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.

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

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).
