The G code command block of the canned cycle does not specify the Z point of the drilling axis. E: The input power supply is abnormal (open phase) After one minute the PSM moves into the alarm state and stops working. When executing M51, the M30 automatic power-off function cannot be executed. If you need to speak with one of our friendly and knowledgeable customer service representatives, please call (877)876-3994, and we will be happy to assist you. The nth axis (axis 18) servo amplifier READY signal (DRDY) went off. So when the PSM has a bad fan, it tells the spindle and servo amps and they all let the CNC know. 200-V control power (CX1A) is not supplied. Alternatively, in threedimensional circular interpolation mode, a code that cannot be specified is specified. The requirements for slaves needed for the set current control cycle, including the number, type, and connection method of them, are not satisfied. FANUC Alarms. 2) series SVU: The motor current is too high. For further information please visit our dedicated Fanuc Alpha Power SupplyPage.

Fanuc Alarm Code List [ Definitive Guide ] - CNCCookbook: Be A Better The main circuit power module (IPM) has detected an overload, overcurrent, or control supply voltage decrease, overcurrent, or control supply voltage decrease. 2) series SVU: IPM (intelligent power module) detected an alarm. There is excessive short-term regenerative power. Have questions about a FANUC CNC product? The input power supply of the main circuit has an imbalance. I would think anything over 4.75V would be fine. Due to an NC or servo system fault in the reference position return, there is the possibility that reference position return could not be executed correctly. Do you think this is too low? Fuses F1,F2,F3 for AC input blown out. Check cable J91 between the Input Unit and Power Supply Unit, or for a failed Input Unit. The main circuit power module (IPM) has dedected an abnormal condition. To order a replacement part or a repair job, please call 800-691-8511 or email sales@mroelectric.com. A and 10 are really the same thing, it just depends on how much room the power supply has available to show you what the alarm is - and that depends on which power supply you have.If the power supply only has a single seven-segment display, it will display an A for a bad external fan.If the power supply has two seven-segment displays, then it will display a 10 for a bad external fan.The fan is physically mounted on the top of the radiator / heatsink.The heatsink is mounted on the back of the power supply and goes through the wall that it's mounted on. The parameter setting that determines the relationship between the rotation axis and rotation plane is incorrect. The generating station is located in Delta, Utah.
