( hardly ever used it in the shop always used the hass vf3's instead ) It has been sitting for 6 months since I retired and sold off my shop. I saved this sweet little machine for my hobbies. I needed to make some parts for my street rod and fired up the http://www.practicalmachinist.com/vb/cnc-machining/fanuc-error-codes-help-123226/ fanuc. To my suprise it gives me 2 error codes; 400 servo overload 426 y axis disconnect This is what i've done so far. 1) had y axis servo ( 3 phase AC ) rebuilt per fanuc service tech. 2) replaced 1\4 axis servo drive card ( 2200.00 from fanuc ) per useless fanuc service tech. 3) checked all fuses and plugs, reseated all boards because it was moved into my garage since i sold my shop and building. 4)checked voltage coming into machine, it was 118v to 120v on all 3 legs ( 240 across phases )The multi tap transformer is set at 240v. I still have the same errors.... by the way i rang out both cables coming and going to the servo. the one thing i did just notice is that there are 6 leds on the mother board, 3 on the bottom and 3 on the top of the first 3 the two rows are both marked L1,L2,L3 i assume line numbers. the bottom 3 are off but the top 3 ( L2 is red. ) HELP PLEASE its driving me crazy. i would have a tech come fix it if there was any in my area. any ideas wo
comments Most common alarm codes found by Repair Zone technicians during repair. When your CNC machine suddenly stops working what is the first thing that you do? Probably open the cabinet and check the controller or amplifier? http://blog.repairzone.com/most-common-alarm-codes-for-fanuc-servo-amplifiers-indicated-on-the-status-display/ If your machine is equipped with Fanuc Automation components, you probably check the status display on your Fanuc servo amplifier and see a number displayed? These numbers are called alarm codes, or error codes. There could be 9 possibilities. The drive and amplifier technicians at Repair Zone use these alarm codes, also called fault codes, to help them troubleshoot during a repair. When repairing Fanuc amplifiers, many times our technicians see the same error codes fault codes come up. Here is a list of the most common Alarm codes found on the status display on C-Series, Fanuc servo amplifiers: Alarm Code #1 Overvoltage alarm (HV). If DC voltage of main power supply is abnormally high, overvoltage alarms occurs (HV level: 430V DC). Alarm occurs when regenerative discharge resistor is disconnected. For 200V AC input, main circuit voltage is 283V DC (200 x 1.414). Discharge operation is started at voltage fanuc error codes of main circuit voltage plus 60V. Alarm Code #3 DC link undervoltage alarm (LVDC). Alarm occurs if DC voltage of main circuit power supply is abnormally low (LVDV level: 120V). *Causes may include power supply voltage (+15V) being 10Vor lower and driver module PCB not inserted normally. Alarm Code #8 Overcurrent alarm (HCL). Alarm occurs when abnormally high current flows in main circuit of 1-axis amplifier or in main circuit of L axis of 2-axis amplifier. *Causes may include faulty IC, abnormal PWM signal, faulty motor, and grounded wiring. Alarm Code #2 Control power supply undervoltage alarm (LV5V). Alarm occurs if control circuit power supply voltage (+5V) is abnormally low (LV5V level: 4.6VDC). Alarm Code #5 Excessive regenerative discharge alarm (DCOH). Alarm occurs when average regenerative discharge energy is too high. *Causes may include operation of thermostat for regenerative discharge resistor or thermostat between (15) and (16) on terminal block T1; this operation results from too frequent acceleration/deceleration operations.
