NOTE
1 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.
2 If P is not specified in the G31.8 block, the P/S alarm
(No.5068) will occur.
3 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.
4 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.
5 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).
6 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).
