Appendix
(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
630 Updating system code error (Application detection) The updating system code is invalid. 631 Updating unit code error (Application detection) The updating unit code is invalid. 632 Updating device number error (Application detection) The updating device number is invalid. 633 Feedback pulse synchronization error (Detected in the speed
loop)
Abnormal feedback pulse synchronization (detected in the speed loop).
634 Feedback pulse synchronization error (Detected in the position
loop)
Abnormal feedback pulse synchronization (detected in the position loop).
635 Deadman/enable switch requiring reset recovery open Reset the deadman/enable switch, and then reconnect the power. 636 Serial encoder command busy error The system was busy when the serial encoder command was issued. 637 Serial encoder command timeout error Completion of the serial encoder command cannot be confirmed after the specified
time.
638 Speed control parameter setting command busy error The system was busy when the speed control parameter setting command was
issued.
639 Speed control parameter setting command timeout error Completion of the speed control parameter setting command cannot be confirmed
after the specified time.
63A ABZ encoder logic error An encoder phase-A/B electrical level pattern error was detected. The power must be
reconnected.
63B Encoder/motor control constant table flash ROM status error Data is not written correctly to the flash ROM, or the data is of an old, incompatible
version.
63C Encoder/motor control constant table checksum error The flash ROM data is corrupted. 63D ABZ encoder specification error An ABZ encoder cannot be installed for this axis. Check the “motor/encoder
configuration information” in driver parameter No. 26 and encoder parameter No. 11.
63E ABZ encoder magnetic-pole sensor signal logic error Check if the encoder cable is connected.
63F Encoder control constant error The encoder control constant is invalid.
640 Motor control constant error The motor control constant is invalid. 641 Encoder power-source voltage control parameter error Check driver parameter Nos. 32, 33, etc. 642 Speed loop parameter error Check driver parameter Nos. 43, 44, 45, etc. 643 Encoder resolution division error Check “Axis-specific parameter No. 43: Encoder division ratio.” 644 Encoder/motor combination mismatch error (encoder
resolution)
Check driver parameter No. 26, encoder parameter No. 11.
645 DAC transfer completion check timeout error when encoder
power was supplied
A timeout occurred during DAC transfer when the encoder power was supplied.
646 Encoder EEPROM read busy error The encoder is faulty or an encoder communication failure occurred. 647 Encoder EEPROM write address mismatch error The encoder is faulty or an encoder communication failure occurred. 648 Encoder EEPROM read address mismatch error The encoder is faulty or an encoder communication failure occurred. 649 Undefined serial encoder installation error Installation of serial encoder is not defined. Check the “motor/encoder configuration
information” in driver parameter No. 26 and encoder parameter No. 11.
64A Undefined serial encoder command error The serial encoder command is not defined.
