Part 1 Programming
α and β are movement commands which are specified by the absolute/increment values based
on the state of G90/G91
In the increment command, the increment value corresponding to the intermediate point should
be specified.
When the G29 block operation is performed, all specified axes can be reached to the appointed
point by the defined intermediate point by G28 code at the rapid traverse rate.
This positioning operation is from an intermediate point to the specified one which is similar as
the G00 positioning.
The application of G28 and G29 is shown below:
When G91 is performed:
G28 X1000.0 Y200.0; (From A to B till to R)
M00 ；
G29 X500.0 Y-400.0; (From R to B till to C)
This example is expressed that programmer do not need to calculate the actual movement
distance where from the intermediate point to the reference position. If the simultaneous 3 axes
control function is performed for the system, the G29 code is as follows.
G29 α ___ β ___ r ___
；
(Addresses α , β and r are selected from X, Y, Z and the additional axes A, B, C, U, V and W, if the
simultaneous control function of an additional axis does not select, the function of additional axis
simultaneous control can not be performed with any one of the others.)
The following commands can be performed when the simultaneous 4 axes function are
registered:
G29 α ___ β ___ r ___ δ ___ ；
Wherein, α , β , r, δ = X, Y, Z, A, B, C, U, V and W.
