During simple synchronous control, the difference between the torque commands for the master and slave axes exceeded the value set in parameter No. 2031.

This alarm occurs when the n-th axis (axis 1-8) is in one of the conditions listed below. (Digital servo system alarm) 1) The value set in Parameter No. 2020 (motor form) is out of the specified limit. 2) A proper value (111 or -111) is not set in parameter No.2022 (motor revolution direction). 3) Illegal data (a value below 0, etc.) - No. 2023 (number of speed feedback pulses per motor revolution). 4) Illegal data (a value below 0, etc.) - No. 2024 (number of position feedback pulses per motor revolution). 5) Parameters No. 2084 and No. 2085 (flexible field gear rate) have not been set. 6) A value outside the limit of {1 to the number of control axes} or a non-continuous value (Parameter 1023 (servo axis number) contains a value out of the range from 1 to the number of axes, or an isolated value (for example, 4 not prceded by 3).- No. 1023 (servo axisnumber).

Position detection system fault in the n-th axis (axis 1-8) pulse coder
(disconnection alarm). Refer to diagnosis display No. 201 for details.

A speed higher than 524288000 units/s was attempted to be set in the n-th axis (axis 1-8). This error occurs as the result of improperly set CMR.

The contents of the error register for the n-th axis (axis 1-8) exceeded the limit. This error usually occurs as the result of an improperly set parameters.

The position deviation value when the n-th axis (axis 1-8) moves is larger than the set value. Refer to procedure of trouble shooting.

The position deviation value when the n-th axis (axis 1-8) stops is larger than the set value. Refer to procedure of trouble shooting.

Abnormal servo motor load has been detected. Alternatively, abnormal spindle motor load has been detected in Cs mode.

This alarm is generated when the spindle control unit is not ready for starting correctly when the power is turned on in the system with the serial spindle.
The four reasons can be considered as follows:
1) An improperly connected optic cable, or the spindle control unit

The difference in synchronous axis position deviation exceeded the set value.
