Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
ABS time-out warning occurs if the PC ladder program is wrong or reverse rotation start (ST2) with improper limiting torque (TLC) wiring. The manual's first action is: “Power OFF→ON”
Absolute position counter warning occurs due to encoder noise, encoder fault, or movement exceeding ±32768 rotations from home position. The manual's first action is: “Power OFF→ON”
Overload warning occurs if overload alarm 1 or 2 may happen. The manual's first action is: “Power OFF→ON”
Excessive regenerative warning occurs if regenerative power may exceed the built-in brake resistor or option's capacity. The manual's first action is: “Power OFF→ON”
Battery warning occurs when the absolute position detection system’s battery voltage is reduced. The manual's first action is: “Power OFF→ON”
Open battery cable warning occurs due to droop pulses exceeding in-position range, command pulse entered after clearing droop pulses, or creep speed being too high. The manual's first action is: “Power OFF→ON”
Watchdog occurs when the battery cable is open or the encoder detects battery voltage dropping below 3.2V. The manual's first action is: “Power OFF→ON”
This code indicates parameter No. 1 data is faulty. The manual lists no action for this code.
This code indicates there is no fifth past alarm. The manual lists no action for this code.
This code indicates that the fourth past alarm was overspeed (AL.31). The manual lists no action for this code.
This code indicates that the third past alarm was undervoltage (AL.10). The manual lists no action for this code.
Absolute position erase occurs due to reduced super capacitor voltage in the encoder, low battery voltage, or a faulty battery cable or battery. The manual's first action is: “Power OFF→ON”
Encoder error 2 happens when the encoder connector is disconnected, the encoder cable is broken or shorted, or the encoder is faulty. The manual's first action is: “Power OFF→ON”
Monitor combination error occurs when an incorrect servo amplifier and motor combination is connected. The manual's first action is: “Power OFF→ON”
Encoder error 1 happens when the encoder connector is disconnected, the encoder itself is faulty, or the cable is damaged. The manual's first action is: “Power OFF→ON”
