allowable number of the skip signal inputs is specified by Q.
The total number of the skip signal inputs (i.e. the same value specified by Q) is stored
in
the variable specified by R.
Example
G81 T200 L2 ; (EGB mode on)
X_ ;
Z_ ;
G31.8 G91 C0 P500 Q200 R1 ; (EGB skip command)
After 200 times of skip signal inputs, 200 machine coordinate positions of the C axis
are stored respectively in the consecutive custom macro variables #500 - #699.
The total number of skip signal inputs (i.e. 200) is stored in the custom macro
variable #1.
3. Notes
(Note1) In the G31.8 block, only the EGB axis (work axis) should be commanded. When
another axis is commanded, the P/S alarm (No.5068) will occur.
(Note2) If P is not specified in the G31.8 block, the P/S alarm (No.5068) will occur.
(Note3) If R is not specified in the G31.8 block, the total number of skip signal inputs is not
stored in the custom macro variable.
(Note4) The numbers of custom macro variables specified by P and R must be the existing
ones. If any nonexistent variable is specified, the P/S alarm (No.115) will occur.
If all the variables ranged by P and Q are not among the existing ones, the P/S
alarm
(No.115) will occur, too.
(Note5) You can select the type of skip functions, normal skip function or high speed skip
function, by the parameter HSS(No.6200#4).
When high speed skip is selected, you can select a valid signal among high speed
skip signals by setting parameter 9S1 to 9S8 (No.6208#0 to #7).
(Note6) The parameters No.6201#0 and #1 are not effective for the G31.8 function.
The machine coordinate positions stored in macro variables do not include any
compensation amount based on position errors and servo time constant (loop gain).
