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.
Transfer error happens during data transfer between components or systems. The manual lists no action for this code.
Command frequency error occurs when the command frequency is outside acceptable parameters. The manual lists no action for this code.
CRC error indicates a checksum verification failure in data transmission. The manual lists no action for this code.
Overvoltage occurs when voltage exceeds safe limits. The manual lists no action for this code.
Overcurrent occurs when excessive current is flowing through the system. The manual lists no action for this code.
Overspeed indicates the motor has exceeded its maximum allowable speed. The manual lists no action for this code.
Regenerative error happens when regenerative power exceeds limits due to mismatched settings or unconnected options. The manual's first action is: “Set correctly.”
Absolute position erase occurs when absolute position data is corrupted or during first power-on of the system, requiring battery replacement. The manual's first action is: “Change battery.”
Main circuit error indicates a ground fault at the servo motor outputs due to wiring contact or deteriorated cable sheaths. The manual's first action is: “Change the cable.”
Encoder error 2 occurs from communication issues between the encoder and servo amplifier, or if the encoder is faulty or disconnected. The manual's first action is: “Connect correctly.”
Motor combination error happens when an incorrect combination of servo amplifier and motor is used. The manual's first action is: “Use correct combination.”
Memory error 3 occurs due to a ROM memory fault. The manual lists no action for this code.
Board error indicates faulty parts within the servo amplifier itself. The manual's first action is: “Change the servo amplifier.”
Encoder error 1 happens when there's a communication issue between the encoder and servo amplifier, or if the encoder is faulty or its cable is damaged. The manual's first action is: “1. CN2 connector disconnected. Co…
Memory error 2 occurs due to an EEP-ROM fault. The manual's first action is: “Change the servo amplifier.”
