axis. For example, in three–dimensional tool compensation mode using an offset vector of which components are the X–, Y–, and Z–axes, when two–axis spline interpolation is performed with the two spline axes set to the X– and Y–axes, a movement along the Z–axis occurs, resulting in this alarm.

end point of smooth interpolation or spline interpolation, the end point and the point two points before are the same.

The parameter setting that determines the relationship between the rotation axis and rotation plane is incorrect.

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

mode change. The modes include the Cs contouring, spindle positioning, 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.

Replace the motherboard, then check whether the error recurs. If the error still occurs even after the replacement of the motherboard, report the conditions under which the error occurred (system configuration, operation, time and frequency of error occurrences, etc.) and the indicated internal error code to FANUC.

A communication error occurred in the I/O Link. CHx is channel number. aa and bb indicate internal error code.

If this error occurs, the possible causes are as follows: (1) Although the base expansion is assigned when the I/O Unit A is used, the

base is not connected. (2) A cable is not connected securely. (3) Cabling is faulty . (4) I/O equipment (I/O unit, Power Mate, etc.) is faulty .

ALARM LIST (SERIAL SPINDLE)

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). ³ See Appendix A.4, “Error Codes (Serial Spindle).”

Faulty location and remedy Description

NOTE*1

Note that the meanings of the SPM indications differ depending on which LED, the red or yellow LED, is on. When the yellow LED is on, an error code is indicated with a 2–digit number. The error code is not displayed on the CNC screen. When the red LED is on, the SPM indicates the number of an alarm generated in the serial spindle. ³ See Appendix A.3, “Alarms (Serial Spindle).”

Although neither *ESP (emergency stop signal; there are two types of signals including the PMC signal and PSM contact signal(*2)) nor MRDY (machine ready signal) is input, SFR (forward rotation signal)/SRF (reverse rotation signal)/ORCM (orientation command) is input.

When the spindle motor has a high–resolution magnetic pulse coder (Cs sensor) (bits 6 and 5 of parameter No. 4001 are set to 0 and 1, respectively), 128 /rev is to be set for the speed detector (bits 2, 1, and 0 of parameter No. 4011 are set to 0, 0, and 1, respectively). However, a value other than 128 /rev is set. In this case, the motor is not excited.

Although use of a high–resolution magnetic pulse coder (bit 5 of parameter No. 4001 = 1) or use of the Cs contour control function by the sensor (bit 4 of parameter No. 4018 = 1) is not set, a Cs control command is input. In this case, the motor is not excited.

Although use of the position coder signal (bit 2 of parameter No. 4001 = 1) is not set, a servo mode (rigid tapping, spindle positioning) or spindle synchronization command is input. In this case, the motor is not excited.

SFR/SRV is not input. Although Cs contour control mode is set, another op-

the presence of the differential speed mode function, Cs contour control is specified.

When bit 5 of parameter No. 4000 is set to 0 to indicate the absence of the differential speed mode function, the differential speed mode command (DEFMD) is input.

0 of parameter No. 401 1) is invalid. (The corresponding speed detector is not present.)

Although bits 2 of parameter No. 4001 is set to 0 not to use the position coder signal, a command for orientation by a position coder (ORCMA) is input.

Although orientation by a magnetic sensor is being performed, another operation mode is specified.

When the use of the slave operation mode function is set (bit 5 of parameter No. 4014 = 1), the use of a high– resolution magnetic pulse coder (bit 5 of parameter No. 4001 = 1) or the use of the Cs contour control function by the sensor (bit 4 of parameter No. 4018 = 1) is specified. These items cannot be set at the same time.

Although position control (such as servo mode or orientation) is being performed, a slave operation mode command (SLV) is input.

Although slave operation mode is set (SLVS = 1), a position control command (such as servo mode or orientation) is input.

Although bit 5 of parameter No. 4014 is set to 0 not to use the slave operation mode function, a slave operation mode command (SL V) is input.

Orientation is performed in incremental operation mode (INCMD = 1) first, then the absolute position command (INCMD = 0) is input.

Although the spindle amplifier SPM type 4 is not used, the use of the Cs contour control function by the sensor is set (bit 4 of parameter No. 4018 = 1).
