181 FORMAT ERROR IN G81 BLOCK
(Hobbing machine, EGB) (M series)
G81 block format error (hobbing machine)
1) T (number of teeth) has not been instructed.
2) Data outside the command range was instructed by either T, L, Q or
P.
3) An overflow occurred in synchronization coefficient calculation.
Modify the program.
182 G81 NOT COMMANDED
(Hobbing machine) (M series)
G83 (C axis servo lag quantity offset) was instructed though synchro-
nization by G81 has not been instructed. Correct the program. (hobbing
machine)
183 DUPLICATE G83 (COMMANDS)
(Hobbing machine) (M series)
G83 was instructed before canceled by G82 after compensating for the
C axis servo lag quantity by G83. (hobbing machine)
184 ILLEGAL COMMAND IN G81
(Hobbing machine, EGB) (M series)
A command not to be instructed during synchronization by G81 was
instructed. (hobbing machine)
1) A C axis command by G00, G27, G28, G29, G30, etc. was
instructed.
2) Inch/Metric switching by G20, G21 was instructed.
185 RETURN TO REFERENCE POINT
(Hobbing machine) (M series)
G81 was instructed without performing reference position return after
power on or emergency stop. (hobbing machine) Perform reference
position return.
186 PARAMETER SETTING ERROR
(Hobbing machine, EGB) (M series)
Parameter error regarding G81 (hobbing machine)
1) The C axis has not been set to be a rotary axis.
2) A hob axis and position coder gear ratio setting error
Modify the parameter.
190 ILLEGAL AXIS SELECT In the constant surface speed control, the axis specification is wrong.
(See parameterNo. 3770.)The specified axis command (P)containsan
illegal value.
Correct the program.
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 program so that the serial spindle synchro-
nous control mode is released in advance.
197 C --AXIS COMMANDED IN SPINDLE
MODE
The program specified a movement along the Cs --axis when the signal
CON(DGN=G027#7) was off. Correct the program, or consult the PMC
ladder diagram to find the reason the signal is not turned on.
199 MACRO WORD UNDEFINED Undefined macro word was used. Modify the custom macro.
200 ILLEGAL S CODE COMMAND In the rigid tap, an S value is out of the range or is not specified.
Modify the program.
201 FEEDRATE NOT F OUND IN RIGID
TAP
In the rigid tap, no F value is specified.
Correct the program.
202 POSITION LSI OVERFLOW In the rigid tap, spindle distribution value is too large. (System error)
203 PROGRAM MISS AT RIGIDTAPPING In the rigid tap, position for a rigid M code (M29) or an S command is in-
correct. Modify the program.
204 ILLEGAL AXIS OPERATION In the rigid tap, an axis movement is specified between the rigid M code
(M29)block and G84 or G74 forM series (G84 or G88 forT series)block.
Modify the program.
205 RIGID MODE DI SIGNAL OFF Rigid mode DI signal is not ON when G84 or G74 for M series (G84 or
G88 for T series) is executed though the rigid M c ode (M29) is speci-
fied.Consult the PMC ladder diagram to find the reason the DI signal
(DGNG061.1) is not turned on.
206 CAN NOT CHANGE PLANE
(M series)
Plane changeover was instructed in the rigid mode.
Correct the program.
