<1> If blinking continues Replace the Servo Amplifier. Abnormal servo motor load has been detected. PSM: Input voltage is in the openphase condition. If you need a replacement part, please call 800-691-8511 or email [email protected]. (warning). FANUC Troubleshooting Manual - FANUC CNC FAQ - MRO Electric Blog There is excessive short-term regenerative power. In the main circuit the DC voltage at the DC link is abnormally high. Failure of System s/w EPROM's. Failure of CRT/MDI power supply - check +5 on CA3, pins 4,5,6 or CP23, pins 1,2; +24 on CD1, pin 14 or CP23, pins 5,6; d. Get when NMI occurs continually. b. When a P/S alarm occurs on the machine tool, full-time maintenance personnel must be present to deal with it. 2) series SVU: The regenerative discharge amount is too large. DC voltage of the main circuit power supply is abnormally low or the circuit breaker is tripped. If the alarms below are present with the corresponding SPM alarms then these are PSM issues! ;4) Tool center point control is provided during tool length compensation, or tool length compensation is applied during tool center point control. Then overcurrent on the power supply voltage circuit. Current exceeding the preset value has continued longer than normal. FANUC power supply repair or exchange services. A cooling fan of external cooling has stopped. Position detection system fault in the nth axis (axis 14) pulse coder (disconnection alarm). IPA's Intermountain Power Project includes a two-unit, coal-fired, steam-electric generating station, with a net capacity of 1,800 megawatts. We're here to help. This error usually occurs as the result of an improperly set parameters. For further information please visit our dedicated Fanuc Alpha I Power Supply Module Page. Control needs a software update.

Fanuc Alarm Code List [ Definitive Guide ] - CNCCookbook: Be A Better A broken wire in the builtin pulse coder was detected by hardware. A first to third reference position return cannot be executed because the reference position has not yet been established. I just replaced with after market, same specs, new fan it is working now. A06B-6083-HXXX If Alarm 51 is present on the spindle power module then PSM issue indicating: DC Bus link is low. If you want to use this amplifier, reset the function bit 2209#4 to 0. Don't attempt to perform anything discussed in this presentation if you are not both fully qualified to do so and have the equipment owner's permission to do so.Once you are done troubleshooting and before performing any maintenance, follow all plant safety and lockout procedures.
