ILLEGAL CURRENT LOOP

The current control cycle settings (parameter No. 2004, bit 0 of pa-

rameter No. 2003, and bit 0 of parameter No. 2013) are incorrect.

Possible problems are as follows.

- For the two axes whose servo axis numbers (settings of parameter

No. 1023) are an odd number followed by an even number (a pair

of axes 1 and 2 or axes 5 and 6, for example), a different current con-

trol cycle is set for each of the axes.

- The requirements for slaves needed for the set current control cycle,

including the number, type, and connection method of them, are not

satisfied.

ILLEGAL HI HRV (250US)

Use of high-speed HRV is specified although the current control

cycle is 200 ms.

HI HRV SETTING ERROR

For the two axes whose servo axis numbers (settings of parameter

No. 1023) are an odd number followed by an even number (a pair of

axes 1 and 2 or axes 5 and 6, for example), the SVM for one of the

axes supports high-speed HRV control but the SVM for the other

does not. Refer to the SVM specification.

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

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).

When a serial spindle alarm occurs, the following number is displayed on

the CNC. n is a number corresponding to the spindle on which an alarm

occurs.

(n = 1: First spindle; n = 2: Second spindle; etc.)

NOTE*1

Note that the meanings of the SPM indications differ

depending on which LED, the red or yellow LED, is on.

When the red LED is on, the SPM indicates a 2-digit alarm

number. When the yellow LED is on, the SPM indicates an

error number that designates a sequence problem (for

example, when a rotation command is entered with the

emergency stop state not released).
