S-SPINDLE LSI ERROR

It is serial communication error while system is executing after power

supply on. Following reasons can be considered.

1) Optical cable connection is fault or cable is not connected or cable

is cut.

2) MAIN CPU board or option 2 board is fault.

3) Spindle amp. printed board is fault.

4) The spindle amplifier is under an abnormal condition. (The SPM in-

dication is A, A1, A2, or the like, depending on the type of the ab-

normality.)

If this alarm occurs when CNC power supply is turned on or when this

alarm can not be cleared even if CNC is reset, turn off the power supply

also turn off the power supply in spindle side.

If the spindle amplifier is under an abnormal condition, check the SPM

indication (A, A1, A2, or the like). Then, refer to the FANUC SERVO MO-

TOR ai series MAINTENANCE MANUAL (B-65285EN) or FANUC

SERVO MOTOR a series MAINTENANCE MANUAL (B-65165E) to

solve the problem.

750

SPINDLE SERIAL LINK START

This alarm is generated when the spindle control unit is not ready for

FAULT

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’s

power is OFF.

2) When the NC power was turned on under alarm conditions other

than SU-01 or AL-24 which are shown on the LED display of the

spindle control unit.

In this case, turn the spindle amplifier power off once and perform

startup again.

3) Other reasons (improper combination of hardware)

This alarm does not occur after the system including the spindle con-

trol unit is activated.

4) The second spindle (when SP2, bit 4 of parameter No. 3701, is 1)

is in one of the above conditions 1) to 3).

See diagnostic display No. 409 for details.

752

FIRST SPINDLE MODE CHANGE

This alarm is generated if the system does not properly terminate a

FAULT

mode change. The modes include the Cs contouring, spindle position-

ing, rigid tapping, and spindle control modes. The alarm is activated if

the spindle control unit does not respond correctly to the mode change

command issued by the NC.
