Error No. Error name Description, action, etc.
667 Invalid driver initialization communication line specification error
at specification of valid axis
Initialization communication line channel number is not specified for a valid axis. Check all-axis parameter No. 1, “Valid axis pattern,” Nos. 101 and 102, “Driver/encoder communication line channel setting” and Nos. 103 and 104, “Driver initialization communication type setting.”
668 Driver target information initialization error The initialization sequence of driver target information did not complete successfully.
Check the installed driver board. Check all-axis parameter Nos. 101, 102, 103 and 104, or driver parameter No. 26, encoder parameter No. 11.
669 Encoder target information initialization error The initialization sequence of encoder target information did not complete
successfully. Check the installed encoder. Check all-axis parameter Nos. 101, 102, 103 and 104, or driver parameter No. 26, encoder parameter No. 11.
66A Power-system target information initialization error The initialization sequence of power-system target information did not complete
successfully. Check the installed power-supply board. Check the power-supply board parameters.
66B Slave communication error response error An error response was received during slave communication.
66C SCI LRC error (slave communication) The message LRC of slave communication is invalid. 66D Slave communication target ID error The target ID of slave communication is invalid.
66E Slave communication block number error The block number of slave communication is invalid.
66F Target specification error due to no axis number The specified target of slave communication (driver or encoder) is invalid (no axis
number is assigned for the target ID, or an internal driver board axis is specified).
670 Target board type error The target board type is invalid. 671 Encoder control data error The encoder control data is invalid or cannot be acquired. Take the same actions
specified for error Nos. 65A, 65B and 669.
672 Motor control data error The motor control data is invalid or cannot be acquired. Take the same actions as
specified for error Nos. 65C, 65D, 668 and 669.
673 Tracking-encoder axis specification error The specified tracking encoder axis is invalid. Check if the axis set in all-axis
parameter No. 61 can be used as a tracking encoder axis.
674 Tracking encoder open error The tracking encoder cable is open. Reconnect the power. 675 Tracking absolute encoder logic error An abnormal power level pattern was detected for the tracking encoder phase A/B.
Reconnect the power.
676 ABZ encoder magnetic-pole sensor signal read error Check if the encoder cable is connected. 677 ABZ encoder phase Z clear position error Check if the encoder cable is connected.
6A0 UBM flash ROM status error The user-data backup memory was not properly written to the flash ROM, or the
data was written in an incompatible old version.
