This guide will help you diagnose the source of the alarm by explaining what each alarm code means. Check the connection. The control power supply voltage decreases. Alarm occurs when regenerative discharge resistor is disconnected. The position deviation value when the nth axis (axis 18) moves is larger than the set value. Fill out the form below and a knowledgeable FANUC automation expert will be in touch. Dealing with alarm codes is a matter of first understanding what they mean, and then deciding whats causing the code based on the codes meaning. Over current flowed into the input of the main circuit. Recently we had a customer who was working on troubleshooting a FANUC CNC Power Supply alarm that he had on a machine. Once the system has reached this point all the drives become NOT READY and the machine will not be able to move.The amplifier units tend to look alike so it's not a bad idea to access the electronics cabinet with power on (please do it safely) and look at the status displays of the units while the alarm is occurring. If Alarm 59 presents on SPM in combination with AL.2 on PSM; then cooling Fan has stopped in the PSM. If Alarm 51 is present on the spindle power module then PSM issue indicating: DC Bus link is low. Even though the nth axis (axis 18) READY signal (MCON) went off, the servo amplifier READY signal (DRDY) is still on. Turn off the power to the CNC, then remove and insert the pulse coder cable. The temperature of the regenerative resistor has arisen abnormally. Below is a list of FANUC servo amplifier alarms and faults with a short description briefly describing the source of each error code. Does anyone got any ideas for us? 1 (for PSM-5.5i to 15i) The main circuit power module detected an abnormal condition. The position deviation value when the nth axis (axis 18) moves is larger than the set value. Fanuc Alpha I Power Supply Alarms. Alarm Codes and Errors - DNC Do you think this is too low? List of Common Fanuc Alarm Codes - TIE Information Center The difference between the errors in the semiclosed loop and closed loop has become excessive during dual position feedback. Certain power supply module alarms occur that can force the spindle amplifier module to alarm in Tandem. If you need any help interpreting an error, contactTri Star CNC Services. Refer to diagnostic display 722 or 723 for details. A G code that cannot be specified is found. 2) PSMR: The spare discharge circuit of the DC link is abnormal. We're here to help. What Is CNC G Code? SP9003 SSPA:03 DC-Link Fuse is broken; SP9004 SSPA:04 Power Supply Error; SP9006 Thermal Sensor Disconnect; SP9007 SSPA:07 Over Speed; SP9009 SSPA:09 Overheat main circuit; SP9010 SSPA:10 LOW VOLT INPUT POWER; SP9011 SSPA:11 OVERVOLT POWER CIRCUIT; SP9012 SSPA:12 OVERCURRENT POWER . 2) The power to the amplifier was turned off suddenly. A06B-6120-HXXX AL-05 Control power supply fuse blown Try again from the manual reference position return. Learn how your comment data is processed. 2004, bit 0 of parameter No. 2003, and bit 0 of parameter No. Do not confuse these alarms with Fanuc CNC control system power supply unit alarms; which are a different matter altogether. Be sure to check out our article covering FANUC CNC Troubleshooting Frequently Asked Questions here. Or, when the power was turned on, DRDY went on even though MCON was off. An error was detected in the RAM write/read test at powerup. Please refer to the following alarm codes pertain to the FANUC 200VAC and 400VAC PS modules with codes PSM HV, PSM, and PSM-R (part numbers started from A06B-6077, A06B-6081, A06B-6087, A06B-6091). Diagnosis of alarm codes on the CNC machine can be an expensive time waster.
