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.

Position control system fault. Due to an NC or servo system fault in the reference position return, there is the possibility that reference position return could not be executed correctly. Try again from the manual reference position return.

Even though the n-th axis (axis 1-8) READY signal (MCON) went off, the servo amplifier READY signal (DRDY) is still on. Or, when the power was turned on, DRDY went on even though MCON was off. Check that the servo interface module and servo amp are connected.

The combination of the axis control card and servo software is illegal. The possible causes are as follows: a A correct axis control card is not provided. a Correct servo software is not installed on flash memory.

The axis control card is not provided.

The n-th axis (axis 1-8) servo amplifier READY signal (DRDY) went off. Refer to procedure for troubleshooting.
