010 IMPROPER G–CODE Parameters for axis setting are not set cor-
rectly regarding G81. (No.7710,7771,4352,
or Cs axis setting).
Confirm the parameter setting.
181 FORMAT ERROR IN
G81 BLOCK
G81 block format error
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)Calculation of the synchronous ratio has
overflowed.
Modify the program.
184 ILLEGAL COMMAND
IN G81
A command not to be instructed during
synchronization was instructed.
1)The slave axis is specified by G00, G28,
G27, G29, G30.
2)Inch/metric conversion by G20, G21
was instructed.
3)Cs contour control mode is not selected.
186 PARAMETER SETTING
ERROR
Parameter error regarding G81
1)The slave axis has not been set to be a
rotate axis.
In the electronic gear box (EGB), when synchronization start or
cancellation is specified, synchronization is not started or canceled
immediately.
Instead, acceleration/deceleration is executed first. Therefore,
synchronization can be started or canceled while the spindle is rotating.
Also, synchronization ratio can be changed while the spindle is rotating.
At synchronization start, automatic phase synchronization is performed
such that the workpiece axis position matches the position corresponding
to the spindle one–rotation signal. With this synchronization, the same
operation is performed as synchronization start caused by a one–rotation
signal in hobbing synchronization when using the functions of a hobbing
machine.
The spindle corresponds to the EGB master axis and the workpiece axis
corresponds to an EGB slave axis (Servo axis or Cs contouring axis).
