SV 026 ILLEGAL AXIS ARRANGE-
MENT
Parameter No. 1023 for specifying the arrangement of servo axes
is set incorrectly.
SV 027 ILL DGTL SERVO
PARAMETER
There is an illegal digital servo parameter.
– A correct motor model type is not set in parameter No. 1874.
– The number of pulses per motor rotation is not set in parame-
ter No. 1876.
– The direction of motor rotation set in parameter No. 1879 is
neither 111 nor –111.
SV 030 EMERGENCY STOP Emergency stop occurred
(when ENR, a bit of parameter No. 2001, is 1).
SV 031 EXCESS SPINDLE DIST
(SPDL)
Excess position deviation occurred for the spindle during rigid tap-
ping.
SV 032 LSI OVERFLOW (SPDL) Data for the LSI used for spindle control overflowed during rigid
tapping.
SV 050 ILLEGAL AXIS
SYNCHRONIZATION
Parameter No. 1023 is set incorrectly.
SV 055 Parameter No. 1023 is set incorrectly.
SV 056 Bit #6 of parameter No. 1817 is set incorrectly.
SV 99 SPINDLE–AXIS ERROR An amplifier alarm occurred during spindle contour control.
SV 100 SACOMP, VALUE
OVERFLOW
The value set for straightness compensation is not within the
range of –32767 to +32767.
M
SV 101 DATA ERROR (ABS PCDR) A correct machine position cannot be obtained because the abso-
lute pulse coder is faulty or the machine moved too far during pow-
er–on.
Axis type
SV 110 PULSE CORDER ALARM
(SERIAL A)
An error was detected in the serial pulse coder (serial A) or feed-
back cable.
Replace the cable or pulse coder.
(For details on the alarm, refer to the “FANUC AC Servo Amplifier
Maintenance Manual.”)
Axis type
SV 111 PULSE CORDER ALARM
(SERIAL C)
An error was detected in the serial pulse coder (serial C) or feed-
back cable.
Replace the cable or pulse coder.
(For details on the alarm, refer to the “FANUC AC Servo Amplifier
Maintenance Manual.”)
Axis type
SV 114 ABNORMAL REV. DATA
(SERIAL A)
The serial pulse coder (serial A) is abnormal. Replace it. Axis type
SV 115 ABNORMAL
COMMUNICATION (SPLC)
A serial pulse coder communication failure occurred.
Replace the pulse coder, feedback cable, or CNC axis board.
Axis type
SV 116 MCC WELDING ARARM The contact of the magnetic contractor (MCC) in the servo amplifi-
er has melted. For details, refer to the “FANUC AC Servo Amplifi-
er Maintenance Manual.”
Axis type
SV 117 ABNORMAL CURRENT
OFFSET
Digital servo current conversion is abnormal. Replace the CNC
axis board.
Axis type
SV 118 DETECT ABNORMAL
TORQUE
An abnormal servo motor load was detected. Reset to clear the
alarm.
Axis
SV 119 DETECT ABNORMAL
TORQUE (1ST SPDL)
An abnormal load was detected on the first spindle motor.
To reset the alarm, press the RESET button.
SV 125 EXCESS VELOCITY IN
TORQUE
In torque control, the specified maximum allowable velocity was
exceeded.
SV 126 EXCESS ERROR IN
TORQUE
In torque control, the maximum allowable accumulated movement,
specified with a parameter, was exceeded.
