433
Number Message Description
194
SPINDLE COMMAND IN
SYNCHRO–MODE
A contour control mode, spindle positioning
(Cs–axis control) mode, or rigid tapping
mode was specified during the serial spindle
synchronous control mode. Correct the pro-
gram so that the serial spindle synchronous
control mode is released in advance.
197
C–AXIS COMMANDED IN
SPINDLE MODE
The program specified a movement along the
Cs contour control axis when the signal
CON(G027#7) was off. Correct the program,
or consult the PMC ladder diagram to find the
reason the signal is not turned on.
751 First spindle alarm detec-
tion (AL–XX)
In a system with serial spindles at-
tached, this is a warning alarm mes-
sage that indicates an alarm on the
spindle amplifier side to be displayed
on the CRT of the NC. An alarm on the
spindle amplifier side is displayed on
the spindle amplifier, as AL–XX (where
XX represents a number).
This alarm number (XX) is displayed by
latching the spindle alarm number de-
tected by the CNC as the cause of this
alarm.
752
FIRST SPINDLE MODE
CHANGE FAULT
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.
WARNING
In the spindle contour control mode, do not switch the
spindle gears. When the gears need to be changed put the
system in the spindle speed control mode first.
NOTE
In the T series machines, the spindle contour control
function and the spindle positioning function cannot be
used at the same time. If both functions are specified
simultaneously, the spindle positioning function takes
precedence.
