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.
Parameter warning when parameter value is outside setting range. The manual's first action is: “Set it correctly.”
Absolute position counter warning from encoder noise or faulty encoder. The manual's first action is: “Take noise suppression measures.”
Overload warning indicating possible overload alarm 1 or 2 occurrence. The manual's first action is: “Load increased to 85% or more of overload alarm 1 or 2 occurrence level. Cause, checking method Refer to 50, 51.”
Excessive regenerative warning if regenerative power exceeds brake resistor capacity or load is too high. The manual's first action is: “1. Reduce frequency of positioning. 2. Change regenerative brake option for the …
Battery warning when absolute position detection system battery voltage is reduced. The manual's first action is: “Change the battery.”
Home position setting warning from droop pulses, home return during operation, or high creep speed. The manual's first action is: “Remove the cause of droop pulse occurrence”
Open battery cable warning due to open cable or voltage below 2.8V. The manual's first action is: “Repair cable or changed.”
Watchdog indicating fault in servo amplifier parts. The manual's first action is: “Change servo amplifier.”
Serial communication error from faulty cable or communication device. The manual's first action is: “Repair or change the cable.”
Error excessive due to too small acceleration/deceleration time constant or torque limit value or power supply voltage drop. The manual's first action is: “Increase the acceleration/deceleration time constant.”
Overload 2, caused by machine striking something or wrong servo motor wiring or system instability. The manual's first action is: “Review operation pattern. Install limit switches.”
Overload 1. The manual lists no action for this code.
Servo motor overheating. The manual lists no action for this code.
Main circuit device overheating occurs when internal components exceed safe temperature thresholds. The manual lists no action for this code.
Parameter error indicates an incorrect or invalid parameter setting in the system. The manual lists no action for this code.
