DC link section of the spindle amplifier is blown or when the DC link voltage becomes insufficient due to a hardware fault. The DC link section is an important power circuit inside the spindle drive system. If the DC link fuse is blown, the spindle amplifier cannot maintain the required DC bus voltage. The CNC system may detect this condition... Maggiori informazioni...
FANUC SP9002 Alarm: Excessive Spindle Speed Deviation
The FANUC SP9002 alarm indicates an excessive spindle speed deviation. The related amplifier alarm number is 02. This alarm occurs when the detected spindle motor speed cannot follow the commanded spindle speed. In normal operation, the spindle motor feedback speed should closely follow the spindle command speed. If the detected speed is far away from the command speed, the CNC system may judge that the spindle cannot accelerate, decelerate, or rotate as required, and then generate the SP9002 alarm. SP9002 may be caused by excessive cutting load, unreasonable acceleration/deceleration time... Maggiori informazioni...
